Lecture-7-Estimation and Modelling of Melt Runoff.

Abstract

snowmelt is a vital component of the streamflow for the Himalayan river system. The spring and summer runoff, comprising mostly snowmelt, is the main source of water for irrigation, hydroelectric power and drinking water supply. Therefore, estimation of snowmelt runoff is very essential for regulating the flow from the reservoirs, estimating design flood for the hydraulic structure and other water resources development activities in the Himalayan region. The development of suitable modelling approach of this valuable source of water supply is, therefore, of utmost important for management and utilization of water resources in the Himalayan region. In spite of the importance of snowmelt runoff in the Himalayan water resources, very limited efforts have been made for modelling of snowmelt runoff.
