The rapid expansion of microcomputer technology provides a tool which can improve irrigation management practices. Commercially available software packages such as database management systems (DBMS), spreadsheets, mapping systems, and programming languages can greatly improve data storage, retrieval, analysis and reporting. From the authors' experience in India, computer-assisted irrigation management can also be developed using this technology. It provides an organized and comprehensive set of tools to improve information flows and assist irrigation managers in making timely and effective management decisions.

This paper investigates the effects of uncertainty in the design of hydraulic structures in an open-channel system for irrigation water delivery. Uncertainty due to ambiguity in the values of physical parameters and due to vagueness in the specification of system performance objectives (adequacy, efficiency, dependability and equity) is modeled. Two design objectives, maximum performance and minimum cost, are considered in a simple illustrative example. Implications for design and analysis of large-scale delivery networks in an uncertain environment are discussed.

Outlines IWMI's external and other comparative performance indicators that allow for analysis of irrigation performance across systems. The purpose of these indicators is to understand the current situation with respect to productive utilization of land and water, to compare relative performance of systems, and to identify where performance can be improved.

Changes in the way water is used in one part of a river basin often affect how water is used somewhere else in that basin. This report introduces the concept of hydronomic ( hydro water + nomus management) zones that were developed to help untangle some of the complexities of basin-wide water resource use.
