APPLICATION OF UNIT RESPONSE FLOOD ROUTING THEORY TO A LINEAR DISTRIBUTED PARAMETER MODEL (CHAMBAL BASIN - MADHYA PRADESH)

Abstract

The proposed study is aimed at developing a suitable hydrologic model for the 8,800 square miles natural catchment of Chambal River in Madhya Pradesh, contributing to the Gandhi Sagar Reservoir. A J3near distributed parameter model has been detailed for simulating the catchment action, i.e. starting from the observed rainfall upto prediction of the reservoir levels at the Gandhi Sagar Reservoir. This has been achieved by di-viding the catchment into five sub-basins in the upper reaches of the tributaries, keeping view, the drainage characteristics. and in between the outlets of the sub-basins and upto the Gandhi Sagar Reservoir, the catchment is termed as interme-diate sub-basins-divided in six parts. Suitable input functions are separately defined for the subvi basins and Intermediate sub-basins. Attempts are made to develop relationships between rainfall excess/41 - index and rainfall intensity and its duration. These relationships can be of great use for prediction purposes.
