The procedure of a preliminary study on soil permeability is described. Water was applied to soil cores at their initial field soil moisture content in such a way as to simulate natural conditions. Data are presented showing variation of transmission rates and percolation rates with initial field soil moisture content for the topsoil and subsoil of Muskingum silt loam and Keene silt loam. Some comparisons were made with transmission rates and percolation rates obtained by hydrograph analysis and soil moisture changes of small watersheds under natural conditions. The data indicate considerable replication appears necessary to obtain average representative values by the core method. Even when sufficient replication establishes significant values, core data must be applied with caution and preferably in the light of watershed performance. Potential infiltration rate curves are established based on transmission rates aid soil moisture changes. The use of such curves for estimating surface supplies to runoff is indicated.
