This video is about the CooperJacob (1946) straightline method of nonsteadystate pumping test analysis in confined aquifers. We will look at both the timedrawdown and distancedrawdown methods using the Oude Korendijk data from Kruseman & de Ridder (2000), and how the Transmissivity and Storativity can be calculated manually using formulas, as well as automatically in the CooperJacob XL tool in Excel.

I developed the first version of CooperJacob XL in Ghana back in 2002/2003 with the help of Edwin Dodoo. When Excel removed the feature to move data points in charts, I added the data sliders. The video shows you how to use them to adjust the best fit line to the data.

This is an educational video & part of the Hydrogeology 101 course.
