Week 4:  High K slug tests

 

Objectives:

We will use slug tests from the deeper (semi-confined) aquifer to estimate K.  This interval has high hydraulic conductivity, is (semi)confined, and gives an oscillatory response to slug test stress.

Data sets:  slug tests from the CSUS wellfield

Excel files from the deeper water bearing interval often show an under-damped (oscillatory) response.  Two files are provided, and each file may have more than one slug test.

Assignment

Estimate hydraulic conductivity (K) in the deeper water bearing interval.  Include a methods section with appropriate references, results and discussion.  Use thesis format.
