History of the USDA-ARS Experimental Watersheds on the Washita River, Oklahoma
A national experimental watershed network, operated by the Agricultural Research Service of the US Department of Agriculture, was established in 1959 to conduct research on the effects...

The ASCE Standardized Reference Evapotranspiration Equation
Prepared by the Task Committee on Standardization of Reference Evapotranspiration of the Environmental and Water Resources Institute of ASCE. This...

Irrigation Hydrology: Crossing Scales
Hydrology is the science concerned with distribution, circulation, and properties of water of the earth and its atmosphere, across the full range of time and space scales. Subject matter...

A Paradigm Shift in Irrigation Management
In coming decades, irrigated agriculture will be called upon to produce up to two thirds of the increased food supply needed by an expanding world population. But the increasing dependence...

Water Quality Aspects of Irrigation and Drainage: Past History and Future Challenges for Civil Engineers
This paper presents a brief history of irrigation and drainage related to ASCE activities on its Jubilee. This paper discussed legislation and policies that affect irrigation and drainage...

Two constructed wetlands demonstration projects in the Imperial Valley of California are being designed to help improve the water quality of the New River, which originates in Mexico and...

Introduction
This chapter serves an introduction for the book. The purpose of the manual is to present to users a process of selecting an irrigation method and to inform them of the capabilities and...

Irrigation Method Selection Process
Intelligent selection of the irrigation method that best meets the goals and objectives of an irrigated agricultural development is of primary importance in the design process. A system...

Surface Irrigation
Surface irrigation refers to a large group of irrigation methods in which water is distributed by gravity over the surface of the field. Water is typically introduced at the high point...

Drip/Micro Irrigation
Drip/micro irrigation (also previously referred to as trickle irrigation) refers to a variety of irrigation methods in which water is delivered directly to small areas adjacent to individual...

Sprinkler Irrigation
In sprinkler irrigation, water is applied to the soil using a pressurized piping system with nozzles, jets, or perforated pipe that sprays the water into the air. These sprinkler devices...

Subirrigation: Water Table Management
Water table management (subirrigation) is accomplished by controlling the water table, usually through a subsurface drainage system. The crop is subirrigated with water being furnished...

Fouling of Nanofiltration Membranes due to Calcium Sulfate Precipitation in Treatment of Agricultural Drainage Water

Economic Valuation of Agricultural Water Use for Large-Scale Modeling
(No paper) A state-wide irrigated agricultural production model has been developed for California. The model is an extension of the Central Valley Production (CVP) Model that was most...
