Abstract

The base flow of permanent rivers which emanate from the mountainous regions of Iran is provided from the snowmelt runoff during the dry seasons. In precipitation-runoff studies, two phenomena occur in high elevations. With the height increase, the temperature is reduced and this results in the precipitation to change from rain to snow beyond the threshold temperature. Moreover, with the logic pyramid mountains resumption the surface to save the snow is reduced in higher positions.This paper studies the elevation change effect on snowmelt runoff in KARUN RIVER BASIN. Satellite snow covered maps in the region during study period were collected. The region was divided into five zones by the GIS. Moreover, snowmelt runoff model (SRM) was calibrated and validated using climatic variables of two periods containing one wet year (1991-92) and one dry year (1992-1993). The results showed that SRM efficiently predicted the total daily runoff of snowy regions without the need for ground data and just relying on the remotely sensed snow covered areas. In the next step, contribution of snowmelt runoff was simulated by inserting the snow covered areas during the study period and artificially eliminating rain form of precipitation.It was further found that the role of snowmelt in runoff is bolder in higher elevations in the study region. Using model results, the specific discharge caused by snowmelt during the wet and dry periods was determined to be 0.70 (mÙ3/kmÙ2) and 0.23, respectively. The snowmelt runoff volume for the wet and dry years was estimated to be 13833.9 and 5492.5 million cubic meters respectively.
