Abstract

Following the 2002 Hayman fire in central Colorado and the 2003 Cedar fire in southern California, matched catchments were monitored for 5 to 7 post-fire years to determine the effectiveness of wheat straw mulch (Hayman fire only) and hydromulch in reducing post-fire runoff, peak flow rates, and sediment yields from natural rainfall. Measured runoff and sediment yields were caused by short duration high intensity summer storms at the Hayman fire and long duration winter rains at the Cedar fire. It is shown that runoff and sediment yields were more closely related : 1) to rainfall intensity than to amount at the Hayman fire; 2) to rainfall amount than to intensity at the Cedar fire. In the first post-fire years sediment yields from the catchments were similar to those measured on hillslope plots. In later post-fire years, sediment yields from the catchments were at least double the yields from hillslope plots
