Productivity and Efficiency
According to the U.S. Environmental Protection Agency, water efficiency is the smart use of our water resources through water-saving technologies and simple steps. Using water efficiently will help ensure reliable water supplies today and for future generations. Topics addressed in this theme provide insights, lessons, and guidance on how diverse stakeholders are working to improve water management and reduce water use.

Sediment Routing in Irrigational Canal Systems
Published:
January 1, 1973U.S. Agency for International Development, Colorado State University
The routing of bed material load through a branching irrigation canal system in such a way as to insure sediment discharge equilibrium is considered. All the sediment entering the system is disposed of with the water. It is shown that the system equilibrium can be more easily achieved if smaller...Read more
Steady and Unsteady Flow of Fresh Water in Saline Aquifers
Published:
June 1, 1972U.S. Agency for International Development, Colorado State University
Problems of flow involving fresh water overlying saline water in aquifers and methods for their analysis are reviewed. Equations amenable to mathematical solution generally involve the idealization of treating the fresh water as a distinct zone separated from the underlying saline water by a sharp...Read more
Planning Sediment Distribution in Surface Irrigation Systems
Published:
November 1, 1971U.S. Agency for International Development, Colorado State University
This report deals with planning sediment load distribution in surface irrigation systems. The object is to route water and sediment through an irrigation canal network so that sediment discharge equilibrium is achieved by diverting the sediment inflow with the farm supplies. A computer simulated...Read more
Maximum Water Delivery in Irrigation
Published:
August 1, 1971U.S. Agency for International Development, Colorado State University
In order to increase the water delivery efficiency of an existing irrigation system, it is proposed that modern mathematical optimization techniques be applied to the management of irrigation water delivery. A deterministic mathematical model is developed to simulate the events that occur in...Read more
Check - Drop - Energy Dissipator Structures in Irrigation Systems
Published:
May 1, 1971U.S. Agency for International Development, Colorado State University
There is a large volume of available literature regarding small energy dissipator structures. Existing publications present basic information for particular types of structures. This information has been compiled in order to present present-day available design information. Also, research topics...Read more
