Development and Implementation of the Wekiva River Basin Regulatory Program in Central Florida
The St. Johns River Water Management District developed a comprehensive surface water management program for the basin. Between 1987 and 1989 the District implemented basin specific design...
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...
Effect of Water Depth and Groundwater Table on Infiltration from Recharge Basins
The actual effect of water depth on infiltration depends on the depth to groundwater and on whether the wetted perimeter of the basin is clean or covered by a clogging layer of fine particles...
Economic factors of Drainage Water Reduction
Properly designed and maintained pressurized systems provide better irrigation control and greater infiltration uniformity. But irrigation costs are increased. Imposition of drainage water...
Treatment, Reuse and Disposal of Drain Waters
Treatment, reuse and disposal options of agricultural drainage water present formidable technical problems. Various treatment technologies and disposal methods have been studied. Reuse...

Comparison of Design Rainfall Criteria for the Southwest
The design of drainage and flood control facilities or the management of floodplains for alluvial fans is extremely sensitive to the design rainfall criteria that is used as input to the...
Inclusion of Wetlands in Designated Floodway Studies
The purpose of this paper is to propose a change in the traditional methods and procedures used by hydrologist and hydraulic engineers to define floodways and floodway fringe areas. We...
The Bearing Capacity of Debris Flows
Debris flows are made of a cohesive muddy matrix in which large and heavy particles exist in suspension. To explain how these particles are maintained in suspension, several mechanisms...
Feasibility of Stormwater for Recharge in the Las Vegas Valley
Rapid growth in the Las Vegas Valley has increased the pressure on the limited water supply. The increased water demand has stimulated public interest in water conservation and the potential...
