1. Lake Kickapoo, TX, is approximately 12 km in length by 2.5 km in width. The inflow for the month 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 seepage is estimated to be 2.5 cm. Estimate the change in storage during the month of April. (Answer 1.61 X 106 m3)
2. A city has 6 wells in operation to supply 4.5 million gallons per day. What is this volume in acre-feet? Assume pumping is equally distributed, what is the well yield from each well, in gallons per minute.
3. Determine the water level rise in an unconfined aquifer produced by a seasonal precipitation offour (4) inches. The aquifer porosity is 20%. Assume the aquifer material was completely dry and there are no other inflows or outflows form the aquifer. What would the water level rise be if the aquifer material had a moisture content of 3 5%.
4. Convert to 1000 g/m/ft^{2} to ft/d and m/s
