Movement of ground‐water
The movement of water through formations having capillary openings is generally laminar and obeys Darcy's law, at least down to very low gradients. About 1000 samples tested in the laboratory of the United States Geological Survey have coefficients of permeability ranging from 0.001 to 90,000, indicating probable velocities ranging from a fraction of a foot to a few miles in a year. The Thiem field‐method gives promising results for determining permeability. Movement through sub‐capillary openings is important but poorly understood; molecular attraction of the water offers great resistance to movement or compression.
