2.10 Figure 2.28 shows a catchiment with seven raingauge stations inside it and three stations outside. The rainfall recurded by each of these stations are indicated in the figure. Draw the figure to an enlarged scale and calculate the mean precipitation hy (a) Thiessen- mean method, (b) isohyetal method, and by (C) arithmetic-mean method. 11.2 11.7 E 8.2 13.2 10.8 14.0 10.2 10.9 6.3 9.2 5 km SCALE Fig. 2.28 Problem 2.10

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.
