MIXING ZONE SPECIFICATION:
TOXIC DILUTION ZONE (TDZ) Specifications:
Since the discharge is specified as toxic, the analysis will include
a TDZ.
The pollutant concentration at the edge of the TDZ is subject to THREE
(3) CRITERIA based on the Criterion Maximum Concentration (CMC) value:
Criterion 1: The CMC must be met within a distance of 50 times the
discharge length scale in any spatial direction.
Criterion 2: The CMC must be met within a distance of 5 times the local
water depth in any horizontal direction from the outfall.
Criterion 3: The CMC must be met within 10% of the distance from the
edge of the outfall structure to the edge of the regulatory mixing zone if
a regulatory mixing zone is specified.
Also, it is RECOMMENDED that the discharge exit velocity exceed 3 m/s.

Calculating Parameters.
FLOW PARAMETERS AND LENGTH SCALES:
Relative density differences between discharge and ambient:
Ambient density at the discharge level RHOAH0 = 1027 kg/m^3.
Vertical mean ambient density RHOAM = 1027 kg/m^3.
The effluent density (1001 kg/m^3) is less than the surrounding
ambient water density at the discharge level (1027 kg/m^3).
Therefore, the effluent is POSITIVELY BUOYANT and will tend to rise
towards the surface.
Flow bulk parameters:
Discharge volume flux Q0 = 0.0892 m^3/s.
Discharge momentum flux M0 = 0.02814 m^4/s^2.
Discharge buoyancy flux J0 = 0.022146 m^4/s^3.
Flow length scales:
Jet-to-crossflow length scale Lm = 0.56 m.
Plume-to-crossflow length scale Lb = 0.84 m.
Discharge length scale LQ = 0.5317 m.
Jet-to-plume transition length scale LM = 0.46 m.
Length scale of tidal reversal Lu = 5.54 m
Time scale of tidal reversal Tu = 0.05 hours
Minimum jet to crossflow length scale Lmin = 0.48 m
Build-up paramater f(t) = 1
Non-dimensional parameters:
Densimetric Froude number FR0 = 0.82
Jet/crossflow velocity ratio R = 1.06
Parameters for CORMIX1 have been calculated
Classifying Flows.
FLOW CLASSIFICATION:
CORMIX1 includes SIX MAJOR CLASSES of possible flow configurations:
Classes S,IS: Flows trapped in a layer within linear stratification.
Classes V,H: Near Bottom, Positively buoyant flows in a uniform density
layer.
Classes IV,IH: Near Surface, Negatively buoyant flows in a uniform
density layer.
Classes NV,NH: Near Bottom, Negatively buoyant flows in uniform density
layer.
Classes IPV,IPH: Near Surface, Positively buoyant flows in uniform
density layer.
Classes A,AI: Flows affected by dynamic bottom or surface attachment.
The NEAR FIELD FLOW will have the following features:
The discharge near-field behavior is dominated by either the positive
buoyancy of the discharge or the upward vertical orientation of the discharge
port.
There is the possibility of dynamic bottom attachment.
The following conclusion on the NEAR-FIELD FLOW CONFIGURATION applies
to a layer corresponding to the FULL WATER DEPTH at the discharge site:
*** FLOW CLASS = H2 ***
Applicable layer depth HS = 2.15 m.
Flow has been classified.

