Probability, risk and uncertainty analysis for hydrological design

It gives a framework that is financially critical for finding the exceptional designs of hydrological systems with a reduced cost in total inclusive of the project cost and the disaster mitigation cost. But there would be hardly any assessment of a decent quality damage function. Hence, errors in demonstrating the hydrologic events, incorrect model parameters, and so on may occur. Here, we will discuss a specific hydrological design that of a detention basin for studying and understanding the risk-based procedure, uncertainties, and probability analysis by following a systematic framework.

Question

i) Analysis on a flood data in a river at a station have been processed to estimate the
maximum flood for different return periods using the Gumbel's method. If the
estimated maximum flood for return periods 200 and 100 years are 600 m³/s and
450 m³/s, respectively, estimate the flood discharge for return period of 500 years.
