Conclusions
-
1.
The relation between the variation of the coefficient of permeability and the height of the GWL above the drainage base for free descent in a homogeneous soil below the ground surface was established.
-
2.
A relation between the coefficient of permeability and the temperature of the medium for conditions of free descent of the GWL was found which differs from the similar relation for seepage with occurrence of the free water layer above the ground surface.
-
3.
Equations were found which make it possible to perform prediction and water-balance calculations.
