Abstract

Examination of effects of Rangeland management practices is one of the main subjects for future planning of natural resources management and restoration projects. In terms of, there are no tools for the assessment and record changes in flood conditions, erosion and sediment watershed basins using hydrologic model for simulation catchment behavior before and after range Management practices is as a useful tool achivement toward this purpose. According to this research was done purpose of the purpose of this study was evaluation of land cover changes and on runoff in Gelerood basin in Borujerd county-Lorestan Province using HEC-HMS Hydrologic model was optimized and calibrated. Then, to determination of rangeland condition changes on concentration time that will cause a delay in the transfer of water after practice calculated and during frequent field visits improvement of vegetation of basin and promotion of hydrologic model calculated by SCS method and By applying changes in input model attempted to simulate flood behavior for existing events. Criteria's such as runoff piek and amount of flow determined for evaluation and measured in two situations of before and after land use. Results show that this model (HEC-HMS) is suitable for predicting and simulating of runoff in basin according to acceptable accuracy. Because of decreasing of Curve Number cause of plant cover increasing, the best scenarios to decreasing runoff are EXCLUSION, available management of rangelands, CONFLAGRATION and HEAVY GRAZING respectively. Therefore to decreas runoff must increase plant cover by any management tools even EXCLUSION which it is the last way for prevention of natural hazardous and land degradation, orchards, built places beside of river and beside of Borujerd city.
