Direct runoff from a flood over a basin of area 50 hectare was observed as 25000 m³ during a storm. The equivalent depth of rain fall over the basin was 97 mm. The time distribution of the rain fall during the storm is given below. Determine the O-index for the storm. Time (hr.) 0 1 2 3 4 5 67 Rainfall (mm) 0.0 6.0 11.0 34.0 28.0 12.0 6.0 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.
