Soil Erodibility Factor, K <br />The K factor for the site soils were provided by the Steamboat Springs, Colorado office of the <br />NRCS (Vance Fulton, MRCS soil scientist, personnel communication, 1995). The average K <br />value for soil map units 66 and 68 is 0.28, for soil map units 2VC and 2VD the K value is 0.24, <br />and for soil unit 103, the average K value is 0.17. The area weighted average K value was <br />calculated as 0.25. <br />Representative Slope Length, ~ <br />The slope length is representative of the typical slope length for a watershed. It is the distance from <br />the point of origin of overland flow to the point where the slope decreases such that significant <br />deposition occurs or the flow enters a defined channel. The slope length was measured directly from <br />the 1" = 500' computer generated map. <br />Average Slope <br />The average slope is entered as a percent and is the representative slope for overland flow for each <br />watershed. The average slope was measured directly from the 1 " = 500' computer generated map. <br />Control Practice Factor, CP <br />The control practice factor is defined as the ratio of sediment loss from an area with a given cover <br />and conservation practice to that of a field in continuous fallow. The following value (Haan, et al., <br />1994) was utilized: <br />Area Condition ~ <br />Permanent pasture 0% canopy, 80 % vegetative cover 0.013 <br />c:~87Thg8~primary4nelhad.how 7/16/96 <br />
