A lake has a water surface elevation of 84.50m above datum at the beginning of a certain month. In that month the lake received an average inflow of 8.5 m³/s from surface runoff sources. In the same period the outflow from the lake had an average value of 5.6 m³/s. Further in that month, the lake received a rainfall of 160mm and the evaporation from the lake surface was estimated as 7.10 cm. 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 6,500 hectares. Assume that there is no contribution to or from groundwater storage.

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

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)?
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)
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?
9.4. A small farm reservoir behaves as two identical CFSTRs in series. Flow into the reservoir consists of runoff from pasture land having an average BOD, of 50 g/m³ and an average flow rate of 0.5 m³/s. Volume of the reservoir is 2.16 x 106 m³. If k = 0.2 d-¹ and k, = 0.35 d-¹ at 20°C, determine the dissolved-oxygen concentration if the water temperature is 20°C, the inflow is anaerobic, and steady-state conditions exist.
Solve the following: To determine the daily evaporation at lake, a USWB evaporation pan is maintained. The water level in the pan is 200mm at the beginning and is observed every day. Water is added if the water falls to about 17.5cm to the same depth during the first day. Estimate the daily pan evaporation for the 14-day period for which readings are summarized in the following table
