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.

The annual maximum flood magnitude in a river shows a mean of 170 m³/s and a standard deviation of 113 m³/s. Assuming the uncertainty can be described by a normal distribution, what is the probability that the annual maximum flood magnitude would exceed 28 m3/s? Determine the flood magnitude with a return period of 100 years.
An effective rainfall of 2 hour duration produced a flood hydrograph peak of 200 m³/s. The flood hygrograph has a base flow of 20 m³/s. If the spatial average rainfall in the watershed for the duration of storm is 2 cm and the average loss rate is 0.4 cm/hour, the peak of 2-hour unit hygrograph (in m³/s-cm up to one decimal place) is
