Experimental Investigation of the Integral Constant in Steady Flow Conditions

An elaborate experimental system was designed and built in the Hydraulics Laboratory of Civil Engineering Department of Dokuz Eylul University, in order to study the velocity distribution by means of an Ultrasonic Velocity Profiler (UVP) over rough bed at different flow rates. The UVP which has the advantage of providing instantaneous velocity distribution was also used to measure the bed elevations. The shear velocity, u* and the integral constant, Br were calculated from the mean velocity profiles by applying the Clauser Method and compared with those given in the relevant literature.
