PREFACE
The National Surface Water Survey (NSWS) was begun in 1983 by the U.S. Environmental
Protection Agency (EPA) under the National Acid Precipitation Assessment Program (NAPAP), a
federal interagency task force mandated by Congress in 1980. The NSWS is a phased, systematic
study designed to: (1) characterize the present chemistry of surface waters in the United States
and classify them for more intensive study, (2) describe chemical temporal variability and
biological resources in subsets of surface waters, and (3) provide a foundation for documenting
trends in surface water chemistry through long-term monitoring. The NSWS is one of several
major projects in the Acid Deposition Aquatic Effects Research Program (AERP). This program,
one of many research programs investigating acidic deposition, is administered in the Acid
Deposition and Atmospheric Research Division: Office of Acid Deposition, Environmental
Monitoring and Quality Assurance, in the U.S. EPA Office of Research and Development.
The AERP addresses four primary assessment questions:
1. How extensive is the change in aquatic resources as a result of current levels of
acidic deposition?
2. What is the anticipated extent and rate of change to these resources in the future?
3. What levels of change in sensitive surface waters are associated with various rates of
acidic deposition?
4. What is the rate of change or recovery of affected systems, given decreases in acidic
deposition rates?
Five major research projects within the AERP specifically address these assessment
questions from a regional perspective. These projects and their goals are:
1. National Surface Water Survey (NSWS): To determine the present chemistry,
characterize the chemical temporal variability, and determine the key biological
resources of lakes and streams in potentially sensitive regions of the United States.
2. Direct/Delayed Response Project (DDRP): To predict changes in these aquatic
resources at various levels of acidic deposition, considering the terrestrial and aquatic
variables that influence these changes.
3. Watershed Manipulation Project (WMP): To verify that predictions of future change
are reasonably sound by manipulating watershed catchments or system components.
4. Episodic Response Project (ERP): To evaluate the regional importance of short-term
acidification resulting from episodic hydrologic events and its effect on the quality of
the biological environment.
5. Temporally Integrated Monitoring of Ecosystems Project (TIME): To test the validity
of predicted changes through long-term monitoring of regionally characteristic lakes
and streams.
The NSWS, including surveys of lakes and streams, addresses the first goal of the AERP.
Understanding the national-scale effects of acidic deposition on aquatic resources requires that
iii
-------
the present chemical status of surface waters be understood on large geographical scales. The
National Stream Survey - Phase I (NSS-I), conducted in the mid-Atlantic and southeastern
United States, was designed to describe, statistically, the present surface water chemistry on a
regional scale. Although cause-and-effect relationships between acidic deposition and surface
water response cannot be determined on the basis of NSS-I data alone, analysis of correlative
relationships within the NSS-I data base and other information do further our understanding
(and will continue to do so) of the extent to which mid-Atlantic and southeastern streams are at
risk due to acidic deposition. Determining the relationship between acidic deposition and surface
water chemistry is the goal of future activities within the AERP.
The National Stream Survey is funded and administered by the U.S. EPA, Office of Acid
Deposition, Environmental Monitoring, and Quality Assurance (OADEMQA) in Washington, D.C.
The Environmental Research Laboratory - Corvallis (ERL-C), with cooperating contracts with
Utah State University, Oregon State University, and Northrop Environmental Services, is
responsible for coordinating the activities of the Survey and for project design, data validation,
geographic analysis, and data interpretation. The Environmental Monitoring Systems Laboratory
- Las Vegas (EMSL-LV) is responsible for quality assurance and quality control, logistics, and
analytical support. Oak Ridge National Laboratory (ORNL) is responsible for developing and
maintaining the data base management system for the Survey. ORNL also participated in data
interpretation, provided statistical programming to implement the target population characteri-
zations, and did mapping and other geographic analysis.

ACKNOWLEDGEMENTS
The National Stream Survey - Phase I (NSS-I) in the Mid-Atlantic and Southeast built upon
the approach used for the NSS Pilot in the Southern Blue Ridge and also that employed in the
National Lake Survey. We owe a debt of gratitude all individuals involved in the design,
administration, implementation, and interpretation of these previous survey efforts. The National
Stream Survey represented an administrative and logistical challenge. Broad regional scale
probability sampling of a stream network required an innovative sampling design. The large
number of sample streams, the short time frame allowed for sampling, and the relative inacces-
sibility of many streams made the National Stream Survey a great challenge. The vigor and
dedication of hundreds of individuals, coordinated through the U.S. Environmental Protection
Agency, made the NSS-I possible. We here acknowledge only a few individuals who performed
key roles in the Survey, but we readily recognize that there are many others not mentioned
without whom the Survey would not have succeeded.
