INTRODUCTION
The Florida Department of Environmental Protection (FL-DEP) is
directing efforts to evaluate the overall health of the lower St.
Johns River system in the vicinity of Jacksonville, Florida. As
part of this initiative, the effects of several municipal
wastewater discharges to the estuarine system are being
investigated.
In the course of this analysis the FL-DEP has requested the
assistance of the Environmental Services Division (ESD) to help
identify the circulation patterns of the wastewaters being
discharged to the river through submerged outfalls. In proceeding
with this request, ESD in conjunction with the FL-DEP has conducted
three studies on the lower St Johns. In June, 1991 a circulation
and water quality study was conducted of the Mandarin POTW
discharge and a description of the circulation patterns at the
proposed Royal Lakes discharge site. Then in September of 1992 a
similar assessment was made of the Arlington East POTW discharge to
the St. Johns River. This third study, conducted during May, 1996
focused on the Jacksonville Southwest POTW discharge which is
located near the Jacksonville Naval Air Station (NAS).
Results of this study as well as the previous circulation and
water quality studies serve to define the areas of the estuary that
are subjected to the wastewater plumes.
The study, which was conducted during the period of May 6 -
11, 1996 focused on defining the dilution and dispersion
characteristics of the Jacksonville Southwest POTW in the St. Johns
1

-------
River estuarine system. Interrelated to these hydrographic
considerations, water quality measurements were made in the area
potentially effected by the discharge plume.
CONCLUSIONS
•	Dye tracing of the Jacksonville POTW effluent plume
indicates that dilutions of 190:1 to 68:1 (0.5% to 1.5%
effluent) occur within a 500 meter wide by 4000 meter long
path near the western shore of the River.
•	Semidiurnal tides with a mean range of 1.07 feet were
recorded during the study.
•	Winds were predominantly from the southeast and averaged 2.7
meters/second with sustained winds of 3.3-4.5 meters/second.
The effect of these winds was to accentuate the dye cloud
movement to the western shore of the river.
•	Fixed current meters recorded mean ebb tide velocities of
0.22 to 0.30 meters/second and flood tide velocity means of
0.18 to 0.28 meters/second. These differences (approximately
10%) reflect the dominance of the fresh water flow in this
estuary.
•	Mathematical model simulations with the CORMIX model agree
favorably with the field tracer data. The model predicts
dilutions of 100:1 in the near field and 1000:1 within 6000
meters from the outfall.
•	Nutrient levels were similar to those experienced in
previous studies of the St Johns River.
2

-------
•	Algal Growth Potential Tests (AGPT) show that these waters
are enriched but below threshold values indicative of highly
productive waters. Nitrogen was the limiting nutrient at all
stations.
•	Dissolved oxygen levels remained above 6.0 mg/1 during the
study. Diurnal variations in dissolved oxygen levels appear
to be more dependent on tidal exchange than on localized
water column production and respiration.
•	Salinity ranges reflected the location of the stations
within the estuary. All values were less than 5 PPT.
•	Reaeration rate coefficient of 0.74 1/day was estimated by
means of the floating dome method.
STUDY AREA
The general study area is located in the vicinity of
Jacksonville, Florida (Figure 1). The St Johns River in the area of
the discharge features a depth of 1 to 5 meters and receives a mean
semi-diurnal tide with a range of 0.27 meters (0.9 feet) - NOAA
tide tables. The Jacksonville Southwest POTW discharges
approximately 6 MGD to the river through a submerged outfall
located adjacent to the Jacksonville Naval Air Station (Figure 2).
The outfall's diffuser section, consisting of 5 risers and ports,
begins approximately 625 feet from the shoreline and terminates
approximately 1120 feet from the shore (Figure 2 detail).

