Efficient Water Use in Irrigated Wheat
Border irrigated wheat is the main crop in arid, semiarid and winter-dry areas in Mexico. In general water use efficiency is low, since border irrigation systems are not well designed...
Description and Evaluation of Program CANAL
CANAL was developed in 1987 at Utah State University to perform hydrodynamic computer simulations of canal networks. This paper describes the model and offers opinions on the model's...
Description and Evaluation of Program: SNUSM
The Staggered Net Unsteady State Model (SNUSM) was developed in the early 1980's by the United States Bureau of Reclamation under the direction of Bob Gooch and Al Graves....
Description and Evaluation of Program MODIS
MODIS is an implicit hydrodynamic modeling package that has been developed to investigate the hydraulic performance of dynamic controlled irrigation systems. The model's most...
Description and Evaluation of Program: DUFLOW
DUFLOW is a micro-computer software package for simulating one-dimensional unsteady flow in open channel systems. It is designed for simple networks of channels with simple structures....
Description and Evaluation of Program: USM
USM was developed by the USBR for simulating unsteady flow conditions in canals with either manual or automatic gate operation. This paper describes the model and discusses the relative...
Description and Evaluation of Program: CARIMA
The CARIMA code simulates unsteady free-surface flow in simple or multiply connected systems of rivers or canals. The simulation uses the Preissmann implicit finite-difference method for...
Surface Water/Groundwater Interaction Studies
Studies were performed on a high elevation (2440 meters or 8000 feet) valley stream system and a high (1980 meters or 6500 feet) cold desert stream system in Wyoming, to analyze the surface...
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...
The Ala Wai Canal?From Wetlands to World-Famous Waikiki
The Ala Wai Canal, a man-made tidal estuary on the island of Oahu, Hawaii, is located about a half mile (0.8 km) landward of Waikiki beach and is two miles (3.2 km) long. As Hawaii's...
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....
Field Application of Transient and Steady-State Canal Models in Thailand
A transient (unsteady) flow model for simulating the hydraulics in irrigation canal networks was developed and tested in Thailand. A steady-state hydraulic model was subsequently developed...
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...
Effects of Uranium Mining, Puerco River, New Mexico
Effluent from uranium-mine dewatering and acidic water released by a tailings-pond dike failure increased radionuclide activities in streamflow in the Puerco River in New Mexico and Arizona....
Geochemical Mass-Balance in a Small Forested Watershed in Southwestern Pennsylvania
An intensive hydrologic investigation of the North Fork Bens Creek Watershed on Laurel Hill in southwestern Pennsylvania was made during 1984-85. Precipitation was sampled weekly, and...
Use of Stable Isotopes, Tritium, Soluble Salts, and Redox-Sensitive Elements to Distinguish Ground Water from Irrigation Water in the Salton Sea Basin
Evaporative concentration of irrigation water diverted from the Colorado River to the Salton Sea basin for several decades has produced an overlying system (that includes drainwater and...
