Irrigation management systems of Dong Irrigation District based on GIS, MDS and AMS

Abstract

All of geographical information system (GIS), management decision-making system (MDS) and automatic monitoring system (AMS) are important signs of the modernization of irrigation management. Although these technologies have been applied in some irrigation districts, their functions have not been generally integrated systematically. The authors, taking Dong Irrigation District as an example, developed an integrated irrigation management system including GIS, MDS and AMS. This study focused on the integration of all functions of GIS, MDS and AMS, such as management of basic spatial datum, prediction of water requirement of crops, decision-making of water supply, monitoring of irrigation pump stations and canal system, evaluations of management system, etc. In particular, evaluations of management system can provide important feedback information for improving irrigation management decision-making.
