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.

To determine the daily evaporation at Taal lake, a USWB Class A evaporation pan is maintained. The water level in the pan is 200mm at the beginning and is observed every day. Water is added if the water falls to about 17.5cm to the same depth during the first day. Estimate the daily pan evaporation for the 14-day period for which readings are summarized in the following table.
