• Table 1. Determining Erosion Condition Class. <br />Item Weighted Value <br />Soil `lovement <br />Surface Litter <br />Surface Rock Fragments <br />Pedestalling <br />Flow Patterns <br />Rills <br />Gullies <br />14 <br />14 <br />14 <br />14 <br />15 <br />14 <br />15 <br />TOTAL: 100 <br />3. For the third step, it must be determined if each item is <br />potentially present as only these items will be considered. For <br />instance, a soil having no rock coarse fragments within its <br />profile nor other potential source of rock would not be assigned <br />a zero value which would indicate a potential weighted value of <br />14. Rather, where the potential for rock fragments does not <br />exist, rock fragments are not a valid factor as shown in <br />Illustration 2 and 3. <br />I 4. In the fourth step, for those items potentially present, a <br />• description should be reviewed and a numerical value should be <br />indicated. Tables 2 through 8 indicate five magnitudes of <br />erosion activity within each of the seven items. <br />The total range of SSF values of 0 to 14, or 0 to 15, is divided <br />into five, more or less, equal classes to conform with the five <br />erosion condition classes. <br />• <br />7 <br /> <br />
