As the supply water for agricultural, industrial and domestic purposes has always been a basic human need, controlling floods and flowing waters through by constructing dams is an essential and fundamental issue in achieving economic self-sufficiency. In this paper, suitable locations for rubber dam installation have been studied along the Karoon River between Ahvaz and Molasani, Iran. Rubber dams are hydraulic structures that can be inflated or deflated to suit circumstances. Potential rubber dam sites have been investigated for the temporary storage of river base discharge, reducing pumping costs to agricultural lands, and for water sports and recreation. The criteria for determining the appropriate installation sites include adequate river width at the location, and suitable river breadth, height and depth upstream. Thus, all locations in the study area which fitted these criteria were selected. Five such sites, at Molasani, Seyed Saleh, Gabir, Kut Abdullah, and Daghaghele Dam, respectively, were deemed potentially appropriate for rubber dam installation.
