a
Gross erosion is on-site soil erosion potential without considering re-deposition. Net erosion is the difference between erosion and deposition processes at a given point.
b
Qualitative refers to an assessment of temporal trends, spatial patterns and/or driving factors, while quantitative refers to quantitative assessment of sediment detachment and or transport.
