Derivation of Equation for Mean Suspended Sediment Based on Probabilistic Concept

Abstract—An accurate estimation of sediment discharge in rivers and streams should be solved for the appropriate river management and monitoring. In this study, a new formula which has minimum parameters considering existing ones with a concept of entropy by a probabilistic approach, was developed and mean suspended sediment concentration were estimated. Results of this new formula were verified with the experimental results which were conducted with a steady state and gradually injecting sediment (D= 105 ㎛) in a rectangular cross-sectional flume previously. The relationship between the measured sediment distribution and the estimated sediment distribution has a good agreement.

Index Terms—Entropy, entropy suspended sediment parameter, mean suspended sediment concentration, Probabilistic approach.