STUDY OBJECTIVES
The overall objective was to define the circulation patterns
of this discharge in the St Johns River. In order to address this
objective, an intensive survey was conducted during the period of
May 6-11.
The following were the specific objectives of this study,-
•	Determine the dilution of the effluent in the receiving
waters during a tidal cycle.
•	Estimate the accumulative concentration of the
wastewater under long term conditions.
•	Determine the water quality characteristics in the
vicinity of the discharge plume.
•	Provide an estimate of Reaeration as well as community
dissolved oxygen production and respiration in the
receiving waters.
METHODS AND RESULTS
The following provides a description of the study methods
and results. Methods followed field and laboratory Divisional
Standard Operating Procedures (SOP's). Figure 3 depicts the
sampling stations while, Tables 1 & 2 provide respectively, a
description of the sampling and laboratory requirements.
Dye Dilution Study
Circulation and dispersion of the Jacksonville SW POTW
effluent in the ambient waters was measured by means of a dye
4

-------
dilution study. The basic strategy involved releasing a dye tracer
(Rhodamine WT) into the POTW discharge line to the St Johns River
in a continuous fashion for a semidiurnal (12.5 - 13 hour) tidal
cycle. Boat mounted flow-through fluorometers were then used to
measure the circulation and mixing of these traced waters in the
estuary. Measurements of tracer concentrations were made at
selected locations during the initial injection period as well as
at 6 to 12 hour slack tide sampling intervals for 2 days following
the injection period. The "Superposition Principal" developed by
the U.S. Geological Survey (1) was applied to the tracer data to
develop an estimate of the wastewater dilutions in the river. In
this method, consecutive time-concentration curves from a
conservative tracer released (in proportion to effluent flow) over
a single tidal cycle are superimposed to develop estimations of
ultimate (steady-state) concentrations in the estuary. Resultant
accumulative tracer concentrations can then be correlated to the
conservative components of the wastewater.
The tracer was injected into the effluent during the period of
0400 to 1700 on 5/8/96. This period commenced on a high tide,
followed through an ebbing tide and then return to a high tide
(Figure 4) .
During this period the tracer was injected into the discharge
line in a continuous fashion by means of a precision metering pump.
The point of tracer injection into the 48" discharge line was at a
manhole 16,000 feet from the POTW and located adjacent to the river
on the NAS property (Figure 2). From this point the line extends
5

-------
625 feet into the St Johns River where the discharge is introduced
into the River by way of a submerged outfall diffuser. The
diffuser, features 5 risers located along its 495 foot length. Thus
the terminus of the most seaward riser is located 1120 feet from
the shore.
An effluent to tracer dilution of 1000 PPB was targeted. In
order to develop the desired tracer dilution in the effluent the
effluent flow rate was monitored at the POTW at 30 minute
intervals. These rates, adjusted for residence time in the 16,000
foot sewer line were then used to pace the tracer injection rate
into the manhole. During the 13 hour tracer injection period the
effluent flow averaged 5.08 MGD (average of 5.13 MGD during the 5
day study period, Figure 5). A total of 19 Liters of Rhodamine WT
dye was injected in a flow proportional manner into the discharge
line. These rates produce a calculated tracer concentration in the
effluent of 950 PPB.
Monitoring of these traced wastewaters in the estuary
commenced upon release of the tracer and were accomplished by two
crews utilizing boat-mounted flow-through fluorometers. Monitoring
was concentrated on transects established along Latitude/Longitude
lines, as well as keyed to channel markers. Positioning was
provided by boat-mounted Global Positioning System (GPS) and Loran
equipment. In the vicinity of the Jacksonville SW outfall, buoys
were deployed to provide a higher degree of positioning control
near the zone of initial dilution (ZID). These buoys were set at
the seaward end of the diffuser as well as at 100 meters east, west
6

