Question

Use the diagram of the unconfined (water-table) aquifer on the next page for the following questions. A. This area receives 116 cm/yr of rainfall. It is not vegetated. Evaporation, as measured 2. by pan experiments, totals 90 cm/yr. The hydraulic conductivity of the aquifer unit is homogeneous and isotropic, and has been measured at 0.32 f/day. Where is the groundwater divide in the unconfined aquifer? B. What is the maximum height of the water table? C. What is the water table height at a distance of 220 m from the lake on the left? Make a plot of the water table height (head) vs. distance. You may use graphing fware or graph paper, but be sure that you label your axes. m冫 h 65m auay 60m

    For an unconfined aquifer with uniform recharge problem, the initial water table is 10 meters above the confining layer. Given recharge rate from rainfall 50 cm/year, pumping rate 1000 m^3 /day, aquifer hydraulic conductivity 10 m/day, calculate the effective radius and calculate steady-state groundwater head at 100 meters away from the pumping well.

    An unconfined aquifer has an initial thickness of 15.80 m. The initial water table is horizontal and located 4.7 m below the ground surface. A 15-cm diameter well is driven to the bottom of the aquifer and pumped at 3000 Lpm until steady state conditions are achieved. At this time the drawdown at the well is 4.35 m and the drawdown in an observation well located 850 m away is 0.12 m. (a) Make a sketch that defines the problem....
