VDM Dewolfe, V: Debris-Flow Erosion Control Treatments After Wil

Erosion control techniques such as seeding, mulching and installation of log erosion barriers (LEBs) are popular methods for reducing erosion of hillslope material from steep terrain burned by wildfire. These types of erosion control can reduce dry ravel and the erosive power of runoff induced by precipitation on bare burned slopes. The heavy runoff produces frequent rilling and sheetwash erosion, which conveys water and fine soil material to the main channel, both of which are integral to debris-flow initiation and increases in volume through sediment bulking. Often the three treatment techniques are used in combination to achieve optimal erosion control. However, the methods by which the treatments are applied, and the relative concentrations applied must be optimized for effective erosion control in a particular area.
