Based on the assumption that some annual flow data fit the normal probability distribution, the statistical parameters (mean, standard deviation, and skewness coefficient) for the annual flow data were respectively determined to be 750 m3/s, 110 m3/s, and 0.0.

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.
