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

Latin America and the CaribbeanDesert Strip Farming, a Modified Dry Farming Method Using Rainfall Multiplication
Published:
July 1, 1970U.S. Agency for International Development
Reviews progress to date on a runoff distribution strategy in which rain water is harvested in collectors and then channeled to nearby crop areas. The report explains that an inexpensive short-distance irrigation method is badly needed in sunny, potentially arable regions where the limited rainfall...Read more
Irrigation Requirements from Evaporation and Climatic Data
Published:
January 1, 1970U.S. Agency for International Development
Evapotranspiration data are available from lysimeters, field plot sampling and other methods for a variety of crops at various locations. At a given location there is frequently considerable spread or scatter in the data. This paper presents formulas and methodology for estimating evaporation...Read more
