National Weather Service Operational River Forecasting in a UNIX Environment
The mission of the National Weather Service (NWS) includes providing river and flood forecasts and warnings for protection of life and property, and providing basic hydrologic forecast...

Snow Estimation?A GIS Application for Water Resources Forecasting
In the Western United States approximately 75 percent of the annual runoff results from snowmelt. Observations of the snow cover provide an important source of information for forecasting...

A National System for Threshold Runoff Estimation
Threshold runoff is the amount of effective (or excess) rainfall of a given duration uniformly distributed over a certain catchment that is just enough to cause flooding at the outlet...

Storm Sewer Analysis & Design Utilizing Hydrographs
In this paper a computer model, designated STORM.HYD, for the analysis and design of storm sewer systems utilizing a hydrograph procedure is presented and discussed. This model which actually...

Decision Support System for Water Supply Management
Water supply management is one area in which subjective decision making becomes necessary. Knowledge based decision support system is proposed for use in operation and management of an...

Prediction of Water Availability in River Headwaters and Control of Facility Water Demand in Response to River Flows
As part of the permitting and design of a power plant, the ability to supply cooling water subject to permit and availability constraints was investigated. As a first step, a synthetic...

Development of an Expert System for Urban Runoff
The U.S. EPA's Storm Water Management Model, SWMM, (Version 4.20, 1988) is a comprehensive water quality and quantity mathematical model for simulation of urban runoff in storm and combined...

A Sharp-Interface Salt Water Intrusion Code for Layered Aquifer Systems
This paper presents a quasi three dimensional, sharp-interface code that simulates salt water intrusion problems in layered aquifer systems. Efficient and robust numerical schemes make...

Verification Tests for Transport Modeling in Coastal Aquifers
The U.S. Geological Survey three dimensional Heat and Solute Transport (HST3D) model is used to simulate fate and transport of dissolved contaminant in coastal aquifers. The model originally...

Management of Supply Canals in a Rotation Irrigation System
Management of the water supply canals in a rotation irrigation system can affect the uniformity of water delivery to farms. Different management procedures are needed, depending on the...

Long Range Planning for System Rehabilitation and Improvement
The Turlock Irrigation District, located in the Central Valley of California, supplies irrigation water to 150,000 acres and electricity to over 60,000 customers. The District's irrigation...

Equitable Distribution of Water in a Rotation Irrigation System
'Volume-based Equity' is proposed as a means of improving the uniformity of water delivery in a rotation irrigation system. Management procedures are developed that can improve water delivery....

Computerized Maintenance Planning for Agency-Managed Irrigation Systems
Computerized maintenance planning has been established to facilitate: (1) preparation of the 'Catch-Up' Maintenance Plan using the field data collected while conducting the Diagnostic...

A Frost Protection Design for Fruit Trees in Southwest Colorado
The project explores the feasibility of producing commercial quantities of fruit in the high and arid environment of Southwestern Colorado by using low-volume water delivery systems for...

Without Water Transfers, Cities will Thirst
California will have to depend on water transfers from agricultural areas for at least the next ten years to supply water needed for increasing municipal and industrial (urban) uses. California's...

Wastewater Treatment and Disposal System for a Vegetable Processing Facility
The authors describe the implementation of a wastewater management system designed to dispose of up to 2.1 million gallons of vegetable processing wastewater generated per day at Bellingham...

Innovative Technology Enhances Water Availability for Irrigation
This paper presents an innovative technology, aquifer storage and recovery (ASR), that is capable of increasing the efficiency of existing irrigation water supply systems. An analysis...

The Role of Irrigation System Management and Performance in Facilitating Water Transfers
Unlike irrigation systems in the U.S.A. that are sustained by farmers in a manner that facilitates urban water transfers, the majority of irrigated lands in developing countries are managed...

Water Resource Management on the Texas High Plains: Controlled Chaos or a Model of Efficiency?
Rarely is a region's social and economic well-being more closely tied to a particular resource than on the semi-arid Texas High Plains, where the water supply is variable, often limited...

Cost Recovery for Multipurpose Water Delivery Systems in Egypt
This study addresses the problem of distributing costs to the beneficiaries of incremental expenditures needed to improve the performance of the Nile water delivery system in Egypt. Emphasis...
