Improvement of hydraulic characteristics for Dujila canal

The availability of water for rural households’ residential usage and for agricultural has been made possible through irrigation programs. In the Dujila irrigation project, concrete is being used to line irrigation canals in order to save water and expand the irrigated area Using the Hydrologic Engineering Center River Analysis System (HEC-RAS). It was shown that canal seepage contributes significantly to groundwater recharge. According to estimates, the annual groundwater recharge in the irrigated areas will be reduced by about 50% following concrete lining. This helps to preserve a significant amount of water that can be utilized to expand the irrigation area and provide irrigation water to more people. According to estimates, the annual groundwater recharge in the irrigated areas will be reduced by about 50% following concrete lining. This helps to preserve a significant amount of water that can be utilized to expand the irrigation area and provide irrigation water to more people Lining decreases seepage, which allows for significant water savings that can be put toward expanding the irrigation area. The findings demonstrated that, in addition to raising the water level, concrete lining outperformed stone cladding in terms of increasing water velocity and lowering cross section area.
