Week 5: Time Drawdown tests- fully confined aquifer
We will use pumping tests from the deeper (semi-confined) aquifer to estimate K. We will assume that all conditions for the Theis solution are met (fully confined aquifer).
Theis type curve solution:
Fetter, Applied Hydrogeology: Theis solution, pp. 153- 156 and 169 - 173
Notes and instructions for type curve fit, Theis method:
Sample problem: Theis method
Sample problem: 10_23_aquifer test
Data sets: aquifer tests from the CSUS wellfield
Distances between wells were measured with a steel tape:
Extraction well to MW1A = 133.0 ft
Extraction well to MW2A = 138.9 ft
Extraction well to MW3A = 30.05 ft
Estimate the transmissivity (T), hydraulic conductivity (K), and storativity (S) in the deeper water bearing interval. Assume that the interval is fully confined. Include a methods section with appropriate references, results and discussion. Use thesis format.