We gratefully acknowledge the citizens of the United States through the U.S. Environ-
mental Protection Agency Office of Environmental Processes and Effects Research (Director,
Courtney Riordan) for providing funding for the National Stream Survey.
We are grateful to Tom Murphy, ERL-C Laboratory Director, to Robert Lackey and Spencer
Peterson, Branch Chiefs at different times during the NSS-I project, and to Dixon Landers,

SECTION 1
INTRODUCTION
Field sampling for the National Stream Survey - Phase I (NSS-I) was conducted over a
two-year period in 1985 and 1986 by the U.S. Environmental Protection Agency (EPA) as part of
the National Acid Precipitation Assessment Program (NAPAP). In 1985, a Pilot Study was
conducted in the Southern Blue Ridge mountains to demonstrate the feasibility of a synoptic
stream survey (Messer et al., 1986, 1988). In 1986, Phase I sampling was conducted in sub-
regions of the mid-Atlantic and southeastern United States. The results of these surveys are
presented in the first volume of this report.
This second volume of the NSS-I report presents basic data and provides supplemental anal-
yses of populations that are not included in Volume I. Section 2 of Volume II lists selected
physical and chemical variables measured at each stream sampling location and visit. Section 3
presents a series of maps, one for each subregion of the survey, showing the lower node
sampling location for each reach labeled by its NSS-I reach identification number (RCH_ID).
The stream name, state, county, latitude, and longitude of each lower node sampling location are
listed in Section 4 in two different formats: first sorted by RCH_ID and then by slate and
county names. The regular stream reaches identified in the survey's Stage II sampling design
(see Section 2.4 of Volume I for more details on site selection procedures) are listed separately
from the special interest sites that were sampled during the survey. In Section 5, descriptive
statistics and population distribution functions are presented for selected physical and chemical
variables stratified by region and by subregion. The statistics presented in Section 5 are for
the index values derived separately at the upstream and the downstream nodes of the target
reaches. Selected physical data describing individual reaches and their watershed characteristics,
including watershed area, stream order, elevation, gradient, stream width and depth, and the
overall sample weights used in calculating population estimates, are listed in Section 6. Selected
chemical data from each reach are listed in a series of four tables in Section 7. Separate tables
are presented for the following groups of variables: major cations and anions (Table 7-1); acid
neutralizing capacity, pH, and related variables (Table 7-2); aluminum, other metals, and dis-
solved organic carbon (Table 7-3); and nutrients and other water quality variables (Table 7-4).
Not all the variables contained in the NSS-I data base are presented in this volume. For addi-
tional details on the contents of the NSS-I data base, see Sale (1988).

SECTION 2
DEFINITION OF VARIABLES
Physical and chemical variables were measured at each stream sampled in the survey (Table
2-1) using standardized protocols (see Volume I, Section 3). These variables were selected to
satisfy the primary objectives of the survey: to construct a geographically extensive set of
information from which the extent and chemical status of streams potentially affected by acidic
deposition could be determined. The data were incorporated into a computerized data base using
SAS software (Volume I, Section 3.8; Sale, 1988) and were subjected to exhaustive verification
and validation analyses (Volume I, Section 3). Table 2-2 presents definitions of variables
presented in this volume, including the units of measurement and a brief description of the
methods of analysis. More extensive descriptions of water sampling and chemical analytical
methods can be found in Hillman et al. (1987), Drouse et al. (1986), and Hagley et al. (1988).
Not all the variables contained in the NSS-I data base are presented in this volume because
of space limitations. For example, secondary variables that were calculated from the original
variables, such as sum of cations or sum of anions, are not presented. Certain other qualitative
watershed characteristics observed during site visitation, such as local land use or stream
habitat, are also not presented here. The intent of this data presentation is to provide enough
information to permit replication of any of the analyses in the report. Only those variables
reported in this volume are listed in Table 2-2.