MIXING ZONE EVALUATION (hydrodynamic and regulatory summary):
-------------------------------------------------------------------
X-Y-Z Coordinate system:
Origin is located at the bottom below the port center:
9 m from the left bank/shore.
Number of display steps NSTEP = 25 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 NFR edge c = 0.0361 ppb
Dilution at edge of NFR s = 6.0
Anexos
Luz Marina Troya Pérez 170
NFR Location: x = 2.23 m
(centerline coordinates) y = -0.51 m
z = 2.15 m
NFR plume dimensions: half-width (bh) = 0.97 m
thickness (bv) = 0.97 m
Cumulative travel time: 7.3283 sec.
-------------------------------------------------------------------
Buoyancy assessment:
The effluent density is less than the surrounding ambient water
density at the discharge level.
Therefore, the effluent is POSITIVELY BUOYANT and will tend to
rise towards the surface.
-------------------------------------------------------------------
PLUME BANK CONTACT SUMMARY:
Plume in unbounded section contacts nearest bank at 43.91 m
downstream.
-------------------------------------------------------------------
UNSTEADY TIDAL ASSESSMENT:
Because of the unsteadiness of the ambient current during the tidal
reversal, CORMIX predictions have been TERMINATED at:
x = 209.09 m
y = 9 m
z = 2.15 m.
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 **********************
Recall: The TDZ corresponds to the three (3) criteria issued in the
USEPA Technical Support Document (TSD) for Water Quality-based Toxics
Control, 1991 (EPA/505/2-90-001).
Criterion maximum concentration (CMC) = 0.095 ppb
Corresponding dilution = 2.263158
The CMC was encountered at the following plume position:
Plume location: x = 0.69 m
(centerline coordinates) y = -0.38 m
z = 1.23 m
Plume dimension: half-width (bh) = 0.22 m
thickness (bv) = 0.22 m
Computed distance from port opening to CMC location = 0.95 m.
CRITERION 1: This location is within 50 times the discharge length
scale of
Lq = 0.53 m.
+++++ The discharge length scale TEST for the TDZ has been SATISFIED.
++++++
Computed horizontal distance from port opening to CMC location =
0.79 m.
CRITERION 2: This location is within 5 times the ambient water
depth of HD = 2.15 m.
++++++++ The ambient depth TEST for the TDZ has been SATISFIED.++++++++++
CRITERION 3: No RMZ has been defined. Therefore, the Regulatory
Mixing zone test for the TDZ cannot be applied.
The diffuser discharge velocity is equal to 0.32 m/s.
This is below the value of 3.0 m/s recommended in the TSD.
*** All three CMC criteria for the TDZ are SATISFIED for this discharge.
***
************** REGULATORY MIXING ZONE SUMMARY *****************
No RMZ has been specified.
However:
The CCC was encountered at the following plume position:
The CCC for the toxic pollutant was encountered at the following
plume position:
CCC = 0.025 ppb
Corresponding dilution = 8.6
Plume location: x = 37.38 m
(centerline coordinates) y = -0.51 m
z = 2.15 m
Plume dimensions: half-width (bh) = 8.53 m
thickness (bv) = 0.22 m
*************** 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 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.

********************* FLOW CLASS DESCRIPTION **********************
The following description of flow class H2 applies to the FULL WATER
DEPTH at the discharge site.
FLOW_CLASS_H2
A submerged buoyant effluent issues horizontally or
near-horizontally from the discharge point.
The discharge configuration is hydrodynamically "stable", that is
the discharge strength (measured by its momentum flux) is weak in relation
to the layer depth. The discharge buoyancy plays a minor role in this case.
The following flow zones exist:
1) Weakly deflected jet in crossflow: The flow is initially
dominated by the effluent momentum (jet-like) and is weakly deflected by
the ambient current.
2) Strongly deflected jet in crossflow: The jet has become strongly
deflected by the ambient current and is slowly rising.
3) Layer boundary approach: The bent-over submerged jet/plume approaches
the layer boundary (water surface or pycnocline). Within a short distance the
concentration distribution becomes relatively uniform across the plume width
and thickness.
*** The zones listed above constitute the NEAR-FIELD REGION in which strong
initial mixing takes place. ***
4) Buoyant spreading at layer boundary: The plume spreads laterally along
the layer boundary (surface or pycnocline) while it is being advected by the
ambient current. The plume thickness may decrease during this phase. The mixing
rate is relatively small. The plume may interact with a nearby bank or shoreline.
5) Passive ambient mixing: After some distance the background turbulence
in the ambient shear flow becomes the dominating mixing mechanism. The passive
plume is growing in depth and in width. The
plume may interact with the channel bottom and/or banks.
***Predictions will be terminated in zone 4 or 5 depending on the definitions
of the REGULATORY MIXING ZONE or the REGION OF INTEREST ***
SPECIAL CASE: If discharge is non-buoyant, then the layer boundary
buoyant spreading regime (zone 4) is absent.

