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....

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...

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...

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...

Continued Development of the Columbia Basin Project?A Status Report
The Columbia Basin Project is located in central Washington State and encompasses approximately 1 million irrigable acres. Water from the project delivery system was first applied in 1952...

Water Erosion Prediction Project Operational Computer Program
The Water Erosion Prediction Project (WEPP) is a physically-based model to improve on-site erosion prediction techniques. It is designed to replace the Universal Soil Loss Equation (USLE)...

Proper Use of Effective Flow Boundaries
The determination of the appropriate effective flow boundaries is an important factor in the hydraulic modeling of the flow regime of a stream. It is especially critical in areas with...

Water Allocation in the Bay/Delta (California)
The California Water Resources Control Board is conducting hearings, over the period July, 1987 to 1991, to review beneficial uses of the water tributary to, within, and exported from...

Implementing a Groundwater Control Board
Memphis, Tennessee, situated on the banks of the Mississippi river, has never utilized this vast resource for water supply. Instead, Artesian wells have supplied the Memphis, Tennessee...

World Bank's Role in Global Water and Related Environmental Issues
The World Bank provides loans and technical assistance to developing countries for improvement of the physical and economic well-being of the people. A major portion of its lending is...

Estimating Impacts of Irrigation on Streamflow
This paper presents a method for estimating the impact of irrigation withdrawals on streamflows and shows the application of that method to the Kankakee River Basin of Illinois and Indiana....

Instream Flow Requirements for Riparian Vegetation
Increasing frequency of stream diversion is requiring establishment of methods to determine instream flow requirements for riparian resources. Most methods are oriented toward fisheries....

Interstate Water Management: Implications of Recent Virgina/North Carolina Conflicts
Attempts to expand the public water supply of the urbanized southeastern corner of Virginia by transferring water from an interstate river flowing from Virginia into North Carolina has...

Must the Courts Resolve All Our Conflicts?
In June 1981, the Maryland Office of Environmental Programs issued a draft 'nutrient control strategy' for the Patuxent River as a first step in preparing a regional...

Development and Application of Hydrologic Forecast Systems
Hydrologic forecast systems generally consist of several components which include computer hardware and software to perform data handling functions and enable users to calibrate hydrologic...

The Alabama Rainfall-Runoff Model, ARRM
ARRM consists of a conceptual state-space model which is cast in a stochastic framework. It uses the W.H. Green and C.A. Ampt method for infiltration, exponential decay for interflow and...

What is Necessary to Forecast River Flows Reliably?
The problem of forecasting river flows employing conceptual rainfall-runoff models is reviewed stressing the important connections that exist among data requirements, model structure,...

Channel Routing for Improved Flood Control
Lake Wappapello, located on the St. Francis River in southeastern Missouri, is operated by the St. Louis District (SLD) Corps of Engineers for purposes of flood control and recreation....

Development, Calibration and Application of Runoff Forecasting Models for the Allegheny River Basin
The computer program HEC1F, developed by the Corps of Engineers' Hydrologic Engineering Center, performs runoff forecasting. The focus of this paper is on application of HEC1F...

Operational Forecasting in Complex River Basins with SSARR-Micro Versus Mainframe Computer
The Streamflow Synthesis and Reservoir Regulation, (SSARR), model has been used for many years for river forecasting and reservoir system modeling in the Columbia River Basin. Operational...
