Question

6. Long Pond has a surface area of 3.5 km², and for a given month the pond has an average inflow
of 3.4 m³/s and an outflow of 2.75 m³/s. There is a 0.35 m storage change in the lake level. If a
precipitation gauge recorded 52 cm for the given month, determine evaporative loss (in cm) for
the lake during that time.
7. A swimming pool (5 m x 8 m x 3.5 m) has a small leak at the bottom. You are provided with
measurements on rainfall, evaporation, and water level on a daily basis for 10 days. As an
engineering technologist, use the water balance to determine the average daily leakage out of
the swimming pool in litres per day. Assume the pool is exactly 3.5 m deep on day 1.

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

There is a reservoir covering a 500-hectare area that has a constant draft of water pumped from it. The reservoir has a constant inflow from an upstream watershed, where the annual rainfall is 550 mm and the annual runoff is 312 mm. Over a 30-day period, the reservoir depth drops 9.5 m. During this time, there was precipitation over the reservoir of 87 mm and the total evaporation was 73 mm. What is the daily draft of water from the reservoir (in hectare-meters)?
