Computers: Water Resources Models in Latin America
Ninety-six national institutions dealing with planning, irrigation, water supply, and hydropower generation in twenty-six Latin American and Caribbean countries were surveyed between February...
Hydrological Database Management
Development of hydrological database management is investigated in this study. Lotus 1-2-3, a commercially available database, which makes use of spreadsheet has been used to solve a broad...
Automated Data Collection for Reservoir Regulation
Various regulation changes in the Lake Winnebago basin have been proposed regarding the protection of wetlands and assurance of adequate outflows for water quality. To implement these...
Successive Application of Reservoir Simulation Models--A Case Study
Replacement of the conventional method of generating hydrology by a well established reservoir simulation model renders enormous amounts of flexibility and savings in computation time....
Data Transforms on USGS Surface Water Records
Surface water records compiled and stored by the United States Geological Survey (USGS) on machine readable tape are transformed and analyzed by computer methods to enable visual inspection...
Real-Time Data Verification
Recent improvements in the real-time acquisition of hydro-meteorological data have raised concerns regarding the quality of the data received. Water users having practically instant access...
Forecasting Demand for Urban Water
The purpose of this study is to assess current water use forecasting practice in the US Army Corps of Engineers and to recommend additional approaches which best satisfy current requirements....
The ADP Problems of a River Basin Commission
The Susquehanna River Basin Commission is an independent governmental agency that recently acquired its first in-house minicomputer system. The staff usage of this system has created two...
Hydrograph Decomposition: Using a Technical Database
Trouble shooting for infiltration/inflow (I/I) problems in a sewer system is made much easier with the aid of a computerized hydrograph decomposition methodology. A methodology has been...
Conjunctive Use/Sustained Groundwater Yield Design
Assuring the sustained availability of groundwater from all parts of an aquifer system is analagous to assuring that the potentiometric surface does not change over the long term. Such...
A Computer Aided Approach to Missing Time-Series Data Replacement
The objective of this research is to design, construct, and demonstrate a computer utility which will interactively aid the time series researcher in choosing an appropriate missing data...
Variable Leachate Treatment System: A Cast Study
This paper explores the experience of the authors in collecting data and designing leachate collection and treatment facilities at municipal sanitary landfills over the last several years....
A Stepwise Approach to Environmental Systems Maintenance Management
This paper provides a systematic approach to establishing a maintenance management program for environmental infrastructure. It begins by discussing the definition of program objectives,...
Metal Contamination of Sludge by Water Supply Systems
The authors present a cursory review of the source of metals in sewage sludge and an analysis of limited sludge metal data and drinking water data that supports the hypothesis that a water...
Conveyance Losses Due to Reservoir Releases
Three natural streams in Wyoming were studied in order to estimate incremental conveyance losses associated with incremental increases in stream flow. For each study area, all surface...
Predicting Quality for Drainage Water Management
In 1982, 405 measurements of the subsurface drainage water quality parameter electrical conductivity (EC) in ds/m were collected. The data were obtained from 15 subsurface drains on 23...
Daily Weather Forecasts Used to Manage Soil-Water
This paper describes a newly developed method for analyzing the rainfall probability data included in daily weather forecasts issued by the National Weather Service. The purpose is to...
Monitoring the Chesapeake Bay Fish Spawning Grounds with Aerostats and Remote Sensing Equipment
A brief review is given of the effects of acid rain and other pollutants on the fish spawning grounds in the Chesapeake Bay area. Given the need for improved monitoring of the Bay and...