-------
and north of the diffuser end.
As shown on Figure 4 the traced effluent was monitored for 52
hours with monitoring cycles occurring at 4 low tide phases and 2
high tide phases. The first low tide monitoring (0900 - 1200 on
5/8/96) commenced during the initial injection period. Ebb tide
currents distributed the effluent along the western shore of the
river (Figure 6). On the following flood tide (1515 - 1900 hours on
5/8/96), still within the injection period, the dye cloud movement
reversed and moved southerly along the NAS property and continued
to remain against the western shore (Figure 7) . Samples collected
at the mouth of the Ortega River by means of an automatic sampler
confirmed that the traced effluent entered into the Ortega River
system during the first flood tide.
In a similar manner the dye cloud remained along the western
shore during the subsequent monitoring conducted at consecutive
high and low slack tides for a period of 52 hours (Figures 6-11).
Due to the dominance of the freshwater inflow into the estuary the
dye cloud moved seaward on each consecutive tide. By the end of the
fifth low tide following the tracer injection most of the dye cloud
had cleared the northern extremes of the study area at US highway
90 (Figure 11).
The steady-state (ultimate) tracer concentrations were
estimated by summing the fate of the 13 hour injection over several
(in this case 5) low tide cycles. Figure 12 depicts the estimated
"steady-state" low tide dye tracer levels for the conditions
encountered during this survey. As shown the traced effluent cloud
7

-------
concentrated along an area 4000 meters long by 500 meters wide near
the western shore of the river. Tracer concentrations in this area
were in the range of 5 to 14 PPB which represents effluent
dilutions of 190:1 to 68:1 (0.5% to 1.5% effluent) . Examples of the
time-concentration curves used to develop these steady-state
estimates are depicted in Appendix A.
Hydrographic Data
In conjunction with the tracer study, a water level recorder,
a recording wind meter and 6 buoy mounted recording current meters
were positioned (Figure 3) to measure the dynamics associated with
the dye cloud movement.
Semidiurnal tides with a mean range of 1.07 feet was recorded
during the study period (Figure 4). This is slightly greater than
the mean tide range of 0.9 feet described for this area in the NOS
Tide Tables.
The recording wind meter collected wind speed and direction at
5 minute intervals from 1730 on 5/7/96 to 0930 on 5/10/96 (Figure
13 and Appendix B). Winds were predominantly from the southeast and
averaged 2.7 meters/second. Sustained winds of 3.3-5.4
meters/second were frequently recorded. The affect of these
southeasterly winds was to accentuate the dye cloud movement to the
western shore of the river (Figures 6-12} .
Buoy mounted current meters were installed at stations SW-l
through SW-5 (Table 1 and Figure 3). These meters were tethered at
mid-depth and programmed to collect and store current speed and
8

-------
current direction data as well as conductivity, salinity and
temperature data at 2 to 5 minute intervals for the study period.
The meter positioned at station SW-1 (the southern most station -
see Figure 3) became fouled.
Figures 14 - 18, Tables 3-6 and Appendix C contain the
results of these current meter deployments. As shown on Figure 18
currents patterns reflected the freshwater dominance of the
estuary. Consistent among the stations was higher ebb tide
velocities when compared to flood tide components. As shown ebb
tide velocities averaged 10% greater (0.25 vs 0.23 meters/second)
than the flood tides. Also apparent was the similarity of the
pattern of the velocity vectors (Figure 18) and those of the dye
cloud configuration (Figures 6-12) .
Hydrographic Model Analysis
In an attempt to predict dilution levels of the Jacksonville
SW POTW under the existing conditions a plume model was applied.
The model used was Cormix, developed by G.H. Jirka and P.J. Akar of
Cornell University (2) . Input data included effluent discharge
characteristics (flow and density), outfall design and, the
receiving water density and current characteristics. The data base
used for comparison purposes was the first ebb tide occurring
during the tracer injection period i.e. the morning of 5/8/96.
Results of the computer model simulations with a listing of
the input parameter values are given in Appendix D. Comparisons of
model simulations to the field dye cloud data are depicted in
9

