The k values were adjusted for volumetric rock fragments, whenever necessary, according tc <br />Table 603-5 (SCS, 1983 -National Soils Handbook). The map unit k factors are based upon <br />composition percenta ge information listed in Tab 9, Appendix 9-4, Table 9-4-3. <br />PR-05 8 Revised 01/06 <br />