This is a Deeply Submerged Discharge, where the height of the discharge
port (H0 = 0.7 m), above the bottom, does NOT Exceed one-third of the local
ambient water depth (HD = 2.15 m)
Note: For special advice on this limitation please consult Section 7.4

MIXING ZONE SPECIFICATION:
TOXIC DILUTION ZONE (TDZ) Specifications:
Since the discharge is specified as toxic, the analysis will include
a TDZ.
The pollutant concentration at the edge of the TDZ is subject to THREE
(3) CRITERIA based on the Criterion Maximum Concentration (CMC) value:
Criterion 1: The CMC must be met within a distance of 50 times the
discharge length scale in any spatial direction.
Criterion 2: The CMC must be met within a distance of 5 times the local
water depth in any horizontal direction from the outfall.
Criterion 3: The CMC must be met within 10% of the distance from the
edge of the outfall structure to the edge of the regulatory mixing zone if
a regulatory mixing zone is specified.
Also, it is RECOMMENDED that the discharge exit velocity exceed 3 m/s.
In addition, the Criterion Continuous Concentration (CCC) value
specified must be met at the edge of the Regulatory Mixing Zone if such is
specified.

Relative density differences between discharge and ambient:
Ambient density at the discharge level RHOAH0 = 1027 kg/m^3.
Vertical mean ambient density RHOAM = 1027 kg/m^3.
The effluent density (1001 kg/m^3) is less than the surrounding
ambient water density at the discharge level (1027 kg/m^3).
Therefore, the effluent is POSITIVELY BUOYANT and will tend to rise
towards the surface.
Flow bulk parameters:
Discharge volume flux Q0 = 0.0892 m^3/s.
Discharge momentum flux M0 = 0.02814 m^4/s^2.
Discharge buoyancy flux J0 = 0.022146 m^4/s^3.
Flow length scales:
Jet-to-crossflow length scale Lm = 0.56 m.
Plume-to-crossflow length scale Lb = 0.84 m.
Discharge length scale LQ = 0.5317 m.
Jet-to-plume transition length scale LM = 0.46 m.

Classifying Flows.
FLOW CLASSIFICATION:
CORMIX1 includes SIX MAJOR CLASSES of possible flow configurations:
Classes S, IS: Flows trapped in a layer within linear stratification.
Classes V,H: Near Bottom, Positively buoyant flows in a uniform density
layer.
Classes IV,IH: Near Surface, Negatively buoyant flows in a uniform
density layer.
Classes NV,NH: Near Bottom, Negatively buoyant flows in uniform density
layer.
Classes IPV,IPH: Near Surface, Positively buoyant flows in uniform
density layer.
Classes A,AI: Flows affected by dynamic bottom or surface attachment.
The NEAR FIELD FLOW will have the following features:
The discharge near-field behavior is dominated by either the positive
buoyancy of the discharge or the upward vertical orientation of the discharge
port.
There is the possibility of dynamic bottom attachment.
The following conclusion on the NEAR-FIELD FLOW CONFIGURATION applies
to a layer corresponding to the FULL WATER DEPTH at the discharge site:
*** FLOW CLASS = H2 ***
Applicable layer depth HS = 2.15 m.

