Plans for National Flood Frequency by Microcomputer
Work is underway on a planned microcomputer program that will include about 1500 prediction equations for 214 flood regions of the United States and Puerto Rico. The program will include...
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...
Design, Construction and Testing of Repairs to the Low Level Outlets at Terzaghi Dam
Operation of the low level outlets (LLOs) at Terzaghi Dam in southwestern British Columbia resulted in severe cavitation at operating heads significantly lower than design. Modifications...
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....
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...
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....
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...
1-D and 2-D Analysis of Flood Plain Encroachment
The paper reports on a study into the effects of a local encroachment in a broad regular flood plain. The results of a one-dimensional analysis were compared with the results of an equivalent...
The Illinois GIS and Hydrologic Database
Development of the Illinois Geographic Information System (GIS) from 1983 to the present is described including the hardware configuration and ARC/INFO software. The database design at...
UNET: A Model of Unsteady Flow Through a Full Network of Open Channels
UNET is a PC-based dynamic wave, unsteady flow model for the solution of the full network problem. The program applies a linearized implicit finite difference scheme to solve the full...
Risk Assessment of System of Dams
The application of risk assessment to a series of dams on a river is presented here. A general discussion of the basic principles of risk assessment approach to dam engineering is given...
Elements of a Coastal Stormwater Drainage System
Several elements in the design of a stormwater drainage system that outfalls to the ocean are discussed. The paper discusses a study conducted of the Ocean Lakes Watershed near Myrtle...
Model for Determining the Optimal Rehabilitation and Replacement of Water Distribution System Pipes
K.E. Lansey and L.W. Mays developed a new methodology for the minimum cost design of new and expansion of existing water distribution systems. This methodology interfaces a nonlinear programming...
