Sub-catchments flow losses computation using Muskingum–Cunge routing method and HEC-HMS GIS based techniques, case study of Wadi Al-Lith, Saudi Arabia

Due to permanent dry conditions in arid land basins, channels experience a great quantity of water loss during the runoff process. The objective of this study is to quantify and delineate the spatial variability of channel losses over the contributing area of the upstream side of Wadi Al-Lith, in the western region of Saudi Arabia, by using Muskingum–Cunge flow routing method. HEC-HMS model was used here to simulate rainfall-runoff relationship,...
