Knowledge of flow resistance for different flow conditions helps for better understanding of water resources problems, such as flood routing, channel enhancement, backwater curve computation, and scouring.In studies of flow with suspended sediment two issues often raised are the effect of suspended sediment on velocity distribution and flow resistance. The material going into suspension changes the flow and fluid characteristics and, as such, influence on the resistance to flow. So it is needed to check the effect of suspended sediments on flow depth for exact design of channel. Accurate flow resistance values may improve the channel design and help in deciding depths of the channels. At the end of this book, a list of references has been given that would helps the readers for further reading.Final results are presented in this book and recommendations were drawn for researchers and planners. The authors appreciate the efforts of Barthlemy Chaton and his team in facilitating and highly acknowledge publishing of it by VDM Publishing House Ltd., for technical knowledge sharing internationally.
