Abstract:

This report deals with investigation of risk assessment methodologies, existing in literature, pertaining to dam gates and associated operating equipment conducted in Phase I of this research. More than 60 references have been studied in detail as part of the work. Based on this, five methods have been identified as potential methods for risk assessment of dam gates. These are Dekay and McClelland 1993, Cheng et al. 1986, Lafitte 1993, Lafitte 1996, Kreuzer and Bury 1984. Dekay and McClelland 1 993 proposed a method for predicting Loss of Life LOL resulting from dam failures and flash floods. An empirical equation has been derived for LOL in terms of Population At Risk PAR, Wanning Time WT and Forcefullness of Flood Waters FORCE. Cheng et al. 1986 propose calculation of probability of failure due to any cause using Advanced First Order Second Moment AFOSM method for the formulated performance function. Lafitte 1993 proposed an equation for calculation of Reliability R in terms of probability of occurrence of the undesirable event P, and the probable extent of the damage caused D and a risk consequence factor a.
