Genetic Algorithms in Groundwater Management
The aim of this paper is to examine applicability of genetic algorithms in groundwater planning and management. A brief description of genetic algorithms and the associated advantages...
Threshold Precipitation Events and Groundwater Recharge
Data from two study sites on the Nevada Test Site, Nevada are used with precipitation data from other long-term precipitation gages to identify the frequency of precipitation events that...
Estimation of Field Site Flow Parameters
The paper reports on the use of Kriging to obtain estimates of hydraulic conductivity underneath a rapid infiltration site. The parameters obtained were used in a two-dimensional groundwater...
Groundwater Development and Related Issues
Optimum development and management of ground water resources requires consideration of all elements of the groundwater system and their inter-relations with total hydrologic cycle along...
An Attempt of an Aquifer Model with Lack of Data
The University of the Americas in Cholula, Puebla, Mexico withdraws water from an unconfined aquifer. Also the city of Cholula and the city of Puebla withdraw water too. A model aquifer...
Movement of Colloids Under Hydraulic Gradients
A model was developed for analyzing the movement of colloidal clay particles in laboratory soil columns. The physical mechanisms of detachment of particles from the soil matrix, their...
Development of Transport Model for Groundwater Planning and Management in Taipei Basin
The objective of this paper is to develop a groundwater model for contaminant transport simulation. The transport model, in conjunction with the previously developed flow model, is used...
Mixing of Thermal Discharges at Low Froude Numbers
A study was performed to develop an optimum configuration for the discharge canal of a cooling lake. The objective was to minimize the initial mixing at the end of the discharge canal,...
1993 Ground-Water Flooding in the Havana Area
The Havana area in Mason County, west-central Illinois, experienced nearly continuous rises in the water table beginning in the fall of 1992 which created lakes in depressed areas. Water...
Modeling Hydrologic and Pollutant Transport Processes for Stromwater Runoff to Surface Waters
Combined sewer overflows and stormwater discharges, which are considered point sources, and certain nonpoint sources (NPSs) display the characteristics of precipitation-driven events....
General Urban Runoff Model for Water Quality Investigations
This paper presents and examines a general urban runoff model appropriate for water quality studies. The model is applied to separate runoff source areas and the outfall conditions are...
Coping with EPA's Transportation Storm Water Permit
EPA has released NPDES storm water monitoring data from group applicants. This paper will analyze the data to determine which pollutants are present in storm water runoff from transportation...
NPDES Storm Water Permit Compliance at Air Force Installations
Recent changes to the National Pollutant Discharge Elimination System (NPDES) program require that storm water discharges associated with industrial activity be regulated under the NPDES...
Combined Stormwater Drainage and Treatment
Due to continuing public concern regarding environmental protection for the nation's waterways, new and more stringent water quality control regulations have been developed. This is most...
Costs and Benefits of Meeting the San Francisco Bay Copper Objective by Regulating Small Treatment Plants
Metals in aquatic environments, even in very small amounts, are of concern because of potential toxicity to aquatic life forms. Copper is of particular concern in the San Francisco Bay...
Development of an Experimental Watershed for Testing Nonpoint Source Pollution from Urban Runoff
The U.S. Environmental Protection Agency (EPA) National Pollution Discharge Elimination System (NPDES) stormwater regulation program prohibits non-storm water discharges into entering...
Urban Runoff Based on Land Use and Particle Size
As point sources have achieved pollution compliance, the focus of pollution abatement has shifted to nonpoint sources. New Federal regulations require wet-weather monitoring of drainage...
Non-Point Pollution Loadings and their Impacts on Tennessee Valley Reservoirs
This is a three-year study which began in March 1992. The project has focused on inflow streams entering storage projects including Douglas, Cherokee, South Holston, Watauga, Norris, Chatuge,...
Non-Point Source Pollution Reduction
The paper reports on the results of a study to determine the effectiveness of the best management practices (BMPs) for use in the Tampa Bay Watershed. The study aims to determine the efficiency,...
