General Considerations for Managing Floods and Droughts
Work described at this conference and future developmental work of water resource engineers will best contribute to professional improvement if such work is guided by appropriate objectives....
Are Soil Moisture Accounting Models Needed for the Real Time Forecasting of River Flows?
The difficulties inherent in using conceptual rainfall-runoff models in conjunction with filtering techniques, for the real time forecasting of river flows, are reviewed. The issue of...
The Great Lakes Large Basin Runoff Model
The Great Lakes Environmental Research Laboratory (GLERL) developed its Large Basin Runoff Model (LBRM) specifically for modeling runoff and moisture storages in the large river basins...
Probabilistic Forecasts of Continued High Great Lakes Water Levels
Existing projections of Great Lakes water levels over the next several years do not consider how meteorologic variability affects the hydrologic processes (basin runoff, overlake precipitation,...
Water Supply Analysis for the Milk River Basin, Montana
The U. S. Bureau of Reclamation's Milk River Irrigation Project provides water for 55,000 ha of irrigation in the Milk River basin of Montana. The project includes an interbasin...
Missouri River Basin Water Accounting System
A water accounting system was developed for the Missouri River Basin to establish an accurate and acceptable base of information describing water availability and uses, and to provide...
Optimizing a Minimum Instream Flowby
The Commonwealth of Virginia is currently investigating methods to establish minimum instream flow requirements which may be applied to flow allocations statewide. The Crump Creek Reservoir...
Alternative Formulations for Water Quality Management Models
Various model formulations for water quality management are examined herein, each of which involves a somewhat different approach to the problem of determining optimal treatment levels...
A Water Quality Model for Urbanized Drainage Basins
The Virginia Stormwater (VAST) Model has been developed for use on IBM compatible microcomputers to simulate stormwater runoff and nonpoint source pollution. Hydrologic and nonpoint source...
Water Quality Management Through Project Operation
Harry S. Truman Dam, a multipurpose reservoir project, is located on the Osage River in the headwaters of the Lake of the Ozarks. Construction of this project created the potential to...
Spatial Attenuation of Major Pennsylvania Storms
To utilize point estimates for more expansive areas, reduction factors are necessary to account for the attenuation of storm magnitude with increasing area. The spatial attenuation of...
Experiences of the U.S. Army Engineer District, Pittsburgh in Collecting Real-Time Water Control Data
As a result of an ever increasing need to optimize water use, 'Reservoir Regulation' has evolved into what is now known as 'Water Control Management'. In addition to the flood control...
The Estimation of Rainfall for Flood Forecasting Using Radar and Rain Gage Data
The use of radar-rainfall data in combination with rain gage measurements may improve rainfall estimates over those based on either form of measurement alone. A set of rainfall analysis...
Mesonets--A Solution to Improving Flood Forecasting
Floods continue to cause major destruction annually despite the efforts of Federal water resources agencies. Improved flood forecasts can reduce flood damages and corresponding loss of...
Long-Range Forecasts of Water-Supplies
Many engineers and water-users have an urgent need for reliable predictions of future rainfall and water supplies, extending many months or years ahead. Correlation of known historic rainfall...
Water Supply Demand Forecast
In this study, estimates of location, quantity and timing of water demands have been investigated for determination of the adequacy of an existing water supply system, the need for additional...
Expert System for Mixing Zone Analysis of Toxic and Conventional Discharges
The Cornell Mixing Zone Expert System (CORMIX) is a series of software subsystems for the analysis, prediction and design of aqueous toxic or conventional pollutant discharges into watercourses...
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...
Reservoir Water Quality Assessment Using in Situ Microcosms
Although there are a number of techniques for determining the limiting nutrient, as will be demonstrated, in-reservoir microcosms permit in situ experiments to be conducted under relatively...
Model Choice and Scale in Urban Drainage Design
This paper addresses the question of model choice and scale by comparing various model applications to a 95-acre gaged catchment, known as the Lake Hills watershed, in Bellevue, Washington....
