Abstract

The AA. developed relationships for post-fire bedload sediment delivery rates for spatial scales up to 117 ha using sediment yield data from 6 published studies and 2 recently established study sites. Sediment yields and sediment delivery ratios (SDRs; sediment delivered at the catchment scale divided by the sediment delivered from a plot nested within the catchment) were related to site factors including rainfall characteristics, area, length, and ground cover. Unit-area sediment yields significantly decreased with increasing area in 5 of the 6 sites in Colorado, Washington, Utah, Montana and Arizona. The annual SDRs ranged from 0.0089 to 1.15 and these were more closely related to the ratio of the plot lengths than the ratio of plot areas. The developed statistical relationships will help quantify post-fire sediment delivery rates across spatial scales in the interior western United States and develop process-based scaling relationships
