However, high CN areas should not be combined with low CN areas (unless the low CN areas are less than 15% of the subbasin). In this case, separate hydrographs should be generated and summed to form one hydrograph.

(Moderately low runoff potential). Soils having moderate infiltration rates when thoroughly wetted, and consisting chiefly of moderately fine to moderately coarse textures. These soils have a moderate rate of water transmission. C. (Moderately high runoff potentiai). Soils having slow infiltration rates when thoroughly wetted, and consisting chiefly of soils with a layer that impedes downward movement of water, or sods with moderately line to fine textures. These sails have a slow rate of water transmission. D. (High runoff potential). Soils having very slow infitration rates when thoroughly wetted and consisting chiefly of clay sods with a high swelling potential, soils with a permanent high water table, soils with a hardpan or Gay layer at or near the surface, and shallow soils over nearly Impervious material. These sods have a very slow rate of water transmission. From SCS,TR-55, Second Edition,June 1986, Exhibit A-1. Revisions made from SCS, Sol Interpretation Record, Form F5, September 1988.
