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
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.
A lake with a surface area of 275 ha has the values of: relative humidity = 60% wind velocity at 1m above the ground = 10 kph mean barometric reading 750 mmHg es = 30 mmHg Km = 0.36 Estimate the average daily evaporation from the reservoir and the volume of water evaporated in the body in 5 days using MEYERS

15mm of precipitation fell in Akkaya reservoir in July. At the beginning of July (30 days), the surface area of the lakewas measured as 3 km². There is 9000000 m³ water in the lake before precipitation in July. At the beginning of August, the water volume in the lake was 8500000 m³. During July, Q=100 lt/s of water emerged from the reservoir. The water leaking from the ground is Q=36 lt/s throughout July. The water leaking in the same month is Q=48 lt/s. In July, 30 lt/s of water was drawn from the reservoir for 15 days to i dilate the campus area. However, in the same month, 1/3 of this water leaked and returned to the lake. During this month, the amount of water evaporating in the lake was determined as 110 mm/ m² .Calculate the flow of water coming into the reservoir as lt/s or m³/s.
The plan area of a reservoir is 1 km2. The water level in the reservoir is observed to decline by 20 cm in a certain period.
