Description :
Stream frequency, drainage density, drainage texture and other parameters in the Ladhiya and Lohawati River Basins show a strong structural/tectonic control over the drainage of the Tanakpur-Champawat area. Field studies reveal that several parts of the study area are structurally controlled and neotectonically active. Such neotectonic activities are especially associated with the configuration and evolution of the present day topography. Ample evidence of active tectonics such as landslides, river terraces, vertical down-cutting of the rivers, deep gorges of rivers, triangular facets (flatirons) and tilting of beds, have been noticed in various parts of the study area. In some basins the morphometric parameters suggest a possibility of flash floods and high discharges.
