and river network data (North Fork and Upper Eel Rivers). Conducted air
photo analysis of mass wasting features for multiple photo years.
Conducted statistically based field studies to map, classify, and
quantify sediment sources, including mass wasting, bank erosion and
gullying for the Gualala, Van Duzen, North Fork Eel, upper Eel, South