SECTION 3
SUBREGION MAPS
This section provides maps showing the location of the general NSS-I study area and all
the streams that were sampled. Figure 3-1 shows the major NSS-I subregions within which
survey activities were confined. As described in Section 2.3 of Volume I, these areas were
previously identified as being susceptible to acidic deposition. Figures 3-2 through 3-10 show
the individual sampling locations within each subregion. Regular, special interest, and non-
interest streams are shown in these figures with a substring of the stream identification number
used as a label on each point for cross reference purposes. The partial identification number
shown on the maps consists of the fourth through eighth digits of the full identification number
for all Phase I sites except for the Pilot Survey (Figure 3-6). For the Southern Blue Ridge
subregion, the fourth through seventh digits are shown because the Pilot Survey used identifica-
tion numbers that were one digit shorter. Only the lower node of each stream reach is shown
in these figures. The two strata of regular streams are related to the NSS-I sampling design as
explained in Volume I, Section 2.4. The noninterest streams shown are those that were identi-
fied as influenced by acid mine drainage or other factors, including episodes of rainfall, tidal
effects, etc. The reasons for noninterest classification are listed in Section 4 (Table 4-3). The
regions and subregions studied in Phase I of the survey are the following:

SECTION 4
STREAM NAMES AND LOCATIONS
This section lists the names and location data for all streams that were sampled in the
NSS-I. Regular streams (those that were part of the stratified random probability sample
described in Section 2, Volume I) are listed in Tables 4-1 and 4-2. For ease of use, two
formats have been used in these listings: Table 4-1 presents regular streams ordered by their
identification number, and Table 4-2 presents the same data organized by state and county
names. The tables include the stream identification number (RCH__ID), the state and county
name within which the lower node of each reach is located (STATE 1 and COUNTY 1), the stream
name taken from USGS maps (STRMNAM), the latitude and longitude (in decimal degrees) of the
lower node of each reach (LAT_STD and LON_STD), the name of the 1:250,000-scale USGS map
from which the stream was originally identified (QUAD), and the NSS-I subregion to which each
stream is assigned (SUB_ID; see Figure 3-1). In both Tables 4-1 and 4-2, sites that were
determined to be noninterest are identified with an asterisk beside their RCH_ID. The reasons
for designating sites as noninterest are listed in Table 4-3. The special interest sites visited
during Phase I are listed in Table 4-4 sorted by their identification numbers and in Table 4-5
sorted by state and county.

SECTION 5
POPULATION ESTIMATES OF SELECTED PHYSICAL AND CHEMICAL VARIABLES
The major product of the NSS-I is the set of cumulative distribution functions that
describe physical and chemical attributes of various populations of stream reaches. These
population distribution functions can be produced for different types of stream resources, such
as the number, length, and combined watershed area of stream reaches. They are designed to
satisfy the major objective of the survey: to describe the percentage, extent (e.g., number,
length, and drainage area), and geographic location of streams that either are presently acidic or
that could become acidic in the near future. The population distributions presented in this
section are derived from upstream and downstream chemical index values of samples in the
refined target population. When more than one sample was taken at a site, index values are the
mean of multiple samples (Section 2.5, Volume I). The population of interest consists of those
streams that were not affected by complicating factors that could mask the potential influence
of acidic deposition, such as acid mine drainage, tidal influences, or insufficient stream flow.
Full details of the statistical design of the survey can be found in Volume I, Section 2.4, and in
Overton (1987). A brief discussion of the survey design and its implications for statistical
analyses is presented here. Not all the variables sampled or calculated during the survey are
presented. The selected attributes that are described in the distribution functions presented are
listed in Table 5-1.
5.1 APPLICATION OF THE SURVEY DESIGN
The use of NSS-I data to make population estimates must be consistent with the survey
sampling design (see also Volume I, Section 2; Overton, 1986, 1987; Sale, 1988). The basic
NSS-I sampling unit is the stream reach, delimited by upper and lower nodes (the upstream end
or a confluence of blue-line streams on l:250,000-scale USGS maps). At each reach, water
chemistry samples were taken at both lower and upper nodes, and one or more visits were made
to each node. In the Mid-Atlantic Region (subregions ID, 2Cn, 2Bn, and 3B) each node of each
reach was visited on two occasions. Only one visit was made to reaches in the Southeast
Region (subregions 2D, 2X, 3A, and 3C). In the Southern Blue Ridge subregion (2As), all nodes
were sampled once in the summer, but during the spring, lower nodes were sampled as many as
four times and upper nodes were sampled from zero to two times (Messer et al., 1986, 1988). In
the final NSS-I data set, each sample is identified by a unique combination of three variables:
(1) the reach identification number, RCH_ID, (2) the visit or sample replicate number, SAMRN,
and (3) the sampling node, NODE (upper=U or lower=L). The stream identification number,
STRM_ID, consists of RCH_ID and NODE concatenated together.
