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...

Numerical Model Development for Oil Spill Dispersion into the Marine Environment
A 3-D oil spill model was developed to study the behaviour of heavy spilled oil in the sea. The model could describe the behaviour on the spilled oil on the sea surface, throughout the...
