Agriculture
Globally, the agricultural sector consumes about 70% of the planet’s accessible freshwater. Because water is vital for the success of agriculture, proper water management techniques are necessary to meet food and fiber material demands around the world. Resources available here pay special attention to efficient irrigation and sustainable agriculture techniques.

Procedure for Evaluating the Cost of Lifting Water for Irrigation in Egypt
Published:
August 1, 1984U.S. Agency for International Development, Colorado State University
An analytical model for assessing alternative water lifting systems in Egypt, designed for use by policymakers, is presented. The procedure computes the cost of lifting water from tertiary delivery canals to farmers' fields on the basis of a combination of 23 variables: economic factors,...Read more

Egypt, Arab Rep., Middle East and North AfricaRelation Between Irrigation Water Management and High Water Tables in Egypt
Published:
July 1, 1984U.S. Agency for International Development, Colorado State University
High water table levels presenting hazards to crop growth were measured at field sites in upper, middle, and lower Egypt. Water table contribution to evapotranspiration was significant at each site. A water balance model of the water table aquifer was used to predict the effect of various...Read more

Egypt, Arab Rep., Middle East and North AfricaConsiderations of Various. Soil Properties for the Irrigation Management of Vertisols
Published:
May 1, 1984U.S. Agency for International Development, Colorado State University
Most of the irrigated soils of the Nile River Delta are classified by the U.S. Soil Taxonomy as vertisols. For proper irrigation management, the extensive cracking exhibited by these soils upon drying requires an understanding of how crack formations affect, among other factors, infiltration,...Read more

Egypt, Arab Rep., Middle East and North AfricaA Technical and Economic Analysis of Low Lift Irrigation Pumping in Egypt
Published:
May 1, 1984U.S. Agency for International Development, Colorado State University
The need for small, efficient, low-lift pumping devices is being recognized worldwide. Many developing countries need such pumps to lift irrigation surface water 0.5 to 3 meters. This paper analyzes the technical and economic characteristics of low-lift pumps. Water wheels and both portable and...Read more

Pakistan, South East AsiaHydraulic Design of a Canal System for Gravity Irrigation
Published:
April 1, 1984U.S. Agency for International Development, Colorado State University
Irrigation by gravity from a water delivery system where the difference in elevation between the canal's source and the fields is small requires careful use of the limited head available. Drop structures normally used to control flow are not used in order to conserve head. Instead, a desired...Read more
