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...

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...

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...

Watershed Management Education at The University of Arizona
Watershed management education at the University of Arizona is described and discussed in the perspective of other educational programs, and national and international activity. The Watershed...

Predicting Droughts for the South Platte River System
In this paper we apply probability theory and stochastic processes to determine drought properties, particularly drought duration. Spccilicslly, we model the sequences of wet and dry years...

Desert Wetlands
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...

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...

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...

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...

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...

Use of Economic Optimization to Evaluate New Facilities
(No paper) The confluence of the Sacramento and San Joaquin rivers and the San Francisco Bay forms the largest estuary on the West Coast. Known as the Bay-Delta, the region supplies drinking...

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...

Water Resources Engineering '98
This proceedings, Water Resources Engineering 98, contains summaries of papers presented at the 1998 International Water Resources Engineering...

Inviting Trouble Downstream
When dam-building advocates, representing power generation, irrigation and flood control interests, get their project built, flood control ranks third in priority. Soon, development encroaches...

Interest in Deposits (available only in Geoenvironmental Special Issue)
Sediment accumulating in reservoirs worldwide is gradually reducing storage capacity, posing a long-term threat to supplies of drinking and irrigation water. The buildups also highlight...
