Exercise 26
- How large is the capture zone of a well that pumps 0.005 m3/s in a 20-meter-thick aquifer with a hydraulic conductivity of 5.5×10-3 m/s, and a gradient of 2.5×10-4 directed due east?
- How far down gradient it the stagnation point?
- If a contaminant spill occurs 200 meters northwest of the well, how much does the pumping rate need to be reduced to avoid drawing in contaminated water?
