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.

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
Hydraulics of Trickle Irrigation Emitterlines
Published:
January 1, 1973U.S. Agency for International Development
A study was conducted to investigate the flushing flow characteristics of flushing emitters, the hydraulics of emitter lines under steady flow conditions, and the uniformity of distribution of emitters as influenced by emitter variations and other environmental factors. The study was composed of...Read more
Land and Water Use Potentials: Tungabhadra Irrigation Project, Mysore, India
Published:
October 1, 1972U.S. Agency for International Development
The study investigated land and water use potentials of the Tungabhadra Irrigation Project (TBP) located in one of the most sparsely settled and impoverished areas of Mysore State, India. Its objectives were to determine the most profitable crops that could be grown on the black soils in the TBP...Read more

Costa Rica, Latin America and the CaribbeanNeeds and Requirements for Irrigation, Comayagua and Vicinity, Honduras
Published:
June 1, 1972U.S. Agency for International Development
The valley areas in the vicinity of Comayagua and Siuatepeque offer considerable potential for agricultural development. Irrigation facilities have been constructed capable of delivering irrigation water to areas for more extensive than those currently irrigated. An analysis is made of the adequacy...Read more

Guatemala, Latin America and the CaribbeanDevelopment of Tubewell Irrigation in Bangladesh: An Analysis of Alternatives
Published:
February 1, 1972U.S. Agency for International Development
Facilities for irrigation would permit substantial increases of agricultural production in Bangladesh. Only with irrigation as a boro crop in the six-month dry season possible. With its continual sunshine and the absence of recurring floods and storms that damage crops in other seasons, this period...Read more

South East AsiaEstimation of Irrigation Requirement for Venezuela
Published:
January 1, 1972U.S. Agency for International Development
Christiansen's formula was used to compute evaporation and potential evapotranspiration using 1013 months of data from 19 stations in Venezuela. Thirteen probability levels of precipitation were determined for each station. Potential irrigation requirements for 16 stations were computed based...Read more

Latin America and the CaribbeanPlanning 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
