the
top of the steel posts). Erosion associated with the underburning study
(burned in 2001) appears
significant in places. We can also
follow soil accumulation above washers and behind charred wood, and pedestal erosion under perched
logs. Slope and other factors will be accounted for by entering all grid points into the
GIS. We will check for hydrophobicity and rilling between grid points; if found, they will be
mapped and the volume of eroded soil measured.
We think the possibility of shallow or deep-seated slope failures, unless
there is an intense storm this
winter. Movement of rebar can be
measured if this happens, to quantify
this kind of erosion. Fixed photo
points, including 4 m2 top-
down pictures of the soil surface, will help to
establish
pre-fire conditions.