5.1.1 Sample Weights
The NSS-I sampling locations were identified from the population of stream reaches by
means of a systematic random sampling procedure. Because sample reaches were not selected
with equal probability, each reach has a sample weight that indicates how many other reaches in
the population it represents. This weight is inversely proportional to the reach's probability of
being selected in the sample. It represents the product of sample weights for two stages of
sampling. In the first stage, reaches were selected in association with an 8-mile square grid of
dots overlaying a l;250,000-scale USGS map. The probability of including a reach this sample is
directly proportional to its direct watershed area, aA. Thus the first stage weight is equal to

the area per grid point (64 mi2) divided by a^ If ax is less than 0.2 mi2, the area per grid
point is divided by 0.2. Direct watershed area is thus "scored" to 0.2 to reduce the variance of
the estimator (Overton, 1987). The second stage of selection has a more complicated weight
calculation (Volume I, Section 2.4.5), and the result is found in the variable WC in the data
base. The final sample weight for each reach, W, is calculated as follows:
W = WC x 64/a-t
(if 3j < 0.2 mi2, 3j is scored to 0.2 mi2)
Reaches that were located in areas classified as low ANC areas based on geology (Omernik
and Kinney, 1985; Omernik and Powers, 1983) are separated into a second stratum (STRATUM=2)
and explicitly overrepresented in the NSS-I sample. The final sample weight for this second
stratum reflects the true frequency of these low ANC reaches in the target population (see
Volume I, subsection 2.4.5).
Whenever statistical descriptions of NSS-I stream populations are made, the sample weights
must be used. In general, weights should be used in calculating frequency distributions and
other univariate analyses of chemistry data, including calculations of means. However, NSS-I
data users are discouraged from using the weights in bivariate or multivariate explorations of
the data.
5.1.2 Sample Stratification.
NSS-I reaches from different strata are assumed to be independent, while reaches within a
stratum are not. In the survey design, each subregion is a different stratum, with the Mid-
Atlantic subregions further stratified prior to site selection into a routine stratum and a low
ANC stratum (expected to have ANC < 50 ^teq L"1 based on Omernik and Powers, 1983). In the
data base, two variables are required to identify samples from the same strata: the subregion of
the reach, SUB__ID, and the stratum variable, STRATUM. It is possible to construct a variance
estimate for the sample from the joint inclusion probabilities, Wy (see pages 8-10 in Overton,
1987; subsection 5.1.5). If reaches i and j are from different strata, then their joint inclusion
probability is calculated as Wy = WjW.-. If they are in the same stratum, then
Wy = [(W, + Wj)/2 - WjWjlAn-1)
where n is the effective sample size (ESS). The concept and application of Stage I and Stage II
ESS are detailed in Sale (1988) and Overton (1987).
5.1.3 Subpopulations
The population of stream reaches targeted by the NSS-I is described in Volume I, Section
2.4, and elsewhere (Messer et al., 1986, 1988). Basically, the NSS-I samples represent the
population of blue-line streams shown on USGS l:250,000-scale maps that have watershed areas
less than 155 km2 (60 mi2). The subset of samples in the NSS-I population of interest is not
excessively influenced by point-sources of disturbance such as acid-mine drainage, nor were
observations during precipitation episodes included. In the data base, the drop code variable,
DRPCDE, is set to values >2 for noninterest samples (e.g., for samples influenced by acid mine
drainage). It is important to recognize that one observation at a particular reach may be
designated noninterest (e.g., because of stream episode influence), whereas a different sample, or
61
-------
SAMRN value, may be used for calculating index values for the population of interest. When
only one node of a particular reach is excluded from the population of interest, the alternate
node remains in the target population but with a DRPCDE = I. The results presented in Section
5.2 include all samples with DRPCDE < 1. A sample subset with DRPCDE < 1 designates a sub-
population in which both nodes are in the target population. Data from special interest sites
are also excluded from analyses of the target populations.
