ENDOW, An Expert System for Screening Environmental Features for Stream Alternations
This paper discusses development of an expert system for Environmental Design of Waterways Projects (ENDOW) by stream alteration specialists who were novices in artificial intelligence....
Stochastic Stream Flow Analysis for Hydrograph Controlled Waste Release
A risk based procedure for the design of hydrograph controlled release sewage lagoons is derived. The procedure is based on a stochastic analysis of streamflow events above a given threshold...
Maximizing Utility of Interfaces for Hydrologic Models
From the time a watershed layout has been determined, there is sufficient information for a computer to generate a command sequence for hydrologic simulation. Recognizing this fact, an...
An Urban Hydrology Model for the Personal Computer
The use of personal computers to evaluate the effects of urbanization on the hydraulic response characteristics of a watershed is discussed in this paper. Specifically, the use of a group...
Site Hydrology and Basin Design Using Spreadsheets
The Soil Cover Complex Method which was developed by the Soil Conservation Service is a commonly accepted method of evaluating site hydrology. The solution of this method is facilitated...
Micro-Illudas for Urban Drainage Design
The Illinois Urban Drainage Area Simulator (ILLUDAS) was developed at the Illinois State Water Survey in 1969 and has been available for use on mainframe computers since 1974. An enhanced...
HEC-1 and HEC-2 Applications on the Microcomputer
The Hydrologic Engineering Center (HEC) has developed versions of the HEC-1 Flood Hydrograph Package and the HEC-2 Water Surface Profiles programs for MS/PC-DOS compatible microcomputers...

Microcomputer software is now available which implements the Soil Conservation Service's recently revised 'Urban Hydrology for Small Watersheds',...
An Analytically Derived Distribution Function for Flood Volume
A general stochastic model is proposed to determine analytically the distribution function for flood volume. A flood event in this study is defined as an unbroken sequence of consecutive...
Well Field Management Designed to Miminize Impact on Surface-Water Flow
Restrictions placed on the operation of a well field used for public water supply initiated an investigation to develop management techniques that would maximize utilization of the well...
A Probabilistic Method for Determination of the Required Capacity of Reservoirs
Evaluation of water supply potential of multi-purpose dams generally involves determination of the required capacity of reservoirs for new dams and analysis of safe yield or reliable yield...
Flood Forecasting Using Local Resources
A dynamic wave flood routing computer program has been used to develop a flood forecasting model for a 5000 mi**2 watershed in lower Michigan. The modeled area covers over 200 miles of...
Real-Time Hydrologic Modeling
The Huntington District of the Corps of Engineers is currently using daily computer modeling for guidance in regulating all nine of its major river basins. Both pool elevation and flow...
Effects of Data Extension on Drought Probabilities
A condensed-parameter disaggregation model was applied to the monthly streamflow records on two rivers in Idaho, to investigate the occurrence and probabilities of drought periods. Using...
Deriving Streamflow Distribution Probabilities
Streamflow distribution probabilities are often involved in the stochastic analysis of water resources systems. Limited by data availability, certain probability terms can hardly be abstracted...
Hydrologic Runoff Modeling of Small Watersheds: The Tinflow Model
TINFLOW is a PC-based Geographic Information System (GIS) that utilizes the Triangulated Irregular Network (TIN) and associated data structures, together with a deterministic, finite difference...
A Flood Prediction Geographic Information System
The paper discusses a GIS that derives kinematic wave model parameters using stream network, elevation, and basin boundary data. Various approaches are being investigated for estimating...
Modeling Support for Stormwater Management
An innovative 'digitization' procedure has been developed and successfully utilized to accurately and economically prepare and manage the extensive amount of...
Muskingum Flow Routing Using Personal Computers
The paper discusses how tedious computations involved in flow routing can be easily implemented on Personal Computers. Parameter estimation and routing calculations for both linear and...
Utility Programs for DWOPER and DAMBRK
Time and computer resources greatly limit potential investigations and sensitivity anslyses. In order to facilitate modeling with the National Weather Service (NWS) programs DWOPER (Operational...
