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
A numerical model for simulating nitrate transport coupled to microbial activity in the saturated zone is presented. A coupled system of equations describes the transport and microbial...

Drainage of Landfill Covers and Bottom Liners
This paper presents two new tools for preliminary evaluation of drainage-system designs. The first is a set of equations that define the saturated-depth profile for steady drainage over...

Approaches for Protecting Groundwater From Agricultural Threats
In general, major groundwater pollutants contributed from agricultural sources are nitrate-nitrogen from chemical and animal fertilizers and pesticides applied on farm products for pest,...

An Interactive Microcomputer Program for One-Dimensional Solute Transport in Saturated Soil-Water Systems
This paper presents a user-friendly microcomputer program for one-dimensional solute transport in saturated soil-water systems. Eight different types of adsorption isotherms, ranging from...

Ground Water Recharge and Use, Ventura County, California
For more than 60 years United Water Conservation District and its predecessor district have recharged seven ground water basins in Ventura County, California with more than 2,500,000 acre...

Response of a Surface Aquifer to Flood Irrigation
The response of an unconfined alluvial aquifer, and associated stream system, to recharge by flood irrigation in the New Fork River valley in western Wyoming was studied. A water budget...

Perspectives on Irrigation/Drainage Education and Training
The Task Committee on Water Resources Education and Training (TCWRE) was organized in 1985 for the purpose of conducting an opinion survey to assess the adequacy of current education and...

Systems Approach for Irrigation Management of Complex Projects Involving Large Number of Farmers Under Severely Arid Regions
An Irrigation Management Information System (IMIS) was developed for complex irrigation projects involving a large number of farms under severely arid conditions. This system is a computer...
