Management of Groundwater Overdraft in the Phoenix, Arizona, Area
By law, the overdrafting of groundwater in the Phoenix, Arizona, area must cease by the year 2025. Safe yield can be achieved by means of conservation, water supply augmentation, and condemnation...
Supplemental Irrigation by Runoff Farming: An Economic Assessment
A simulation model was used to evaluate the economic potential for using runoff farming techniques for growing grain sorghum at two locations in Texas. The results show that the yearly...
Sprinkler System Design for Frost Protection
Both undertree and overtree systems for frost protection by sprinkling are currently being used. The criteria based on experimental results and theoretical modeling have been reviewed...
A Modern Approach to the Design of Grassed Channels
The design of grassed channels can be based on modern fluid mechanics principles. The resistance to flow in a grassed channel is linked directly to the relative roughness of the flow through...
The Colorado River Salinity Program?An Overall Perspective
Economic losses resulting from increases in salinity in the Colorado River system were estimated to be $311 million annually in 1986. As a result of protests by Mexico to the United States...
Strategies to Reduce Salt Load in Drainage Water
A study of irrigation efficiency, drainage flow and trace element loading in the drainage water from a 14000 ha irrigation district on the west side of the San Joaquin Valley of California...
Reduction of Deep Percolation and Drain Water
Management of irrigated agriculture for control of toxic trace elements in agricultural drainage waters must include consideration of a variety of factors and their interactions with one...
