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 cm and m3.

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.

A certain lake has a surface area of 90km2 at the beginning of a certain month and the water depth was 92m for the whole surface area of the lake. During that month the reservoir receives an average inflow of 110 mm and 220m3 /s as rainfall and direct runoff respectively. Whereas the outflow from the reservoir was 210m3 /s as irrigation, 200mm as evapotranspiration and 300mm as groundwater recharge during that month. Find out the depth of the reservoir...

Water from 620-hectare reservoir was being pumped with a constant rate for 30 days. Compute the constant pumping rate (in cubic meter per day) if during the 30 days period reservoir level dropped 0.65 meter despite an average upstream inflow of 230,000 m3/day. During the 30 days period, the total seepage loss was 3.0 cm, the total precipitation was 16.0 cm, and the total evaporation was 10.5 cm. (1 hectare = 10,000 m2).

Part I. Indicate whether true or false (T or F). ____ Storm water detention ponds typically are designed to regulate the outflow peak rate at or below a single target value, such as the pre-development (pre-land use change) peak runoff rate for a specified return period event. Detention storage alters the peak but not the volume of the outflow hydrograph. _____ Typical rating curves for weirs are concave upward. Typical rating curves for orifices are concave downward. ____ A sediment...
