According to river usage and creating systems of river bed in four different sections and flow surveying in base of river according to mountainous region and coarse grain kind of it, is near to 0.0261 and Among empirical relations, we can say that HENDERSON formula is the most appropriate formula for this river and Relation presented by BRAY (1967) The amounts are more than real amount and Peter-Meyer formula are also appropriate with high accuracy and have the capabilities for being used in LORESTAN Rivers. The amount of base flow(Q) that is less, affected on river usage, so that measurements error increased.
