چکیده

Garesoo river basin in Doab-Merek, as studying area of this research, located in northwest of Kermanshah province in west part of Iran. There is long-term hydro climatologic data in this basin about rainfall, temperature, etc. (more than 50 years) and main river data (about 35 years). Due to intense fall down groundwater level and seasonal river drying, in the past 10 years .It was necessary that studies be done to the management water resources of region. Studies performed at first by linking MODFLOW to WEAP model with information and initial understanding of the geology and the others information of the area. The results were not satisfactory especially regarding the prediction runoff basin in outlet, despite the long term data. After these initial studies, and based on complete studying, it was cleared that complicated geological conditions with new Tectonics activities were key to the adaptation of the model to reality. In addition, geophysical surveys using radar approach showed that the fault is in match with the trend of river, and it can recharge river in wet season from hard rock water resources. Finally we achieved a good acceptance matching between calculated and observed discharge of river in Doab-Merek station with satisfactory results.
