A gage on a small (0.75-acre) urban parking lot recorded the following incremental rainfall data. Time (hr) 0 1 2 2.5 3 3.5 10 4.5 3 Rainfall (cm) 0 5 12 0.5 4.7 1.5 10 4 2.3 4.5 0 a. Determine the total storm rainfall depth (in inches). Be careful with units. b. If all of the rainfall occurs as runoff (no losses) and the time base of a triangular hydrograph is 3 hours, find the peak flow of the hydrograph in cfs. Be careful with units.

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.
