Transferring Conserved Water
The proposal to transfer water salvaged by water conservation programs from one area to another is a new concept. Imperial Irrigation District (District), located in the southeast portion...
Reusing Treated Wastewater for Irrigation of Raw-Eaten Vegetable Crops in Monterey County, California
The demonstration project was entitled the Monterey Wastewater Reclamation Study for Agriculture (MWRSA). It was principally a field trial study of the feasibility of irrigating food crops...
Simplified Prediction of Storm Surge on an Open Coast Using a Microcomputer
Computer-generated wind fields have a flexibility that is not available with standard manual procedure; i. e. different illustrative concepts can be given a trial run at low cost. A spreadsheet...
On-Site Microcomputer Control of a Combined Sewer Overflow Diversion Structure
This paper describes the design of an inexpensive system for controlling combined sewer overflows using on-site equipment (raingauges, flow gauges, automatic gates, and microcomputers)....
Water Erosion from Irrigation?An Overview
Erosion and sedimentation by water includes the process of detachment, movement, and deposition of soil particles (14). Under irrigated conditions, the erosive process is water flowing...
Effects of Erosion on Soil Productivity
Erosion-caused crop production decreases up to 50% have been measured with decreases of 15 to 30% commonly reported. Furrow erosion on irrigated land redistributes topsoil, decreasing...
Erosion and Sedimentation Processes in Irrigation
Soil erosion occurs when fluid in motion detaches and transports soil particles. Sedimentation occurs when the fluid transport capacity decreases. Both the hydraulic forces of moving water...
Sediment and Erosion Control Implementation: An Overview
The responsibilities of the federal, state and local governments in sediment and erosion control are reviewed. The effectiveness of cost-shared and non-cost-shared technical assistance...
New Developments in HEC Programs for Flood Control
Since the Hydrologic Engineering Center (HEC) started in 1964, the evolution has been toward packaged programs that perform a variety of computation options. Two examples are the flood...
Water Infrastructure: Research and Education Needs
Problems with infrastructure have received considerable attention but not much has been written about implications for research and education. Education and research should be aimed at...
Irrigation in Mexico
Mexico has a great historic tradition in the construction of works for irrigation; irrigated agriculture has been practiced since the pre-hispanic epoch. The development of hydro-agriculture...
Irrigation Development in Alberta, Canada
Agricultural production in the southwestern part of the Canadian prairie provinces is limited by insufficient rainfall for optimum crop production. To overcome this moisture deficiency...
Traveling Trickler Center Pivot Design
There have been a number of proposals to improve the center pivot irrigation system in order to overcome the inherent inefficiency from high evaporation losses and energy requirements....
Strategy for Ground Water Planning
Though the percentage of ground water development is only 40%, many areas of India are over developed, where water tables are falling rapidly, due to over pumping. In some areas the surface...
Hansen Dam Sediment Modeling Study Impact of Water Supply vs. Flood Control Operational Modes on Sediment Deposition in the Reservoir Area
