DAM BREAK ANALYSIS USING BOSS DAMBRK

Anila C. George, B. Thulasidharan Nair

Abstract: Dams are constructed to serve a variety of purposes such as supply of drinking and irrigation water, generation of electric power, flood protection etc… However a dam break may result in high flood waves traveling along a valley at quite high speed. The intensity of the catastrophic failure of dams varies depending on the extent of inundated area, size of the population under risk and the warning time available. The present study deals with the Dam Break Analysis of Thenmala Dam of Kerala State, India. As a part of the work, the maximum precipitation and maximum flood have been evaluated using the Gumbel’s and Clark’s method respectively. The final analysis is done using the software BOSS DAMBRK for evaluating the extent of inundation, travel time and velocity of downstream progressing water

Keywords: BOSS DAMBRK; maximum precipitation; maximum flood; Gumbel’s method; Clark’s method
