Geology 127 (Hydrogeology)

California State University, Sacramento

Week 12: Theis solution continued:

Using drawdown data, solving for T, K and S


Upon completion of this unit students should be able to:

  • Hand-plot field drawdown data and overlay the Theis type curve to estimate aquifer transmissivity, storativity and hydraulic conductivity.

  • Hand-plot field drawdown data and overlay the appropriate type curve to estimate aquifer transmissivity or hydraulic conductivity.

  • Prepare for the next midterm!

Homework Assignment:  Prepare for the midterm test that will be held on Wednesday Nov. 14

Examples of old tests are given below.  Use these to study for the second exam and test your comprehension of the material.  You will not be responsible for material on the old tests that we did not cover this semester.  You should also study your notes, read the book, and prepare a note card.  You will be allowed to bring two 8 1/2" x 5 1/2" note cards to the test, or fill both sides of a 8 1/2" x 11" page with any printed material.  You may use your book to look up conversion factors during the test, but not to look up equations or examples.