-------
Figure 19. Model runs were made using two flow regimes and two
diffuser designs. Runs I and IA were made with "steady flows" based
upon the average velocity recorded in the ebb tide cycle. Runs II
and IIA were made with a tidal varying flow based upon the peak
tide velocity recorded in the ebb tide cycle. Runs I and II are for
the existing multiport diffuser design and Runs IA and IIA are
simulations for a single port discharge. In general the model
simulations compare favorably with the tracer data (Figure 19).
Tracer concentrations of 10 PPB or less (dilutions of 100:1) occur
near the end of the diffuser and dilutions of 1000:1 (tracer levels
of 1 PPB) occur within 5,000 - 6,000 meters from the outfall.
As shown, the model outputs (Runs IA & IIA) for the simulated
single port discharge compare more favorably to the field
observations in the near field than does the outputs for the
existing multiport configuration. This disparity may be due in part
to the effect in this shallow water environment of the south-
southeasterly winds. Since the direction of these winds align
closely with the orientation of the diffuser section the dispersion
of dye cloud may have been restricted.
Water Quality Measurements
Water quality measurements focused on determinations of
nutrient levels, algal growth potentials and dissolved oxygen
dynamics.
10

-------
Chemical Analysis
Water quality samples for nutrient, total organic carbon and
total suspended solids analysis were collected at the 5 stations
during both an ebb and flood tide sampling event (Figure 3). Two
composite samples of the Jacksonville SW POTW effluent were also
collected during the study period and subjected to the same
analysis as the river samples. Analytical results (Table 7)
revealed no remarkable differences between the water quality in the
5 river stations. Nitrogen, phosphorus, total suspended solids and
total organic carbon levels detected during both the high and low
tide sampling events were very similar to those experienced in this
reach of the river during the study of the Mandarin POTW conducted
during June, 1991.
Algal Growth Potential
Algal Growth Potential Tests (AGPT) were conducted on samples
collected from three stations (SW-1, SW-3 and, SW-5) during both
tide phases (Figure 3). The algal test organism Selenastrum
Capricornutum were subjected to waters collected from these
stations to measure maximum growth potential of marine algae based
upon available nutrients in the sample. Secondly, nutrients were
added to determine the limiting nutrients relative to growth
potential. Results of these tests are given in Table 8. Maximum
standing crop (MSC) algal dry weight from these stations ranged
from 2.95 to 5.92 mg/1. Algal dry weights in excess of 6 mg/1
11

-------
(Miller, 1974 (3)) to 10 mg/1 (EPA, 1975 (4)) are considered to be
associated with highly productive waters which may be associated
with algal blooms.
Nutrient limitation studies conducted on these samples
indicate that nitrogen was the limiting nutrient (Table 8). With
nitrogen stimulation MSC in the range of 17 to 41 mg/1 could be
achieved. Phosphorous additions made no increase in MSC.
Dissolved Oxygen Dynamics
Recording dissolved oxygen, conductivity, pH and temperature
instrumentation (Datasondes) were deployed at mid-depth at the five
locations given in Table 1 and shown on Figure 3. The instruments
were positioned near the current meters and were deployed to
measure and record the aforementioned parameters at 30 minute
intervals from 1200 on 5/8 to 0800 on 5/10. These data are
presented in Figures 20-25 and in tabular form in Appendix E.
Dissolved oxygen levels (Figures 20-25) remained at or above 6.0
mg/1 during the study. Water column respiration rate measurements,
conducted by the dark bottle technique, indicate that very little
respiration is occurring within the water column (Table 9) . Any
fluctuations in the diurnal dissolved oxygen curves that may be
associated with water column production and respiration appear to
be masked by tidally driven water exchange.
Salinity ranges (Figure 25) reflect the location of the sonde
units in the study area with the largest salinity range experienced
at the most seaward location (SW-5). All salinity values remained
12