******************* TOXIC DILUTION ZONE SUMMARY *******************
Recall: The TDZ corresponds to the three (3) criteria issued in the
USEPA Technical Support Document (TSD) for Water Quality-based Toxics
Control,1991 (EPA/505/2-90-001).
Criterion maximum concentration (CMC) = 1.15 ppb
Corresponding dilution = 0.652174
The CMC was encountered within a control volume describing a portion
of the discharge plume.
Therefore, the following plume conditions are a conservative
estimate (with lower concentrations or with larger dimensions) for the
region at whose boundary the CMC is met:
Local boundary concentration = 0.75 ppb
Corresponding dilution = 1
Plume location: x = 0 m
(centerline coordinates) y = 0 m
z = 0.7 m
Plume dimension: half-width (bh) = 0.3 m
thickness (bv) = 0.3 m
Computed distance from port opening to CMC location = 0 m.
CRITERION 1: This location is within 50 times the discharge length
scale of Lq = 0.53 m.
++ The discharge length scale TEST for the TDZ has been SATISFIED ++
Computed horizontal distance from port opening to CMC location =
0 m.
CRITERION 2: This location is within 5 times the ambient water
depth of HD = 2.15 m.
+++++ The ambient depth TEST for the TDZ has been SATISFIED +++++++
CRITERION 3: No RMZ has been defined. Therefore, the Regulatory
Mixing zone test for the TDZ cannot be applied.
The diffuser discharge velocity is equal to 0.32 m/s.
This is below the value of 3.0 m/s recommended in the TSD.
*** All three CMC criteria for the TDZ are SATISFIED for this discharge
***
************ REGULATORY MIXING ZONE SUMMARY *****************
No RMZ has been specified.
However:
The CCC was encountered at the following plume position:
The CCC for the toxic pollutant was encountered at the following
plume position:
CCC = 0.15 ppb
Corresponding dilution = 5.0
Plume location: x = 1.69 m
(centerline coordinates) y = -0.49 m
z = 2.15 m
Plume dimensions: half-width (bh) = 0.76 m
thickness (bv) = 0.93 m
************** 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 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.

Informe sobre la descripción del tipo de flujo (Flow Class Description)
**************** FLOW CLASS DESCRIPTION ***************
The following description of flow class H2 applies to the FULL WATER DEPTH
at the discharge site.
FLOW_CLASS_H2
A submerged buoyant effluent issues horizontally or near-horizontally
from the discharge point.
The discharge configuration is hydrodynamically "stable", that is the
discharge strength (measured by its momentum flux) is weak in relation
to the layer depth. The discharge buoyancy plays a minor role in this case.
The following flow zones exist:
1) Weakly deflected jet in crossflow: The flow is initially
dominated by the effluent momentum (jet-like) and is weakly deflected by
the ambient current.
2) Strongly deflected jet in crossflow: The jet has become
strongly deflected by the ambient current and is slowly rising.
3) Layer boundary approach: The bent-over submerged jet/plume
approaches the layer boundary (water surface or pycnocline). Within a
short distance the concentration distribution becomes relatively uniform
across the plume width and thickness.
*** The zones listed above constitute the NEAR-FIELD REGION in which
strong initial mixing takes place ***
4) Buoyant spreading at layer boundary: The plume spreads laterally
along the layer boundary (surface or pycnocline) while it is being
advected by the ambient current. The plume thickness may decrease during
this phase. The mixing rate is relatively small. The plume may interact
with a nearby bank or shoreline.
5) Passive ambient mixing: After some distance the
backgroundturbulence in the ambient shear flow becomes the dominating
mixingmechanism. The passive plume is growing in depth and in width.The
plume may interact with the channel bottom and/or banks.
*** Predictions will be terminated in zone 4 or 5 depending on the
definitions of the REGULATORY MIXING ZONE or the REGION OF INTEREST ***
SPECIAL CASE: If discharge is non-buoyant, then the layer boundary buoyant
spreading regime (zone 4) is absent.

MIXING ZONE SPECIFICATION:
TOXIC DILUTION ZONE (TDZ) Specifications:
Since the discharge is specified as toxic, the analysis will include
a TDZ.
The pollutant concentration at the edge of the TDZ is subject to
THREE (3) CRITERIA based on the Criterion Maximum Concentration (CMC)
value:
Criterion 1: The CMC must be met within a distance of 50 times the
discharge length scale in any spatial direction.
Criterion 2: The CMC must be met within a distance of 5 times the
local water depth in any horizontal direction from the outfall.
Criterion 3: The CMC must be met within 10% of the distance from
the edge of the outfall structure to the edge of the regulatory mixing
zone if a regulatory mixing zone is specified.
Also, it is RECOMMENDED that the discharge exit velocity exceed 3
m/s.
In addition, the Criterion Continuous Concentration (CCC) value
specified must be met at the edge of the Regulatory Mixing Zone if such
is specified.

