The objective of the present study is to assess the variation of Manning's roughness coefficient on flow characteristics of Nethravathi River. The channel roughness plays an important role since it is not a constant parameter and varies along the length of the river. Article: Effect of roughness coefficient on discharge and flow depth by using hydraulic model for Nethravathi River Basin, India Journal: International Journal of Hydrology Science and Technology (IJHST) 2021 Vol.11 No.1 pp.114 - 124 Abstract: The river stage and discharge are dynamic due to various factors affecting the flow characteristics in a natural channel.
