A mathematical analysis of the percolation test is presented with both capillary and gravity flow potentials considered. A relation between percolation rate, capillarity, hole shape, and permeability is developed. Laboratory percolation tests qualitatively support the analysis. Field percolation tests show no correlation between percolation rate, permeability, or position of the water table. The percolation test seems to be an unreliable method of determining the water absorption capability of a soil deposit.