Using the NSS-I statistical procedures, it is possible to describe any meaningful subpopu-
lation of target stream reaches that can be distinguished within the sample (Overton, 1987). A
few examples are upper and lower node subpopulations, headwater and higher order stream sub-
populations, and populations within geographic areas based on political or ecological boundaries.
5.1.4 Calculation of Distribution Functions
The cumulative distribution functions (CDF) and other distribution functions weighted by
stream length and by watershed area are generated as the primary survey output. The CDF
format is preferable over histograms for several reasons. First, observations of water chemistry
do not tend to follow normal or even symmetrical distributions, so that the mean concentrations
cannot be easily compared. Second, quantiles (e.g., median) allow statements to be made about
the proportion of resources with concentrations above or below some threshold value. These
quantiles cannot be observed on a histogram. Finally, construction of a histogram requires the
selection of partition widths, often a difficult and arbitrary task when dealing with strongly
tailed distributions. In the CDF, there is no need for artificial partitions of the sample data
values. The data are presented without any modifications or reduction in detail.
After sample weights have been calculated and the drop list applied (excluding observations
with a DRPCDE < 1), the first step in calculating a CDF is to subset the data into a subpopula-
tion of interest. The second step is to ensure that there is one and only one observation (index
value) per reach, since the weights indicate the number of reaches represented. A single index
value for each reach can be derived by averaging observations from multiple visits or by
analyzing reach visits (SAMRN = 1 and 2) as separate populations of interest (e.g., in the Mid-
Atlantic region). Similarly, data from the upper and lower nodes can be averaged or analyzed
separately (NODE = L and U). Population distributions can be calculated for separate visits or
nodes using the same population expansion procedure (Overton, 1986, 1987; Sale, 1988).
The distribution functions can be calculated for any resource size attribute of interest to
the investigator. In this volume, numbers of reaches, areas of total watershed, and lengths of
reach are all presented. For example, if length of stream is the resource size attribute of
interest, a determination can be made of the combined length of stream (t) in Pennsylvania
having pH less than 5.0 at reach lower nodes. This is calculated as the sum of the product of
sample weight and reach length over all reaches that are in Pennsylvania and that have a
measured pH < 5.0 at their lower nodes. This produces one point on the length distribution
function at pH - 5.0. The complete distribution function (fc(x)) is constructed by sorting
samples in ascending order of pH. For each pH value occurring in the sample, the cumulative
sum of the sample weighHength products over samples with pH < x constitutes l(x), interpreted
as the combined reach length in the population with pH less than or equal to the current value
of x. Note that for multiple samples having the same pH value, the last l(x) of the group is
the correct estimate for that pH.

-------
5.1.5 Calculation of Variance and Confidence Bounds
The calculation of a variance estimate for any population estimate T(x) is described in
Volume I, Section 2.4. The formula for the variance estimate is
where y is the reach attribute of interest, Wy is the joint inclusion probability (section 5.1.2),
and W is the reach weighting factor. The variance in the population estimates for the different
reach attributes (reach numbers, length, watershed area, etc.) is calculated by assigning different
definitions to y (y=l for number estimates, y=ai+a2 for total watershed area estimates, and
y=length for length estimates).
The first term in the variance calculation can be calculated at the same time that T(x) is
calculated for each unique value in the sample. The second term requires pairwise comparisons
of each sample with all of the other samples in the subpopulation that are in the same stratum.
Samples in different strata are independent of the current sample reach (i.e., Wy=WjWj), and in
these cases the second term of the variance equation equals zero. The standard error of the
estimate is calculated as the square root of the variance. Upper one-sided 95% confidence
bounds were then calculated by multiplying the standard error by 1 .645 and adding that value to
the population estimate (*t(x)).
