Python code of "Analytical Groundwater Modeling"

This repository contains the Python code of the book "Analytical Groundwater Modeling: Theory and Applications Using Python" by Mark Bakker and Vincent Post, published by CRC Press.

The book is available through the publisher, at amazon UK, at amazon US or your own favorite bookstore.

All Python code of the book (one Notebook for each chapter) is available on this github site.

An erratum notebook has been added with corrections to the book.

Errata

Hello,

I finished the book. I found it to be a very educational read, certainly for someone as me with limited experience in analytical groundwater flow modelling. I believe I've found some errors in the equations/code cells. I do apologize if this comes across as pedantic, which is certainly not my intent.

1. Eq. 6.66: in the definition of $h_1$, the second term between the brackets should have a + sign instead of a - sign. This is coded correctly in the corresponding code cell.
2. Figure 6.15: to obtain this figure, the corresponding code cell should plot -Q0tot / Q and -Q1tot / Q (i.e. minus signs should be added). Additionally, the x-label on the right plot should read $r/\lambda$ instead of $r~(m)$.
3. p. 146: in the set-up of the head-specified line-sink model, the first definition of xls seems redundant?
4. p. 165: The minus sign in equation 9.48 is incorrect I believe. The definition of Qrbar in the code cell on the next page does not show this sign. Also, there is no code for the creation of the right plot panel of figure 9.8.
5. p. 187: in the code cell, qtop should be multiplied by 1000.

Kind regards,
Cas

Error in equation 2.55

Equation 2.55 on page 40 contains an arithmetic error I believe. The cosh terms should be summed, not subtracted. In the corresponding python code, this is coded correctly.

Code for legend of contour lines doesn't work anymore for MPL > 3.5.2

Matplotlib has changed the way legends for contour lines must be added at least since 3.5.2.
The code must be modified so that it works with the latest version of Matplotlib (unfortunately, the code has not become easier).