Calculating Parameters.
FLOW PARAMETERS AND LENGTH SCALES:
Relative density differences between discharge and ambient:
Ambient density at the discharge level RHOAH0 = 1027 kg/m^3.
Vertical mean ambient density RHOAM = 1027 kg/m^3.
The effluent density (1001 kg/m^3)is less than the surrounding
ambient water density at the discharge level (1027 kg/m^3).
Therefore, the effluent is POSITIVELY BUOYANT and will tend to rise
towards the surface.
Flow bulk parameters:
Discharge volume flux Q0 = 0.0892 m^3/s.
Discharge momentum flux M0 = 0.02814 m^4/s^2.
Discharge buoyancy flux J0 = 0.022146 m^4/s^3.
Flow length scales:
Jet-to-crossflow length scale Lm = 0.47 m.
Plume-to-crossflow length scale Lb = 0.47 m.
Discharge length scale LQ = 0.5317 m.
Jet-to-plume transition length scale LM = 0.46 m.
Length scale of tidal reversal Lu = 6.96 m
Time scale of tidal reversal Tu = 0.08 hours
Minimum jet to crossflow length scale Lmin = 0.81 m
Build-up paramater f(t) = 0.19
Non-dimensional parameters:
Densimetric Froude number FR0 = 0.82
Jet/crossflow velocity ratio R = 0.88

Classifying Flows.
FLOW CLASSIFICATION:
CORMIX1 includes SIX MAJOR CLASSES of possible flow configurations:
Classes S,IS: Flows trapped in a layer within linear
stratification.
Classes V,H: Near Bottom, Positively buoyant flows in a uniform
density layer.
Classes IV,IH: Near Surface, Negatively buoyant flows in a uniform
density layer.
Classes NV,NH: Near Bottom, Negatively buoyant flows in uniform
density layer.
Classes IPV,IPH: Near Surface, Positively buoyant flows in uniform
density layer.
Classes A,AI : Flows affected by dynamic bottom or surface
attachment.
The NEAR FIELD FLOW will have the following features:
The discharge near-field behavior is dominated by either the
positive buoyancy of the discharge or the upward vertical orientation of
the discharge port.
There is the possibility of dynamic bottom attachment.
Because of the strong ambient current, the discharge flow will
dynamically attach to the bottom in the near-field (wake attachment).
There may be benthic impact of high pollutant concentrations.
The following conclusion on the NEAR-FIELD FLOW CONFIGURATION
applies to a layer corresponding to the FULL WATER DEPTH at the discharge
site:
*** FLOW CLASS = H1A1 ***
Applicable layer depth HS = 2.15 m.
Flow has been classified.

*******************************************************************
HYDRODYNAMIC CLASSIFICATION:
*------------------------*
| FLOW CLASS = H1A1 |
*------------------------*
This flow configuration applies to a layer corresponding to the full
water depth at the discharge site.
Applicable layer depth = water depth = 2.15 m

