Abstract:
Wildfires often produce large increases in runoff and erosion rates (e.g., Moody and
Martin, 2009), and land managers need to predict the frequency and magnitude of postfire
erosion to determine the needs for hazard response and possible erosion mitigation to
reduce the impacts of increased erosion on public safety and valued resources. The Water
Erosion Prediction Project (WEPP) hillslope erosion model uses parameters based on
field measurements to calculate the interrill and rill components of erosion (Nearing et al.,
1989). Since rill erosion is the dominant hillslope erosion process in burned forests
(Pietraszek, 2006), Robichaud et al. (2010) used simulated runoff experiments to compare
rill erosion rates among unburned and burned forest plots in the western U.S. These
experiments provided measurements of the magnitude of rill erosion in burned areas as
compared to rates in unburned areas and also were used to calculate the rill erosion
parameters needed for accurate prediction of post-fire erosion rates.
