Water Resources Engineering and Hydrology — Summer 2022

Enlist the methods that are adopted to evaluate the rate of evaporation.

Describe double mass curve technique to check consistency of rain gauge station data.

There are four rain-gauge stations installed on certain river basin whose normal annual precipitations amounting to 850, 520, 430 and 370mm respectively. Determine the optimum number of rain-gauges in the catchment, if it is desired to limit the error in the mean value of rainfall in the catchment to 15%.
