This research evaluates the performance of the Dagharah-Huriyh irrigation project in Iraq and proposes managerial methods to enhance its operation. The study area is located in the Qadisiyah (formerly Diwaniyah) Governorate, along the Dahghara stream. The Dholmiya Canal, Hilla-Diwaniyah Irrigation Project, Diwaniyah-Shaafeyah Irrigation Project, and desert stretch along its north, west, and east borders. Fieldwork involved measuring water inflow, soil moisture content, and root zone depth. Nine fields were selected for the project, and their water application efficiency ranged from 37.33% to 67.12%. The average efficiency is approximately 56.45%, and the median efficiency is 57.9%. Field B2 and field C3 had low water application efficiencies of 37.33% and 46.45%, respectively. This indicates that farmers overirrigated or mismanaged water in these areas, causing crops to lose a lot of water. Storage efficiency varied between 31.68% and 98%, while distribution efficiency exceeded 90% for all fields. Infrastructure upgrades, water management optimisation, and modern equipment and technologies are needed. These adjustments aim to reduce water losses, improve water use, and promote sustainable agriculture in the Dagharah-Huriyh irrigation project. [ABSTRACT FROM AUTHOR] |
