Verification of Local Modes in a Two-Dimensional Tidal Model
Based on a generalized model equation, a two-dimensional hybrid finite element model has been developed to study tidal waves of incompressible, homogeneous fluid in rotational flows. In...
SWMM Application in Indian River County, Florida
The EPA's Storm Water Management Model (SWMM) was used to simulate drainage canal system network within Indian River County, Florida. Runoff and Extran module of the PCSWMM...
The Colorado River Simulation System
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....
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...
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...
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....
Model Study of Potential Debris Problems at the Proposed Diversion of Clover Fork River, Harlan, Kentucky
A study was conducted at the Waterways Experiment Station in Vicksburg, Mississippi, using a physical and a numerical model, to evaluate the entrance conditions at a proposed tunnel diversion...
Prediction Using Geostatistics and Mathematical Models
This paper discusses a new interpretation of geostatistical estimation and presents some thoughts on the meaning of probabilities in geostatistics and the role of mathematical models of...
GEOPACK: A Geostatistical Software System
A comprehensive, user-friendly geostatistical software system called GEOPACK has been developed. The purpose of this software is to make available the programs necessary to undertake a...
Design of Expansions for Sub-Critical Open Channel Flow
Expansions for open channel flow at sub-critical velocity are required whenever it is necessary to reduce the velocity of flow from a structure which discharges into an erodible channel....
Cocohatchee River Basin Study
The report presents the modeling of the Cocohatchee River basin, including 2-D routings for wetland regimes, hydrologic/hydraulic analyses of the agricultural and suburban land uses, and...
Optimal Reliability Based Design for Water Distribution Systems
The methodology presented in this paper explicitly includes availability measures that incorporate both mechanical and hydraulic unavailability of system components for a dynamic system....
Borden Field Data and Multivariate Geostatistics
A large-scale field experiment on natural gradient transport of solutes in groundwater was conducted in an unconfined sand aquifer in Borden, Ontario by extensive monitoring after the...
Conditional Simulation of the Wilmington Sand-Shale Sequence, Los Angeles Basin
In shaly clastic reservoirs at a scale where vertical cross flow cannot be ignored the main source of heterogeneity is the apparent random geometry of the sand-shale sequence. That geometry...
Extraction of Terrain Features from Digital Elevation Models
Digital elevation models (DEMs) are being used to determine variable inputs for hydrologic models in the Delaware River basin. Recently developed software for analysis of DEMs has been...
Geographic Information System/Watershed Model Interface
Geographic information systems allow for the interactive analysis of spatial data related to water-resources investigations. A conceptual design for an interface between a geographic information...
Scale Effects at Intakes Due to Boundary Layer Growth
Boundary layer development in hydraulic models of intakes based on Froude criteria can be poorly scaled because it is viscosity dependent. The potential for scale effects can be estimated...
Self-Aerating Spillway Flow
The concept upon which most past analyses are based is that a continuum exists in aerated flow from 100 percent water, to air bubbles in water, to a water-air mixture, to an air-water...
Sediment Basin Design Using 2-D Techniques
A set of procedures for the design of sediment basins is outlined; it is based on two-dimensional hydrodynamic analyses, in contrast to conversional practice which has used only one-dimensional...
