The area shown in Fig. below is composed of a square plus an equilateral triangular plot of side 20 m. The annual precipitations at the rain-gauge stations located at the four corners and center of the square plot and apex of the triangular plot are indicated in the figure. Determine the area of the polygon corresponding to each station as per Thiessen method. Estimate the mean precipitation (cm) over the area by Thiessen polygon method. Estimate the mean precipitation (cm) over the area by arithmatic mean method. Calculate the percentage variation between these two methods considering the Thiessen polygon value as the base value. Write your answers correct to two decimal places. Please upload your own handwritten answer in dropbox. 65 cm 15 km M A 50 cm D 85 cm E 72 cm 15 km B 70 cm C 75 cm

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.
