A catchment has seven raingauge stations. In a year the annual rainfall recorded by the raingauges are as follows: Station P = 130.0 cm; Station Q = 142.1 cm; Station R = 118.2 cm; Station S = 108.5 cm; Station T = 165.2 cm; Station U = 102.1 cm; and Station V = 146.9 cm. For a 5% error in the estimation of the mean rainfall calculate the minimum number of additional stations required to be established in the catchment.

The plan area of a reservoir is 1 km². The water level in the reservoir is observed to decline by20 cm in a certain period. During this period the reservoir receives a surface inflow of 10 hectare-meters, and 20 hectare-meters are abstracted from the reservoir for irrigation and power. The pan evaporation and rainfall recorded during the same period at a near by meteorological station are 12 cm and 3 cm respectively. The calibrated pan factor is 0.7. The seepage loss from the reservoir during this period in hectare-meters is

6- Maximum annual rainfall depth data are fitted with a distribution that is positively skewed (i.e., it has a longer tail to the right). If the mean value for the distribution is 4.22 in, then the rainfall depth with return period 2 years will be (use the next page table): (5 p) (A) Strictly less than 4.22 in (B) Equal to 4.22 in (C) Strictly larger than 4.22 in (D) None of the above
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)
Solve the following questions of hydrology analyze properly and show complete solution.
A reservoir had a water surface elevation of 110 m above the datum at the beginning of the month. In the same month, the reservoir received an average inflow of 7.5 cms (m3/s) from surface runoff sources. For the same period, the outflow from the reservoir had an average value of 5 cms. Further, in the same month, the reservoir received a rainfall of 180 mm and losses due to evaporation of 5 cm. Assume the area of the lake is 50 km2 acres and assume no contribution from groundwater storage. What is the water surface elevation of the reservoir after the month?
