A computer-based environmental planning tool, designed to help mitigate the environmental problems associated with leaking underground storage tanks (UST) is presented in this article....
Analysis of Model Uncertainty Using Bayesian Monte Carlo
Bayesian Monte Carlo analysis combines Bayesian inference with standard Monte Carlo techniques to provide improved estimates of the uncertainty in water quality model parameters and results....
Effect of Flow Conditions on Stream Reaeration Coefficients
Contrary to the findings of previous studies of channel-controlled stream reaches, it was found that, in four reaches of a small stream characterized by a series of pools and riffles,...
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....
Managing Water Shortage by Regional Cooperation and Conservation
In the New York-New Jersey metropolitan area, water emergencies becoming more frequent events because of increases in water demand and lack of new supply additions. The water supply problem...
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...
Urban Stormwater Runoff Management
Local land use regulations managing stormwater runoff in new urban developments are the most practical and effective method to control pollutants in urban stormwater runoff or prevent...
Hydrologic Methodology for Evaluating Urban Development
It is recommended that a hydrologic methodology be utilized that contains sufficient parameters to enable the user to evaluate the impact of the changes to the watershed resulting from...
Impact of Detention Storage on Main Stream Flooding
The methodology, results and management implications are presented for a stormwater study at an urban watershed experiencing periodic flooding along the main channel. Local data were collected...
Flood Warning Systems as a Means for Reducing Urban Flood Losses
This paper describes the potential effectiveness of flood warning systems in reducing loss of life. The paper describes the problems associated with urban flood warning systems (or lack...
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...
Water Resources Planning for the San Antonio Region
Water resources planning for the San Antonio region begins with the physical setting and the technical considerations - the science and engineering aspects. It proceeds to the economic...
