Kings Bay Channel Expansion Hybrid Model Assessment
A hybrid modeling system (coupled physical and numerical models) was developed to assess velocity and sediment impacts associated with channel expansion. Physical model tides and velocities...

A Modular Visual Interface for Computational Fluids Forecasting
A forecasting system is under development for predicting the three-dimensional physical features (e.g. velocity, temperature etc.) of large water bodies. Visualization and interface development...

Visualization of Grids and Flow Fields for CFD Data
This paper will address visualization of grids and flow fields for computational field simulation. Specifically, we will present results and demonstrations of surface and grid generation...

Redondo Beach Thermal Study
Thermal tests were conducted in a 3D physical model of Redondo Beach King Harbor to simulate power plant cooling water intake and discharge into the harbor. Tests were conducted to determine...

Design of a Stratified Cooling Channel
Cooling ponds are used for managing waste heat discharges. Cooling ponds are, however, expensive to construct and operate. A cooling channel is studied as an alternative means of managing...

Verification of a Three-Dimensional Numerical Hydrodynamic Model of the C&D Canal and Adjacent Estuaries
A 3D hydrodynamic model of the C&D Canal and adjacent estuaries was developed by using the WES-CH3D code. CH3D uses a simplified second order vertical turbulence model based on...

A Microcomputer-Based System for Two-Dimensional Flow Modeling
An integrated, microcomputer-based system has been developed for simulation of two-dimensional, unsteady, free surface flows. The system consists of a finite-element mesh generation code,...

Set-Down in a Tidal Embayment
A mean water level in tidal bays and estuaries that is higher than the ocean mean water level (set-up) is a fairly common occurrence. Set-down of the mean water level can be shown to be...

Model Study of an Intake Structure
To increase the delivery capacity of an existing gravity-feed water supply pipeline in Orange County, California, modification of the existing structure and placement of a booster pumping...

Physical Model of a Floating Trash Boom to Control Aquatic Weeds at the TVA Widows Creek Fossil Plant
The Tennessee Valley Authority (TVA) Widows Creek Fossil Plant seasonally encounters adverse accumulations of aquatic weeds at the intakes of the condenser cooling water pumps. To reduce...

Experimental Model Study of Over and Under Baffles
A hydraulic model study of a chlorine mixing channel was conducted at the Hydraulic Research Laboratory of the City of Los Angeles. An arrangement of over-under baffles was used to facilitate...

Application of a 2-D Water Quality Model (BETTER) to Manage Effects of Low Flow and Wastewater Effluents in Cheatham Lake, Tennessee
Applications of BETTER, a 2-D reservoir water quality model, have been made by the Nashville District Corps of Engineers (Corps) and by the Nashville Metropolitan Water and Sewerage Services...

Modelling Longitudinal Temperature Distribution in TVA Reservoir System
A one-dimensional model has been developed for computation of water temperature in the TVA reservoir system. The model has been successfully used in evaluating the impact of incremental...

A Review of Modeling and Analysis Approaches for Optimization of Reservoir System Operations
Numerous mathematical models have been developed for sizing reservoir storage capacities and establishing operating policies during project planning, for reevaluating the operating policies...

Application of a Generalized Risk Dynamic Model to a Spillway Design Flood
Risk analysis can provide a logical basis for selecting the optimal design capacity of a flow conveyance hydraulic structure for the least total cost or specified non-exceeding risk levels....

Visualization of a 3D Model of Chesapeake Bay
A three-dimensional (3D) numerical hydrodynamic and water quality model (WQM) of the Chesapeake Bay and its major tributaries has been developed by the US Army Engineer Waterways Experiment...

Visualization of a Groundwater Contaminant Model
Groundwater contamination is a problem of major national concern. Three-dimensional characterization of groundwater contamination is typically required. This paper describes integration...

Visualizing Groundwater Flow
This presentation demonstrates the application of some public domain scientific visualization software tools in the area of groundwater modeling. Specifically, we use these tools to interpret...

A Three-Dimensional Natural Resource Damage Assessment and Coupled Geographical Information System
A numerical model for natural resource damage assessments is discussed. The model addresses a wide range of spatial and temporal scales. The transport equations for both pollutant and...

An Integrated Model for Fate and Transport of Oil in Rivers
An integrated oil spill model for microcomputers is developed for simulating fate and transport of spilled oil in rivers. This model can simulate the oil slick transformation in transient...
