DESIGN ANALYSIS FOR RIVER DIVERSION OF THE BEAS RIVER NEAR KULLU

Abstract

The dissertation topic is design analysis for river diversion of the Beas River near Kullu. The Beas River is joined by the Parvati River and the combined flow goes down stream alongside the Bhunter Airport. The river hydrology of the Beas is undergoing modification due to a dam being constructed on the Parvati River. Now in the changed scenario, it is proposed to conduct comprehensive design analysis for possible diversion of the Beas River on the downstream side of the Bhunter Airport to open up required land space for extending the runway by length of about 660 meter. The dissertation includes an in-depth critical study of river behavior and hydraulics. Study of diversion of the Beas river on the downstream side of the Bhunter Airport has been done with pilot channel of tractive force ratio method. Also the analysis of the new pilot channel has been done with ID-mathematical modeling using HEC-RAS. Modeling is the modern technique to determine both short-term and long-term river channel responses to any change in the environment. It include the analysis of sediment transport capacity of the Beas River and the excavated pilot channel
