Daily water balance is done for a lake (300 acres of surface area) that is used as water supply resource for a community. During the previous 24-hr period the average inflow was 200 cfs, the average outflow (including water extracted for public supply) was 80 cfs, total precipitation was 2 in. and the pan evaporation near the lake indicated a net reduction of 0.3 in. Infiltration losses of the soil and bottom of the lake have a constant infiltration rate of 0.2 in/hr. Assume that the pan constant of evaporation is 0.70.
Determine (showing all computations):
a) Daily evaporation of the lake (in.).
b) Daily infiltration of the lake (in.).
c) Net daily change of lake's surface elevation (in.). d) Net daily change of storage volume (acre-ft).

    The water elevation of Lake Ontario is 246 ft and a surface area of 4.69x106 acres. The annual inputs and outputs to the lake are 40.0 inches of precipitation, 36.3 inches of evaporation, 3.0x104 cfs of runoff, 2.45x105 cfs of stream inflow, and 2.70x105 cfs of outflow. Groundwater flow into Lake Ontario is minimal and considered negligible in water balance. a) Make a tabulated water budget showing the inputs and outputs in metres per year and calculate the change in...

    You are performing a study of evaporation from Lake Patagonia in southern Arizona. The inflow of water is measured at a nearby USGS gauging station immediately upgrading of the lake and averages about 15.8 cubic feet per second (cfs) for a 30-day period. precipitation in the area totaled 4.5 inches during the same period. The lake has a surface area of 265 acres and you can assume the sides of the lake are vertical. At the beginning of the study...

    sovle it in understandable line please. thank you. Question 2- Surface area of a lake is 400 km' and annual precipitation is 32.5 cm. Inflow rate of stream is 2.54 m/s and outflow rate of stream is 2.67 m/s. Water surface level in the lake is increased by 22 mm during the year. Neglect the infiltration in the lake and compute the evaporation height in the lake for the related year.
