Block 6
The erosion condition composite SSF score for this site was 10, which placed it in the
Stable erosion class. The tabulated results for this survey are shown in Table 7. In 2002 gullies
on the north facing slope were repaired. Some gullies that were not repaired on the north facing
slope have grown in size. No corrective measures are planned as a result of the inventory.
