Using modelling to improve operational performance in the Cu Chi irrigation system, Vietnam

Abstract

The Cu Chi irrigation system in Vietnam forms part of the Dau Tieng reservoir system in the Dong Nai basin. Water competition in this system is intensifying as a result of increasing urban and environmental demand. System operation modelling using the Irrigation Main System OPeration (IMSOP) model was applied to the Cu Chi irrigation system, Vietnam, to improve its operational performance. The operation improvement process involved the comparison of supply and demand during two years, 2001 and 2002, revealing that the system's operation was carried out without consideration of the crop water demand and proper canal regulation. The retrospective operational analysis revealed a substantial amo..
