CS(AR)-23/98-99 : Estimating hydrological parameters for water balance studies in Tambaraparni river basin, Tamil Nadu

Abstract

A study has been conducted to do the water balance of the Tambaraparni river basin. Tamilnadu. Various components of water balance have been estimated and presented in this report. To estimate these components, the process estimating module of SWRRB, a model developed by USDA has been employed. The model was used to assess the futuristic scenario of water availability in the basin by simulating the water balance components. A weather generator model has been used for simulating the components. The study provided some insight into the hydrology of the basin and assessment of different water balance components of the one of the sub basins, Pachaiar of Tamabaraparni river basin. having an area of 246.21 sq. km The estimated values of various hydrological processes in the basin would be useful for planning better management practices in the basin.
