|
 | Lake Washington is one of a system of three lakes located in northwestern Washington State (Figure 1 - 1). The lake provides a textbook example of eutrophication remediation through reduction of nutrient loads. The decline and recovery of the lake are the subject of a series of classic works by W. T. Edmondson, his students, and co-workers (Edmondson 1972; Edmondson and Lehman 1981; Edmondson 1991; Edmondson 1994). The description of ... |

|
| The CE-QUAL-ICM three-dimensional eutrophication model was applied to the lower, estuarine, portion of the St. Johns River, Florida. Transport processes were obtained from the Environmental Fluid Dynamics Code. Model application period was December 1996 through November 1998. The model activated 28 state variables in the water column including physical variables, three algal groups, multiple forms of carbon, nitrogen, phosphorus and silica, and dissolved oxygen. Several features were added to the ... |

|
| This report describes the development and application of a two- dimensional, depth-integrated water quality model to Florida Bay. The model includes dynamically linked components for water column transport and eutrophication processes, sediment resuspension and effects on light attenuation, benthic sediment processes and interaction with the water column, and seagrass biomass and interactions with water column and sediments. The report describes linkage to a finite-element hydrodynamic model, estimation of freshwater inflows ... |

|
| This report describes a three-dimensional hydrodynamic and water quality model study of the San Juan Bay and Estuaries system conducted to evaluate the effectiveness of various management alternatives for improving water quality. Alternatives included methods to increase flushing, reduce pollutant loadings, and combinations of the two. The CH3D-WES hydrodynamic model and the CE-QUAL-ICM water quality model were employed in the study. The models were indirectly ... |

|
| Several numerical models (CH3D-WES, MDFATE, STFATE, SURGE, and CEQUAL-ICM) have been employed to provide information on potential losses of dredged material proposed to be placed at Site 104 in the Upper Chesapeake Bay and on potential water quality impacts. Placement of the material was assumed to either be from bottom-releasing barges or from hydraulic pump out from a barge with the material released near the bottom. ... |

|
| This report describes the plans and specifications for a Florida Bay water quality model and provides tasks and schedules for its development and application. The model is required to address issues pertaining to nutrient inputs and associated impacts on water quality and sea grass, particularly as related to changes in freshwater inflows from south Florida through the Everglades and the Central and South Florida Flood Control Project. Modeling components discussed ... |

|
| The Passaic River and Newark Bay form part of the complex New York- New Jersey harbor system. A diversion tunnel has been proposed to alleviate flooding in the upper portion of the Passaic River basin. The tunnel will divert flow from the headwaters of the Passaic directly to the upper end of Newark Bay. The objective of the study is to provide information required to evaluate the effect of the ... |

|
| CE-QUAL-ICM (Release 1.0) is a three-dimensional, time-variable eutrophication model. CE-QUAL-ICM incorporates 22 state variables that include physical properties; multiple forms of algae, carbon, nitrogen, phosphorus, and silica; and dissolved oxygen. The model incorporates a predictive submodel of benthic processes including sediment oxygen demand and sediment-water nutrient flux. Features of the model include the following: operational in one-, two, or three-dimensional configurations; state variables may be individually activated or deactivated; computations ... |

|
| A three-dimensional, time-variable, eutrophication model, CE-QUAL- ICM, was applied to Chesapeake Bay. The model incorporated 22 state variables that included physical properties, multiple forms of algae, carbon, nitrogen, phosphorus, and silica, and dissolved oxygen. The model was part of a larger package that included a three-dimensional hydrodynamic model and a benthic sediment diagenesis model. The model was initially applied to a 3-year period, 1984-1986. The model successfully simulated water-column and ... |

| Indian River and Rehoboth Bay are two shallow bodies that form part of the Delaware Inland Bays system. The Bays are subject to eutrophication problems that accompany agricultural, commercial, and recreational development in the coastal zone. A hydrodynamic/water quality model package was applied to provide a management tool to address eutrophication issues in the two Inland Bays. The CH3D hydrodynamic model simulated transport in Indian River/Rehoboth Bay for 3 years: ... |
