A 1220 mm-diameter ISI pan, with a depth of 255 mm, was fully filled and was used to simulate the evaporation rate of a reservoir with a surface area of 230 hectares. After 24 hours, the depth of the water dropped 7 mm. What is the daily evaporation of the reservoir and the water evaporated from the reservoir for a month (1 month = 30 days).

Estimate the constant flow rate of withdrawal from a 15 km² reservoir in a month (30days) during which the reservoir level dropped by 1 m despite an average inflow into the reservoir of 0.95 * 10 m³ /day. During the month, the average seepage loss from the reservoir was 4.5cm, the total precipitation on the reservoir was 19.5cm, and the total evaporation was 7.5cm.

The parameters of the Horton equation are fo = 7(cm/st), fc = 1 (cm/st) and the coefficient k = 4 (1/st¹). Accordingly, the total water leaking from an area of ​​2 ha to the ground in a day (24 hours) find its volume.

The level of water in the reservoir is 1.25 m. If there is a rainfall of 38 cm occurring in a month, during this period evaporation as measured by the class A pan is 32 cm. What is the level of water in m at the end of the month.
