Question 06 The evaporation from a lake is to be calculated by the Water balance method. Inflow to the lake occurs through three small rivers A (15.0 m /s), B (20.0 m³/s), and C (17.0 m³/s). The outflow occurs through river D (45.0 m³/s). Calculate the evaporation from the lake surface during summer (May-August) if the water level was at +571.04 m on May 1 and +571.10 m on August 31. The lake surface area is 9536/100 km?. The precipitation during the period was 9536/90 mm.

QUESTION 1 (C01:PO1) A flood control reservoir has an average surface area of 5 km2. During the raining season, the reservoir receives an average daily inflow rate 2.592 x 106 m/day. If the average monthly rainfall and evaporation are 500 cm and 80 cm respectively, estimate the time taken for the increment of water level of 15 m in the reservoir if the daily outflow rate is controlled at 1.25 x 10 m/day. Neglect seepage in your estimation. (C3-C4)
