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...
Urban and Agricultural Competition for Water, and Water Reuse
Competition for water can be resolved by construction of more facilities for storing water (dams, groundwater recharge) in wet years for use in dry years, by weather modification, watershed...
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...
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...
Computerized Irrigation Project Earthwork Design
A procedure was developed to perform earthwork optimization and land-leveling design for irrigation projects using aerial photogrammetry, a microcomputer and civil engineering computer...
Optimal Contaminant Plume Management with US/WELLS
A micro-computer based software package developed at Utah State University for computing optimal pumping strategies for well systems (US/WELLS) is demonstrated. US/WELLS is used to determine...
Optimizing Conjunctive Water Use in a Dynamic Stream-Aquifer System with US/REMAX
Long-term water management planning models frequently use large time steps and must employ fairly crude assumptions (such as average climatic conditions, etc.). Managing stream aquifer...
Nitrogen and Phosphate in Vadose Waters in Heber Valley
During the last decade best management practices have been gradually implemented in Heber Valley to maintain and enhance the qualities of surface waters that flow into Deer Creek Reservoir....
Computer Modeling Approach to Optimize Pumping for Containment of LNAPL Contamination in Unconfined Aquifers
This paper presents an approach to optimize pumping for immobilizing a floating contaminant consisting of a light non-aqueous phase liquid in an unconfined aquifer. The approach combines...
Ground Water Management in the Salt Lake Valley, Salt Lake County, Utah
The perfected and approved water right applications in Salt Lake Valley could potentially withdraw from the principal aquifer a quantity of water far greater than the annual recharge....
Ground Water Management for Wellhead Protection in a Confined to Semiconfined Aquifer, Salt Lake County, Utah
The 1986 Amendments to the Safe Drinking Water Act (SDWA) established the first nation-wide program to protect ground water resources used for public water supplies. The SDWA seeks to...
A Framework for Integrating NPS Pollution Prevention and Optimal Perennial Groundwater Yield Planning
Water management agencies are responsible for protecting and guaranteeing the sustained availability of groundwater of adequate quality. The presented procedure helps determine water Best...
Point Precipitation Models to Simulate Water Balance at a Constructed Wetland
We compare two point precipitation models in a water balance simulation performed at a wetland constructed to treat municipal wastewater. The first precipitation model uses a simple Poisson...
Probabilistic Characteristics of Elapsed Time Between Rainfalls
The elapsed time between rainfalls is analyzed statistically using the hourly rain data at two locations: the flat-plain at Urbana, Illinois and the northwestern Appalachian foothills...
Climate Change: Is Trouble Ahead for Water Engineers?
Very long range forecasts of future global warming from 2 to 5?C have been made as a result of the increase in carbon dioxide and trace gases in the atmosphere due to man's activities....
The Integration and Management of Ground- and Surface-Water Resources for Drought Response in New Castle County, Delaware
This paper reports on a program for the integration and management of ground- and surface-water resources for drought management purposes in the southeastern area of the Commonwealth of...
Controlled Versus Conventional Drainage Effects on Water Quality
Fertilized cropland is a nonpoint source of nitrogen and phosphorus which can contribute to nutrient enrichment problems prevalent in many surface water ecosystems. Research has shown...
Effect of Agricultural Drainage on Water Quality in the Mid-Atlantic States
Agricultural drainage development in the form of drainage alone and controlled drainage-subirrigation (CD-SI) has created conflicts with environmental concerns. Most concerns the lack...
