Estimation of Infiltration Rates from a Landfill
The Landfill Source Model (LSM) provides a physically-based, computationally efficient estimate of leachate emanating from a landfill. The model is PC-based and simulates a number of surface...
Transport of Injected Produced Water: A Sensitivity Study
This paper deals with the development and application of a model to assess potential environmental effects on Underground Sources of Drinking Water (USDW) due to the presence of an improperly...
An Expert System for Groundwater Management with Applications to Collier County, FL
This paper describes techniques used in frequency analysis, time series model building, forecasting, up-dating, and mapping. Domain knowledge of experts is transferred into the system...
Sensitivity of Non-Point Source Models to Net Rainfall
A sensitivity analysis of the ANSWERS model was conducted to explore the possible impact on model outputs of discretizing rainfall input data into short time increments of various durations....
A Multivariate Analysis of Stillwater Lakes, Nevada
Stillwater Lakes located in western Nevada has been experiencing an astounding number of fish and waterfowl deaths since August 1986. This problem is explored through a multivariate statistical...
Behavior of Total Zinc in the Similkameen River
Multiple linear regression analysis was used to: develop equations that summarize the relationship between total zinc and a set of water quality characteristics measured in the Similkameen...
The MSU Sprinkling Infiltrometer: A Device to Measure Time-to-Ponding
Time-to-ponding can be determined quickly and with minimal disturbance to the soil surface by the use of a sprinking infiltrometer developed at Michigan State University (MSU). Solenoid...
Drought in Tennessee: Implications on Irrigation System Capacity
Recent droughts in Tennessee have led to a study of the required irrigation system capacity for the state. Data from 1951 through 1988 were analyzed for probabilities of precipitation...
The Water Erosion Prediction Project: Erosion Processes
The erosion process on hillslopes is conceptualized in the USDA Water Erosion Prediction Project (WEPP) as being divided into rill and interrill processes. Rill detachment occurs when...
The Influence of Water Tables on Herbicide Losses
Atrazine and metolachlor were applied preemergent on April 22, 1987, to silage corn on high watertable fields which were either subsurface drained (104 mm drain tubes 1 m deep) or surface...
Computer-Aided Negotiation of Water Resources Issues in California's Central Valley Project
The U.S. Bureau of Reclamation operates the Central Valley Project (CVP) in California. The CVP is a large system of streams, reservoirs and canals in California's Sacramento and San Joaquin...
Limitations of Level-Pool Routing in Reservoirs
Storage routing is defined for purposes of this study as any routing technique which expresses reservoir storage as a single-valued function of stage, and hence it is sometimes termed...
Seasonal Streamflow Forecasts Based Upon Regression
Many western water-supply system operators employ forecasts of seasonal inflows for the snow-melt season to plan spring and summer operations. This study considers the simple statistical...
A Microcomputer Model for Integrated Analysis of Peaking Hydro in a Thermal System
An integrated approach to simulation of a hydro system called HYDROMOD has been developed and used to place a value on additional energy-limited peaking hydro capacity added to a major...
Role of Data Management in Water Control
The success of a system of software that must provide the water control user with current information, model analysis results, and forecasts of future behavior, is closely associated with...
Computer Program for Smoothing and Correcting Hourly Time Series Data
A FORTRAN computer program has been developed for the U.S. Army Corps of Engineers St. Louis District that automatically screens and corrects hourly time series data for gross errors and...
Production Scheduling Model for Hydro-Qu?bec
A deterministic optimization model is described which allows to schedule the production of a predominantly-hydroelectric power system. Demand and exogenous inflows are assumed known with...
Comprehensive Optimization Model for Hydroelectric Reservoir Operations
The Energy Management and Maintenance Analysis (EMMA) model is used to maximize net revenues to Manitoba Hydro considering the operation of hydroelectric and thermal generation, generation...
A Pilot Intelligent Decision-Support System for Reservoir Optimization
Various classes of knowledge used in reservoir design, planning and operations for improving the efficiency of the optimization processes are discussed in this paper. A prototype system...
Hydropower Stochastic Forecasting and Optimization
A microcomputer package was implemented to support real-time decisions for weekly and month-end water management at an industrial complex in the mountains of British Columbia. The rolling...
