Abstract

The human interventions role, particularly land use changes, is investigated in this research in Kor River hydromorphologic state (upstream of Dorudzan Dam, Fars). Within the steps of this research, there are discrete methods frameworks such as Hydrologic model using HEC-HMS, to investigate the effect of land use changes on Flood characteristics and Rosgen geomorphologic evaluation model to investigate the effect of land use changes s on environmental resources and geomorphologic changes of the river. Results of hydrologic studies by HEC-HMS indicated that in the studied time interval, the number and the value of Peak discharges are increased and the delay time and concentration time are reduced. Through simulation results for 1993-2013, this indicated that land use changes have increased the amount of flood discharge by 15% in this region and these findings are corresponds with observed floods. The results of Rosgen geomorphologic evaluation model, indicated that during studied time interval, maximum hydromorphologic changes in level 1 and 2 of Rosgen model were related to spatial ranges 1 and 2 and then ranges 4, 5 and 3 followed. In all studied spatial intervals, there are numerous transversal and longitudinal changes due to erodible boundaries and maximum changes are related to 2, 1, 3, 4 and 5 spatial intervals, respectively. The transversal changes were due to slope change, hydrologic regime, suspended and bed load, aggression to riparian lands and constructing dams.