-------
less than 5 PPT. Temperature and pH data were also well within
norms for these estuarine waters.
Reaeration Estimates
Reaeration estimates were developed by the use of the floating
dome method, with procedures described by C.A.S. Hall (5). In this
method, a floating dome is used to measure the diffusion of oxygen
across the air/water interface. The exchange rate measured with the
floating dome can then be adjusted with the DO deficit between the
dome and the water column to provide an estimate of reaeration.
Diffusion rate experiments were conducted during the period of
1800 5/8 to 1800 5/9. During this time sequence the diffusion dome
was positioned on a pier near the aforementioned wind meter and
tide recorder (Figure 3). Dissolved oxygen levels and temperature
within the dome and the water column were recorded at 5 minute
intervals (Appendix 10). Based on these measurements a diffusion
rate of 2.86 mg/l/day was calculated (Figure 26). Coupling this
diffusion rate with the dissolved oxygen deficit corresponds to a
calculated reaeration rate coefficient (Ka) of 0.74 1/day.
Comparisons of this reaeration rate to those developed through
empirical equations (EPA, 1985 (6)) are shown on Table 10.
Reaeration rate coefficients calculated from these empirical
equations, are based on recorded wind speeds, tidal velocities and
system geometry. As shown on this Table, the predicted reaeration
rate coefficients agree closely with the rate measured by the
diffusion dome.

(2) use a different diffuser design with strongly reduced spacing to
ensure a more uniform mixed plume condition in the near-field.
Ri_..J.NDER: The user must take note that HYDRODYNAMIC MODELING by any known
technique is NOT AN EXACT SCIENCE.
Extensive comparison with field and laboratory data has shown that the
CORMIX predictions on dilutions and concentrations (with associated
plume geometries) are reliable for the majority of cases and are accurate
to within about +-50% (standard deviation).
As a further safeguard, CORMIX will not give predictions whenever it judges
the design configuration as highly complex and uncertain for prediction.

END OF MOD261: PASSIVE AMBIENT MIXING IN UNIFORM AMBIENT
** WARNING ** Because of the VERY LARGE SPACING between adjacent
risers/nozzles/ports, the above results will be UNRELIABLE
IN THE NEAR-FIELD of the diffuser.
Rather, use of CORMIX1 IS RECOMMENDED to predict the behavior for
any one of the individual jets/plumes in the initial region
before merging.

This flow configuration applies to a layer corresponding to the full water
depth at the discharge site.
Applicable layer depth = water depth =	2m
MIXING ZONE EVALUATION (hydrodynamic and regulatory summary):
X-Y-Z Coordinate system:
Origin is located at the bottom below the port center:
1000 m from the left bank/shore.
^.amber of display steps NSTEP = 20 per module.
NEAR-FIELD REGION (NFR) CONDITIONS
-------
Note: The NFR is the zone of strong initial mixing. It has no regulatory-
implication. However, this information may be useful for the discharge
designer because the mixing in the NFR is usually sensitive to the
'scharge design conditions.
jllutant concentration at edge of NFR =	4.0165 PPB
Dilution at edge of NFR	=	236.5
NFR Location:	x =	82.50 m
(centerline coordinates)	y =	.00 m
z =	2.00m
NFR plume dimensions:	half-width =	66.00 m
thickness =	2.00 m
Buoyancy assessment:
The effluent density is equal or about about equal to the surrounding
ambient water density at the discharge level.
Therefore, the effluent behaves essentially as NEUTRALLY BUOYANT.
Near-field instability behavior:
The diffuser flow will experience instabilities with full vertical mixing
in the near-field.
There may be benthic impact of high pollutant concentrations.
-FIELD MIXING SUMMARY:
_ume becomes vertically fully mixed ALREADY IN NEAR-FIELD at	82.50 m
downstream and continues as vertically mixed into the far-field.
TOXIC DILUTION ZONE SUMMARY
No TDZ was specified for this simulation.
~	REGULATORY MIXING ZONE SUMMARY +	+
No RMZ and no ambient water quality standard have been specified.
********************* final design advice and comments **********************
CORMIX2 uses the TWO-DIMENSIONAL SLOT DIFFUSER CONCEPT to represent
the actual three-dimensional diffuser geometry. Thus, it approximates
the details of the merging process of the individual jets from each
port/nozzle.
In the present design, the spacing between adjacent ports/nozzles (or
riser assemblies) is considerably larger (more than ten times) than the
local water depth. Therefore, very little interaction between adjacent
jets/plumes will occur except at considerable downstream distances.
CORMIX2 does NOT appear APPLICABLE for this discharge geometry (except
possibly at large distances in the far-field).
u..u.ess such far-field predictions are desired, the user is advised to
(1) disregard the present analysis, and to use instead CORMIX1 for the
analysis of the individual non-interacting jets/plumes from each

