For a given month (30 days): a 20 Km2 lake has 5 m3/s inflow, 4 m3/sec outflow, and total storage increases of 1.2X106 m3. Monthly precipitation on the lake is 12 mm. Assuming the infiltration is insignificant for the lake, determine the evaporation loss in (mm) from the lake.






























Part. 2 (2.5 marks): The evaporation rate from the surface of a 160 m2 lake is 436 m/day. Estimate the depth change in the lake in feet during a 1-year period if the net inflow to the lake is 25 mm3/sec.

A lake has a surface area of 2 km2. During the month of June (30-day), the inflow rate (I) to the lake was 1.0 m3/s and outflow rate (Q) from the lake was 0.75 m3/s. During this period, the total amount of precipitation (P) on the lake surface was 10 cm, the total amount of evaporation (E) was measured at a nearby pan as 15 cm. (The pan coefficient is 0.7) Calculate the storage change (ΔS) for this period in...

4. [20] Lake Kickapoo, TX, is approximately 12 km in length by 2.5 km in width. The inflow for the mouth of April is 3.26 m3 /s and the outflow is 2.93 m3 /s. The total monthly precipitation is 15.2 cm and the evaporation is 10.2 cm. The net seepage out of the lake is estimated to be 2.5 cm. Evapotranspiration and runoff can be neglected. Estimate the change in storage during the month of April.

3. [20] You have been conducting a water quality study of Lake Arjun, which has a surface area of 8.9 ×105 m2 . The average depth of the lake is 9 m. The lake is fed by a stream having a flow rate of 1.02 m3 /s and a phosphorus concentration of 0.023 mg/L. Runoff from the homes along the lake adds phosphorus at an average annual rate of 1.25 g/s. The river flows from the lake at a flow...
