Hydraulic Characteristics of Mountain River

River studies are multidisciplinary but the two most prominent areas are hydrology and hydraulics. Hydrology treats the occurrence distribution movement and properties of the waters of the earth and their relationship with the environment within each phase of the water cycle. The term hydraulic characteristics of rivers refer to the processes of water and sediment movement in a natural channel and the physical factors related to them. Such parameters include flow depth and type flow velocity wetted perimeter water surface width channel roughness and slope channel alignment and catchment area. This study focuses on some aspects on the hydraulic characteristics of Rangpo River. The River is a right bank tributary to the Tista River. The stream joins the Tista at Rangpo town East Sikkim. This study examines the various types of hydraulic features like flow pattern velocity of water hydraulic drop water velocity thalweg water pH etc. are measured.
