Learning Goal: I’m working on a civil engineering question and need an explanation and answer to help me learn.
The unconfined aquifer shown below is situated between two surface water features. The aquifer overlies impermeable bedrock (elevation of 90 ft) and has a hydraulic conductivity of 46 ft/d. Surface water feature 1 has a water elevation of 156.3 ft and surface water feature 2 has a water elevation of 149.0 ft. The distance between water bodies is 1,680 ft. The average rate of recharge is 0.028 ft/d.
- What is the average discharge per unit width at x = 0 (in units of gal/ft/d)?
- What is the average discharge per unit width at x = 525 ft (in units of gal/ft/d)?
- Is there a water table divide? If so, where is it located?
- What is the maximum height of the water table?
- Sketch or plot (EXCEL) the water table (h(x) vs x). Indicate the scale and vertical exaggeration of your sketch/plot. A vertical exaggeration of 20:1 is recommended on the plot.