5.2 POPULATION DISTRIBUTION FUNCTIONS
The figures in this section present descriptive statistics and population distribution func-
tions for selected physical and chemical characteristics (Table 5-1) of two populations of
interest: the population of NSS-I target reaches described by their upper node attributes and
the population of NSS-I target reaches described by their lower node attributes. Figures are
shown for all subregions included in the Phase I survey. In addition, resource estimates are
presented for the Interior Mid- Atlantic Region (subregions ID, 2Bn, and 2Cn) and the Interior
Southeast Region (2X, 2D, 3A, and 2As). The index values used in these population descriptions
are averages of multiple samples from a node where multiple visits were made. Three types of
distribution functions are presented. Two CDFs are presented to describe the number of reaches
with specified characteristics for both upper and lower nodes. Stream length and total water-
shed area distributions are presented for the lower nodes only. The length distribution func-
tions in this volume should not be confused with those presented in Volume I, which used an
interpolation algorithm to combine upper and lower node index values. The length distribution
functions presented here assign the lower node chemistry to the entire length of the stream
reach. All distributions and statistics are appropriately weighted to represent the population of
interest (i.e., acid mine drainage streams and streams affected by other complicating factors
have been excluded).
To read these figures, start by choosing a specific value of a reach attribute, x (e.g.,
pH=6.0), and read the function values of the two curves: F(x), the solid line, and Fu(x), the
dotted line. In an ascending curve, the value of F(x) is the estimated proportion of reaches in
the target subpopulation having values of the attribute less than or equal to x. It is estimated
with 95% confidence that the true proportion does not exceed the value of Fu(x). Some distri-
butions are plotted as a decreasing function of x if higher values are of greater interest. For
63
-------
these descending curves, the function values are read as the estimated proportion of reaches
having values of the attribute greater than or equal to x. If desired, a one-sided lower
confidence bound can be generated for the population distributions by projecting an identical
distance below F(x). This lower confidence interval is not presented in the figures because of
possible confusion with two-sided confidence bounds which would have different widths.
A tabular presentation of population estimates is given at the bottom of each page. Total
resource estimates and their standard errors are shown in the first row of each table. These
resource estimates should be interpreted as the number of reaches, length of reaches, or total
nested watershed area in the total population of interest for the specified region or subregion.
In the second section of the table, percentiles of the population distribution functions are listed.
From this part of the table, it is possible to extract specified percentages of the population of
interest having physicochemical attributes less than or equal to the tabulated percentile values.
Below the section of the table labeled Population Estimates, sample and population summary
statistics are presented, including the number of reaches sampled from the population of interest
and the minimum and maximum values in the sample. The population mean and standard devia-
tion shown at the right are extrapolated from the sample data using appropriate sample weights.
5.3 INTERPRETATION OF NSS-I DISTRIBUTION FUNCTIONS
Frequency distribution curves, the top two graphs in each of the distribution function
figures (Figures 5-1 to 5-329), indicate the proportion of the total number of reaches that were
above or below some reference value. Frequency distributions are provided based on index
chemistry at the upstream (top left) and downstream (top right) reach nodes. These distribu-
tions are fairly easy to understand, but they treat reaches of different length and discharge
equally. Thus they may present, for example, a misleading picture of low ANC waters if ANC is
correlated with reach length, drainage area, discharge, or position in the drainage network.
Expressing the estimates as length distributions—lower left graph in the distribution
function figures (Figures 5-1 to 5-329)~gives a better picture of the total resource, but still
treats large and small streams of the same length equally. Furthermore, this type of length
distribution estimate assumes that the value of the chemical variable is uniform throughout the
length of the reach, and equal to the value of the lower node (in these figures). An alternative
is to interpolate the reach chemistry between upper and lower reach ends. Results from this
type of analysis for ANC and pH are presented in Volume I, subsection 6.2.5. This approach,
however, assumes a linear change in chemistry between the upper and lower reach ends.
The lower right graph in the distribution function figures (Figures 5-1 to 5-329) displays
the population estimates based on total watershed area (A_WS) of the target reach lower nodes.
When multiplied by an appropriate net precipitation index value, watershed area can be used to
estimate discharge. Total watershed area (discharge index) distribution curves indicate, on the
basis of watershed area, the proportion of target reaches above or below a given reference value
of a chemical variable. The total population of refined target reach lower nodes within the
NSS-I area include drainages ranging from 0.5 to 149 km2, with smaller drainages nested within
larger ones. The estimated total watershed area of 1,188,064 km2 for the NSS-I target area
therefore includes drainage areas counted more than once and should not be construed to repre-
sent the total land area drained by the network of target reaches. The best interpretation of
the curves as they are presently shown is that they estimate the instantaneous, discharge-
weighted distribution of the chemical variables over the downstream nodes of all target reaches
in the population, assuming that discharge is proportional to drainage area only.
