Abstract

In order to determine the effect of bed roughness on velocity distribution, the AA. used 7 different configurations of bed roughness, with 16 test runs of varying discharge and slope for each configuration. Results indicate that velocity profile shape remains fairly constant for a given slope and roughness configuration as discharge increases. As slope increases, the profiles become less linear. Rates of velocity increase suggest that roughness elements spaced at a length/height ratio of about 9 are most effective at creating flow resistance over a range of discharges in channels with steeper slopes
