Abstract :
Earth dams have been used widely recently in flood and sedimentation control projects and feeding ground waters in country's watersheds and correct locating for such structures is necessary for increasing their efficiency. In this work, it is attempted to determine the correct locations for constricting earth dams in Yoosef-abad watershed in Tabas using v and incorporating information layers. Thus maps for local limitation (boundary out of 10m to river), natural local factors (slope percentage, boundary to river, geomorphologic units and geological features), economical factors (Resource materials, boundary to road, boundary to aqueduct and boundary to residential area) were entered into GIS environment and heterogeneous local layers were incorporated and made homogenous and all took phase values between 0 and 1. Due to heterogeneity of layers' values, layers were weighed. Finally, layers were incorporated and combined index map was obtained, where optimal locations for constructing earth dam were given priority, and the best location for construction in the area was determined. Comparing results with field studies showed that the selected locations are acceptable in terms of engineering and meeting needs of residents, and proposed method can be generalized to other watersheds.
