The daily record of rainfall over a catchment area is 0.2 million cubic meters. It has been found that 80% of the rainwater reaches the storage reservoir and then passes over a rectangular weir. What should be the length of the weir, if the water is not to rise more than 402.5 mm above the crest? Assume suitable value of coefficient of discharge for the weir as 0.62.

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.
