Floods and Phreatic Zones


The field where I snapped this fox picture is underwater now, with the river shooting its banks and still rising through Monday morning.

Dens of fox and groundhogs are designed to keep the animals dry, yet fox in particular like to locate their dens very near water.

Shallow dens are sometimes found carved into the sides of small humps or rises in marshy areas, but these are rarely natal dens. The deeper natal dens of fox are generally found on the rises above the flood plains -- on well-drained hillsides.

The ideal spot for a pipe is deep enough to be dry from surface water, but not so deep as to be encountering the water table -- the so-called "phreatic zone".