M' ~NG ZONE EVALUATION (hydrodynamic and regulatory summary):
X-Y-Z Coordinate system:
Origin is located at the bottom below the port center:
1000 m from the left bank/shore.
Number of display steps NSTEP = 20 per module.
NEAR-FIELD REGION (NFR) CONDITIONS :
Note: The NFR is the zone of strong initial mixing. It has no regulatory
implication. However, this information may be useful for the discharge
designer because the mixing in the NFR is usually sensitive to the
discharge design conditions.
Pollutant concentration at edge of NFR =	198.5484 PPB
Dilution at edge of NFR	=	4.7
NFR Location:	x =	2.74 m
(centerline coordinates)	y =	.00 m
z =	,00m
NFR plume dimensions:	half-width =	.82 m
thickness =	.82 m
b__yancy assessment:
The effluent density is equal or about about equal to the surrounding
ambient water density at the discharge level.
-------
Therefore, the effluent behaves essentially as NEUTRALLY BUOYANT.
Benthic attachment:
r the present combination of discharge and ambient conditions, the
scharge plume becomes attached to the channel bottom within the NFR
immediately following the efflux. High benthic concentrations may occur.
FAR-FIELD MIXING SUMMARY:
Plume becomes vertically fully mixed at	602.60 m downstream.

MIXING ZONE EVALUATION (hydrodynamic and regulatory surnmary)
-------
X-Y-Z Coordinate system:
Origin is located at the bottom below the port center-.
1000 m from the left bank/shore,
nber of display steps NSTEP = 20 per module.
NEAR-FIELD REGION (NFR) CONDITIONS :
Note: The NFR is the zone of strong initial mixing. It has no regulatory
implication. However, this information may be useful for the discharge
designer because the mixing in the NFR is usually sensitive to the
discharge design conditions.
Pollutant concentration at edge of NFR =	2.0082 PPB
Dilution at edge of NFR	=	473.0
NFR Location:	x =	82.50 m
(centerline coordinates)	y =	.00 m
z =	2.00m
NFR plume dimensions:	half-width =	66.00 m
thickness =	2.00 m
Buoyancy assessment:
The effluent density is equal or about about equal to the surrounding
ambient water density at the discharge level.
Therefore, the effluent behaves essentially as NEUTRALLY BUOYANT.
K field instability behavior:
The diffuser flow will experience instabilities with full vertical mixing
in the near-field.
There may be benthic impact of high pollutant concentrations.
FAR-FIELD MIXING SUMMARY:
Plume becomes vertically fully mixed ALREADY IN NEAR-FIELD at	82.50 m
downstream and continues as vertically mixed into the far-field.
UNSTEADY TIDAL ASSESSMENT:
Because of the unsteadiness of the ambient current during the tidal
reversal, CORMIX predictions have been TERMINATED at:
x =	1742.52 m
y =	,00m
z =	2.00m
For this condition AFTER TIDAL REVERSAL, mixed water from the previous
half-cycle becomes re-entrained into the near field of the discharge,
increasing pollutant concentrations compared to steady-state predictions.
">ool of mixed water formed at slack tide will be advected downstream
_.i this phase.
* TOXIC DILUTION ZONE SUMMARY
No TDZ was specified for this simulation.

