Analysis of rainfall and runoff records for a certain storm over a basin (of area 3210 km²) gave the following data: Rainfall for successive 2 hr periods: 2.5, 6.5 and 4.5 cm/hr. Direct surface discharge at the concentration point for successive 2-hr periods: 400, 1200, 4500, 7700, 12000, 10220, 8260, 3900, 838 and 400 m’. Derive the unit hydrograph for the catchment area.
A lake had a water surface elevation of 110.00m above datum at the beginning of a certain month. In that month, the lake received an average flow of 66.0m3 /s from surface runoff sources. In the same period the outflow from the lake had an average value of 66.5m3 /s. Further, in that month, the lake received a rainfall of 150mm and the evaporation from the lake surface was estimated as 7.40cm. Write the water budget equation for the lake and calculate the water surface elevation of the lake at the end of the month. The average lake surface area can be taken as 5000ha. Assume that there is no contribution to or from the ground water storage

A drainage basin has a area of 7322 km2. The average annual precipitation for this area is 909 mm. The average surface water flow at the outlet of the catchment is 21.4 x 108 m3/year and the average groundwater flow out of the basin is 94.6 mm/year. Assume trailing zeros are significant if present. Determine the annual average evaporation in mm/year. (give your answer to one decimal place)
