In Investigate 2 we had dry solid. We found more humus eroded than in Investigate3 were the solid was wet. In Investigate 2 there was more erosion of sand and clay than in Investigate 3. In conclusion we believe that erosion occurred in both Investigate but more erosion seemed to take place in Investigate 2 the dry solid.