********************** REGULATORY MIXING ZONE SUMMARY ***********************
No RMZ and no ambient water quality standard have been specified.
********************* FINAL DESIGN ADVICE AND COMMENTS **********************
C TX2 uses the TWO-DIMENSIONAL SLOT DIFFUSER CONCEPT to represent
.e actual three-dimensional diffuser geometry. Thus, it approximates
the details of the merging process of the individual jets from each
port/nozzle.
In the present design, the spacing between adjacent ports/nozzles (or
riser assemblies) is considerably larger (more than ten times) than the
local water depth. Therefore, very little interaction between adjacent
jets/plumes will occur except at considerable downstream distances.
C0RMIX2 does NOT appear APPLICABLE for this discharge geometry (except
possibly at large distances in the far-field).
Unless such far-field predictions are desired, the user is advised to
(1)	disregard the present analysis, and to use instead CORMIX1 for the
analysis of the individual non-interacting jets/plumes from each
discharge port/nozzle, or
(2)	use a different diffuser design with strongly reduced spacing to
ensure a more uniform mixed plume condition in the near-field.
P NDER: The user must take note that HYDRODYNAMIC MODELING by any known
,chnique is NOT AN EXACT SCIENCE.
Extensive comparison with field and laboratory data has shown that the
CORMIX predictions on dilutions and concentrations (with associated
plume geometries) are reliable for the majority of cases and are accurate
to within about +-50% (standard deviation).
As a further safeguard, CORMIX will not give predictions whenever it judges
the design configuration as highly complex and uncertain for prediction.

N^R-FIELD REGION (NFR) CONDITIONS :
: The NFR is the zone of strong initial mixing. It has no regulatory
implication. However, this information may be useful for the discharge
designer because the mixing in the NFR is usually sensitive to the
discharge design conditions.
-------
Pollutant concentration at edge of NFR =	99.2740 PPB
Dilution at edge of NFR	=	9.5
NFR Location:	x =	2.74 m
(centerline coordinates)	y =	.00 m
z =	.00m
NFR plume dimensions:	half-width =	.82 m
thickness =	.82 m
Buoyancy assessment:
The effluent density is equal or about about equal to the surrounding
ambient water density at the discharge level.
Therefore, the effluent behaves essentially as NEUTRALLY BUOYANT.
Benthic attachment:
For the present combination of discharge and ambient conditions, the
discharge plume becomes attached to the channel bottom within the NFR
immediately following the efflux. High benthic concentrations may occur.
FAR-FIELD MIXING SUMMARY:
Plume becomes vertically fully mixed at	602.60 m downstream.
UNSTEADY TIDAL ASSESSMENT:
cause of the unsteadiness of the ambient current during the tidal
reversal, CORMIX predictions have been TERMINATED at:
x =	1749 .20 m
y =	.00m
z =	,00m
For this condition AFTER TIDAL REVERSAL, mixed water from the previous
half-cycle becomes re-entrained into the near field of the discharge,
increasing pollutant concentrations compared to steady-state predictions.
A pool of mixed water formed at slack tide will be advected downstream
in this phase.
************************ TOXIC DILUTION ZONE SUMMARY ************************
No TDZ was specified for this simulation.
********************** REGULATORY MIXING ZONE SUMMARY ***********************
No RMZ and no ambient water quality standard have been specified.
********************* FINAL DESIGN ADVICE AND COMMENTS **********************
REMINDER: The user must take note that HYDRODYNAMIC MODELING by any known
technique is NOT AN EXACT SCIENCE.
Extensive comparison with field and laboratory data has shown that the
~ORMIX predictions on dilutions and concentrations (with associated
.ume geometries) are reliable for the majority of cases and are accurate
to within about +-50% (standard deviation).
As a further safeguard, CORMIX will not give predictions whenever it judges
the design configuration as highly complex and uncertain for prediction.
