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....
Training Water Delivery System Operators with Simulators
A graphical display training simulator has been developed on a microcomputer to mimic the operation of a multi-reservoir water delivery system. The simulator functions as a training device...
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...
Southeastern Drought of 1988?A Federal Perspective
The drought that has plagued the Southeastern United States for most of the 1980's is continuing in two major river basins within the geographic boundaries of the South Atlantic...
Water Management for the Future?State Perspective
The State of Georgia-Environmental Protection Division (EPD) has managed the quality of the waters of Georgia since the early 1970's. Today, the main focus of water issues...
Savannah River Basin Drought Contingency Planning
Beginning in 1986, and continuing through the present time, the worst drought in recent history created severe water shortage conditions over extensive areas of the southeastern United...
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...
Prediction of Overland Phosphorus Transport Using a Phosphorus Enrichment Ratio
The Guelph model to evaluate the effects of Agricultural Management Systems on Erosion, Sedimentation, and Phosphorus yield (GAMESP) of Rousseau et al. was used to calibrate the phosphorus...
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...
Shoreline Vegetation and Retention Basins
Erosion of exposed shorelines often introduces large quantities of sediment into the stored waters of stormwater retention basins. This additional sediment load can minimize the water...
Impact of Polders Upon Flood Stage of Atrai River
A mathematical model study, using System 11 model of the Danish Hydraulic Institute, is made to assess the impact of flood control polders upon flood level of Atrai River in Bangladesh....
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...
Irrigation and Aquifer Management in Illinois
The ground-water resources in eastern Kankakee and northern Iroquois Counties, Illinois, have been used for irrigation for over 50 years. During the drought of 1988, 131 irrigation wells...
Modeling a Multiple Well Groundwater Supply System
The paper is concerned with the simulation of existing groundwater supply systems. This encompasses the delivery of the groundwater from the wells to the water treatment plant, including...
Groundwater Protection in New York State
Groundwater protection is implemented by a variety of governmental entities. At the state level, the Departments of Environmental Conservation (DEC), and of Health (DOH) are the agencies...
Groundwater Protection?The Delaware Experience
Groundwater protection in the State of Delaware has been an evolving process requiring the planning, cooperation, and implementation of rules and regulations by several state and local...
Principles of Ground Water Strategy
The states are now preparing or adopting ground water strategies under EPA direction. State and federal initiatives are currently uncoordinated, and do not add up to a coherent program....
Modeling of Nitrate Transport Coupled Dentrification in the Saturated Zone
