Erosion rates
Rationale : Erosion appears significant in places. Total
nutrient loss will be measured in soil.
Erosion measures are needed to determine the proportion attributable to
volatilization. The focus on erosion will
increase if preliminary assessments suggest a large proportion of losses are in erosion.
Quantify erosion after individual storms by measuring changes in position of
washers (placed before significant rains in October 2002) relative to the top of
the steel posts.
Develop techniques to
assess rill erosion, accumulation of soil behind charred wood, pedestal erosion
under burned wood and perched logs, and hydrophobicity.
Develop a GIS model to
analyze data taking into account slope and other factors.
