Abstract

It is necessary to estimate the mean velocity and thus the corresponding discharge in the ungauged mountainous streams, but the flow resistance equations available for this purpose require further testing and development for mountainous streams. Such streams are characterized by coarse bed materials, steep slopes and small water depths. For these conditions, boulders, cobbles and gravels protrude well into or completely through the flow, and the bed roughness is very large. In the present attempt, equations of Darcy - Weisbach friction factor were developed already to address this problem from which the mean velocity can be predicted. Data of different mountainous streams and laboratory flumes were used to test the equations