MIXING ZONE EVALUATION (hydrodynamic and regulatory summary):
-------------------------------------------------------------------
X-Y-Z Coordinate system:
Origin is located at the bottom below the port center:
10 m from the right bank/shore.
Number of display steps NSTEP = 10 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 NFR edge c = 0.0082 ppb
Dilution at edge of NFR s = 20.1
Anexos
Luz Marina Troya Pérez 185
NFR Location: x = 10.55 m
(centerline coordinates) y = 0.47 m
z = 2.15 m
NFR plume dimensions: half-width (bh) = 1.61 m
thickness (bv) = 1.61 m
Cumulative travel time: 26.1513 sec.
-------------------------------------------------------------------
Buoyancy assessment:
The effluent density is less than the surrounding ambient water
density at the discharge level.
Therefore, the effluent is POSITIVELY BUOYANT and will tend to rise
towards the surface.
-------------------------------------------------------------------
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 612.58 m downstream.
-------------------------------------------------------------------
PLUME BANK CONTACT SUMMARY:
Plume in unbounded section contacts nearest bank at 72.39 m
downstream.
-------------------------------------------------------------------
UNSTEADY TIDAL ASSESSMENT:
Because of the unsteadiness of the ambient current during the tidal
reversal, CORMIX predictions have been TERMINATED at:
x = 667.14 m
y = -10 m
z = 2.15 m.
For this condition BEFORE TIDAL REVERSAL, extensive re-entrainment
of previously discharged is unlikely.
To determine the minimum dilution, perform additional simulations
after slack tide.
***************** TOXIC DILUTION ZONE SUMMARY ********************
Recall: The TDZ corresponds to the three (3) criteria issued in the
USEPA Technical Support Document (TSD) for Water Quality-based Toxics
Control,1991 (EPA/505/2-90-001).
Criterion maximum concentration (CMC) = 0.095 ppb
Corresponding dilution = 1.736842
The CMC was encountered at the following plume position:
Plume location: x = 0.67 m
(centerline coordinates) y = 0.47 m
z = 0 m
Plume dimension: half-width (bh) = 0.80 m
thickness (bv) = 0.80 m
Computed distance from port opening to CMC location = 1.08 m.
CRITERION 1: This location is within 50 times the discharge length
scale of Lq = 0.53 m.
+++++ The discharge length scale TEST for the TDZ has been SATISFIED ++++++
Computed horizontal distance from port opening to CMC location =
0.82 m.
CRITERION 2: This location is within 5 times the ambient water
depth of HD = 2.15 m.
++++++ The ambient depth TEST for the TDZ has been SATISFIED ++++++
CRITERION 3: No RMZ has been defined. Therefore, the Regulatory
Mixing zone test for the TDZ cannot be applied.
The diffuser discharge velocity is equal to 0.32 m/s.
This is below the value of 3.0 m/s recommended in the TSD.
*** All three CMC criteria for the TDZ are SATISFIED for this discharge
***
****************REGULATORY MIXING ZONE SUMMARY ******************
No RMZ has been specified.
However:
The CCC was encountered at the following plume position:
The CCC for the toxic pollutant was encountered at the following
plume position:
CCC = 0.045 ppb
Corresponding dilution = 3.7
Plume location: x = 1.51 m
(centerline coordinates) y = 0.47 m
z = 0 m
Plume dimensions: half-width (bh) = 0.85 m
thickness (bv) = 0.85 m
*************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 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.

The ambient crossflow effect is strong and/or the height of the discharge
port above the bottom is too small. This leads to rapid attachment of the
discharge flow to the bottom with a recirculation wake in the lee of the
discharge structure.
Following the recirculation the discharge flow will lift off from
the bottom due to its strong buoyancy.
In the absence of wake attachment the dominant flow class would be
given by the prefix (..). You may request detailed information on that
flow class further below. Additional advice on how to prevent bottom
attachment (e.g. by increasing the height of the discharge port) will be
provided in the summary program element SUM.
The following flow zones exist:
1) Recirculation zone: The discharge flow becomes quickly deflected
by the ambient flow and attaches to the bottom. A recirculation eddy exists
in the lee of the discharge structure.
2) Lift-off: Because of the positive buoyancy the plume detaches
from the bottom and starts to rise upward.
3) Strongly deflected plume in crossflow: The plume has been
strongly deflected by the current and is slowly rising toward the surface.
4) Layer boundary approach: The bent-over submerged jet/plume
approaches the layer boundary (water surface or pycnocline). Within a
short distance the concentration distribution becomes relatively uniform
across the plume width and thickness.
*** The zones listed above constitute the NEAR-FIELD REGION in which
strong initial mixing takes place ***
5) Buoyant spreading at layer boundary: The plume spreads laterally
along the layer boundary (surface or pycnocline) while it is being
advected by the ambient current. The plume thickness may decrease during
this phase. The mixing rate is relatively small. The plume may interact
with a nearby bank or shoreline.
6) Passive ambient mixing: After some distance the background
turbulence in the ambient shear flow becomes the dominating mixing
mechanism. The passive plume is growing in depth and in width. The plume
may interact with the channel bottom and/or banks.
*** Predictions will be terminated in zone 5 or 6 depending on the
definitions of the REGULATORY MIXING ZONE or the REGION OF INTEREST ***
