Managing the Excess Floodwaters in the Lake Hemrin Using Remote Sensing and GIS Techniques

Lake Hemrin is located in the middle east of Iraq, about 50 km from Iraqi-Iranian border. The lake main fish source and provides water for nearby farms. However, due to various socio-economic environmental management issues, system a difficult resources challenge. Moreover, receives floodwaters annually over its storage capacity; therefore, there risk flooding areas downstream lake. To this end, research developed optimization solutions design flood escape paths area using Analytic Hierarchy Process (AHP) Genetic Algorithm (GA). Among three initial proposals, i.e., Adhaim River, Wadi Naft, Salahdin, models optimized each proposals suggested that Naft would require only 3.88 km3 cut fill volume compared River 34.33 km3. latter serve more people agricultural lands. GA AHP techniques optimize have shown these can discover shorter pathways requiring less costs while retaining other features. proposed optimal path substantially influence construction flood-prevention strategies area.
