The Colorado River Simulation System (CRSS) is a comprehensive computer tool designed to assist water resource managers in long-range planning and management of the Colorado River Basin....
An Analytical Solution to Verify a Nonlinear Tidal Circulation Model
The governing equations for this study are the shallow water equations including convective terms. Oscillations of free surface are assumed important in comparison to the total water depth....
Implementation of a Hydrodynamic Model for the Upper Potomac Estuary
A vertically integrated, two-dimensional hydrodynamic/transport model has been implemented for the upper extent of the Potomac Estuary between Indian Head and Morgantown, Md. The model...
A Branched Hydrodynamic Model of the Sacramento-San Joaquin Delta, California
A new and efficient hydrodynamic model is used to simulate flows in the Sacramento-San Joaquin Delta, California. The model solves the one-dimensional shallow water equations for flow...
An Ongoing Investigation of Residual Suspended Material Transport in Central San Francisco Bay, CA
A study of suspended material transport in San Francisco Bay, California, is presently underway by the U.S. Army Corps of Engineers. This paper describes preliminary numerical model and...
Comparison of Tenn-V and TR-55 on TVA Watersheds
The storm hydrograph simulation models TENN-V and TR-55 were compared as to their respective abilities to reproduce 468 storms observed on 54 watersheds. TR-55 did not represent the Tennessee...
Effect of Errors in Rainfall Measurements on Real-Time Forecasting Via On-Line Conceptual Models
The paper analyzes the issue of the choice between off-line and on-line use of lumped conceptual models for real-time flood forecasting. The effects of the adaptive use in the presence...
Spatial and Temporal Variations of Precipitation Effects on Storm Hydrographs
A partial area, variable source hydrologic rainfall runoff model, called MAPHYD, was developed utilizing digital maps, interactive computer graphics and several infiltration mechanisms....
Radar Rainfall Measurements and Runoff Forecasting
Rainfall varies in intensity and depth over time and space. Weather radar systems can provide estimates of rainfall at points in space with nearly continuous coverage with respect to time....
