Simulation Model for Economic Irrigation Project Planning and Design
The principle design parameters considered are: water supply configurations (quantity, source and storage); shapes and sizes of the area to be served; on-farm irrigation techniques; cropping...
IRSIS, A Software Package for Irrigation Scheduling
IRSIS (IRrigation Scheduling Information System) has been developed to solve problems concerning irrigation scheduling at field level. For a given climate, crop and field it offers the...
Hydrologic and Institutional Water Availability
A simulation study was performed to evaluate the amount of water which can be supplied by a system of 12 reservoirs located in the Brazos River Basin. The generalized computer models HEC-3...
Water Quality Management During Low-Flow Periods: A Systems Analysis Approach
Water quality objectives may require water managers to consider deviations from original project purposes to provide downstream water quality maintenance during low-flow periods. The decision...
The Los Vaqueros Model: A Microcomputer-Based Reservoir Planning System
This paper describes the development and application of a set of microcomputer models for the evaluation of a complex water resources project. The Los Vaqueros Model includes components...
Storms and the Occurrence of a Turbidity Interface/Maxima in a Fresh Water Estuary
A combination of Landsat, field data and modeling analyses reveals a turbidity interface/maxima in the lower reaches of a freshwater tributary or 'estuary.' Mode...
Highway Erosion Remedial Measures
Soil erosion from highway ditches, cut slopes and fill slopes present a continuous problem to roadway designers, geotechnical engineers, and construction and maintenance personnel from...
100 Years of Sedimentation Study by the USGS
On January 15, 1889, the U.S. Geological Survey began collecting sediment data on the Rio Grande at Embudo, New Mexico. During the past 100 years the U.S. Geological Survey's...
History of the Federal Interagency Sedimentation Project
Since 1939, the date of the Project's inception, the team has operated under the direction of two lead agencies - the U.S. Geological Survey and U.S. Army Corps of Engineers....
Applications and Research in Sediment Delivery and Routing Models in the USDA-Forest Service
Sediment delivery and routing are important watershed management issues in the USDA-Forest Service. The relationship between forest management activities and stream morphology, resident...
Lessons from Ten Years Experience in 2D Sediment Modeling
