Quantitative measure of a drainage area half-size:
r_e = \sqrt{\frac{A_e}{\pi}} |
It makes a physical sense of a geometrical average distance from well to the drainage area boundary.
For a circular-shape drainage area with centred well it makes a direct sense of a distance between a well and drainage area boundary.
