Geology 127 (Hydrogeology)

California State University, Sacramento

Week 13: Jacob time and distance straight-line solutions for transmissivity, hydraulic conductivity and storativity

Objectives:

Upon completion of this unit students should be able to:

  • Use the Cooper-Jacob distance drawdown method to estimate aquifer parameters.

  • Use the Cooper-Jacob time drawdown solution to estimate aquifer parameters.

  • Compare results between different methods:  C-J time drawdown, C-J distance drawdown, Theis type curve fit.
