Problem 1: a) For the design of a spillway with an economic life of 100 years the accepted risk can be taken as 5%. Determine the return period of its design discharge. b) If a cofferdam with 5 years economic life of this large dam is designed with 25 years of design flood, determine the risk of this cofferdam. c) Find also the probability that the design flood of the cofferdam occurs at least 3 times during 5 years economic life of this cofferdam.
