Summary

This bulletin published by the Department of Geology Tribhuvan University is a report on the Morphology and classification of the main stem Bagmati River. Rivers are significant geomorphic agents which can carry huge amounts of sediments and water from their catchments to depositional basins. Due course of flow they can bring various hazards such as flooding, inundation of flood plains, erosion of banks, and trigger various slope movements. To understand the nature and behavior of the Bagmati River, which is a perennial, storm and spring-fed, eight-order river of central Nepal, the planiform morphological parameters of this river were analyzed and river segments along the main stem stretches were classified into various stream types, using topographic maps, aerial photographs, and satellite imageries.
