Real-Time Flood Forecasting on Small Computers
A real-time, rainfall-runoff, flood forecast model, developed by the Corps of Engineers Hydrologic Engineering Center (HEC), was applied to two of tributary basins in the Ohio River System....
Using Remotely Sensed Data to Estimate Runoff
The paper reports on a study to conduct numerical experiments to simulate runoff from watersheds by using remotely sensed data and hydrologic models. Data from the Sugar Creek Watershed...
Control of Select Priority Pollutants in Stormwater
A simulation program to generate the runoff quantity and quality for each storm event over a 5 year period was written. Chemical loading rate data from highways was used. Runoff was considered...
Suspended Sediment Transport from Nonpoint Sources
Precipitation, runoff, and suspended sediment concentration data were collected in a predominantly agricultural watershed in southwestern Illinois from January 1982 through October 1984....
LANDSAT and Micro-GIS for Watershed Modeling
A microcomputer-based Geographic Information System (GIS) incorporating LANDSAT or other remotely sensed digital data greatly reduces the cost of watershed modeling. The computation of...
Numerical Models for Two-Dimensional Surface Runoff
Numerical models for surface runoff in watersheds having two-dimensional or horizontally varying topography are presented. Two finite element methodologies, a standard Galerkin and a streamline...
A Hydrologic Model Developed for Microcomputers
An event oriented hydrologic catchment model has been programmed for use on a microcomputer. Because the program is written in PASCAL, it uses features of this language that eliminate...
Microcomputer Applications in Flood Management
Historically Salt Lake City has been subject to flooding from spring snow melt runoffs. Even though the volume and the rate of runoffs were similar during both years, the 1984 runoff created...
Applications of Discrete-Element Computational Models to Transient, Multi-Dimensional Problems in Hydrology
The direct computer simulation technique, discrete-element method (DEM) was applied in the development of transient, multi-dimensional mathematical models for simulating hydrologic conditions...
Time and Space Resolution for Continuous, Dynamic Storm and Runoff Model Studies
Continuous modelling correctly reproduces start-up values of storages and loss rates and statistics for properties of hydrographs. Kinematics of storms should be considered. The effects...
An Infiltration Based Runoff Model For Use With a Design Store
The feasibility of using an infiltration approach for routine runoff prediction has become a reality with the development of approximate infiltration models based on physical principles...
Urban Hydrology for Small Watersheds (TR-55 Rev.)
A microcomputer program is being prepared for the upcoming revision of the Soil Conservation Service's 'Urban Hydrology for Small Watersheds,' Technical...
SCS User-Defined Storm Hydrograph (SCS-USH)
The Soil Conservation Service User-Defined Storm Hydrograph (SCS-USH) has been developed to provide engineers and regulatory officials with a simple microcomputer tool for defining design...
A Quick Micro-Computer Urban Runoff Model
The Penn State Direct Hydrograph Model PSDH described in this paper uses watershed and rainfall data to generate a synthetic unit hydrograph and a runoff hydrograph, both gamma-distributed....
Flood Peak Program for Urbanizing Semi-Arid Areas
This paper describes a microcomputer program for flood peak determination based on a highly modified version of the Rational method developed by M. E. Zeller, which employs the Soil Conservation...
Drainage Tunnels Save Freeway Link
A 15 mile section through downtown Phoenix will complete Interstate 10. After years of delay, the project is now close to completion. The project required construction of 6.5 miles of...
Batang Ai?Transition Zone
The Batang Ai Dam in Sarawak includes two concrete faced rockfill embankments. The transition zone between the concrete face and the rockfill consisted of natural river gravels but some...
It? Dam?Selection of Type
This paper describes the studies carried out for the type of dam selection for the Ita Hydroelectric Project. Drastic rainfall conditions, large river diversion flows and an abundance...
Development of Flood Peak Regression Equatins for Small Watersheds in Southwest Florida
Hydrologic investigations were performed on the Belle Meade-Royal Palm Hammock area in Collier County, Florida. The study area, encompassing approximately 79 square miles (205 km**2),...
Accounting for CADD Center Costs
The purpose of developing a CADD cost center is to segregate all costs related to the CADD operation so that you may receive fair compensation for CADD usage and to ensure fair charges...
