Estimation of Transverse Velocity and Concentration Profile Using Kumaraswamy Distribution

Abstract

Abstract To measure the lateral distribution of the velocity is very important as it is associated with riverine flow processes like distribution of shear stress, sediment concentration distribution, diffusion coefficients, secondary current’s distribution, etc. Many formulations were proposed for lateral distribution of velocity with each being somehow complex in its application. In present study Kumaraswamy’s distribution was utilized to propose a lateral velocity distribution which uses mean velocity and Kumaraswamy’s parameters a and b. It was observed in the study that skewness in the velocity distribution is a function of both a and b. Kumaraswamy’s distribution have been observed to predict the velocity profile in a satisfactory manner and when utilized to predict the transverse concentration profile along-with Ahmad’s scheme, predicted it satisfactorily.
