Multiobjective Decision Theory ? Decision Support Systems with Embedded Simulation Models
The concepts of multiobjective decision making utilizing embedded computer simulation models and dimensionless scoring functions are described in the context of a decision support system...

Stream Water Quality Modeling in Ankara Metropolitan Area
At the time this study was undertaken, untreated wastewaters from Ankara metropolitan area (capital of Turkish Republic) were being discharged directly into Ankara Creek and its tributaries....

Underground Water Conservation Districts: A Case Study in Water Resources Management
Ground water supplies approximately half of the annual water use in the state of Texas. The water law system in the state is extremely complex and non-integrated, making the management...

A Study of a Flood Control Levee Swamp System
In an attempt to reconstruct the events of the more than 100-year 1987 New Year's Eve storm that occurred on Oahu, Hawaii, an analysis of a complicated overland flow phenomenon...

Cal Poly Model Canal
The Cal Poly Model Canal (located at the Water Delivery Facility, Irrigation Training and Research Center, California Polytechnic State University, San Luis Obispo, CA) was built to accommodate...

Modelling Automatic Upstream Control with SIMCAR
The model SIMCAR solves the gradually varied unsteady flow in a branched canal network with upstream control, with particular attention given to the simulation of the AMIL radial gates....

Future Needs for Unsteady Flow Canal Models
The ASCE task committee on 'Irrigation Canal System Hydraulic Modeling' examined a number of the computer programs available for simulating unsteady open-channel...

Irrigation Delivery Design with Parameter and Objective Uncertainty
This paper investigates the effects of uncertainty in the design of hydraulic structures in an open-channel system for irrigation water delivery. Uncertainty due to ambiguity in the values...

Multicriterion Strategic Planning for Improved Irrigation Delivery Performance
An approach for assessing alternative strategies for improving an irrigation water delivery system in the context of multiple planning criteriais applied to the Alamosa River and La Jara...

Enhanced Canal System Scheduling Using a PC
The Bureau of Reclamation (the Bureau) and Lower Colorado River Authority (LCRA) are promoting water conservation through the development of computer software to enhance accounting and...

The NPUSM (Narmada) Model for Modeling Canal Flows
The NPUSM computer program was developed for the analysis of unsteady flows in canals with various types of canal structures to evaluate the Narmada Canal system in Gujarat, India. The...

Ground Water Impacts from Irrigated Ridge-Tillage
The Northern Cornbelt Sand Plain Project is a cooperative research effort between the State Agricultural Experiment Stations, USDA/Agricultural Research Service and U.S. Geological Survey...

Management, Operation and Maintenance of Irrigation and Drainage Systems (Manual No. 74)
Manual No. 74, Management, Operation and Maintenance of Irrigation and Drainage Systems, is an updated version of an earlier manual published by the American Society of Civil Engineers...

Transportation of Cities' Colorado River Water in the Salt River Project's Canal System
Cities in the Phoenix, Arizona, metropolitan area have contracted with the Central Arizona Water Conservation District to take delivery of Colorado River water. Many of their water treatment...

Impact of Nitrogen and Water Management on Ground Water Quality
Nitrate-nitrogen (NO₃-N) concentrations in shallow ground water of the Platte River Valley in Central Nebraska have been increasing since the 1950s...

Impact of Farming Systems on Water Quality in Iowa
Increased detection of nitrate and pesticides in surface and ground water has prompted concern about the impact of farming systems on water quality. A number of studies have been incorporated...

Irrigation Management to Control Sediment Pollution
Unchecked serious irrigation erosion occurs on 20% or 10+ million irrigated acres in the U.S. It may cause water use impairment from sediment pollution. Serious erosion in many areas can...

Thermal Regimes at Tailwaters of Hydroelectric Dam
Continuous temperature data were collected in the field for periods of approximately two weeks in Center Hill Tailwater. These data were analyzed to determine the warming rates and travel...

Heavy Metal Transport in the Columbia River, British Columbia
Data on the total forms of selected metals were used to assess their concentrations at two sampling sites on the Canadian Columbia River from 1984 to 1989. Cadmium, the response variable...

Overview of the Ohio Management Systems Evaluation Area
The Ohio Buried Valley Aquifer Management System Evaluation Area (Ohio MSEA) project is part of a regional study developed to investigate the effects of farming systems on productivity,...
