DA River in the Thunder Bay area experienced peak floods of 2600 ft/s and 3000 ft³/s respectively for the return period of 15 and 30 years. The flood peak data on this river normally follows the normal probability distribution. You, as a novice engineer, are asked by your supervisory engineer to estimate the peak flow on this river for the return period of 70 years.

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.
