Abstract: Information about differences in surface conditions on timber harvest hillslopes is important for hydrologic modeling. We measured and compared saturated hydraulic conductivity and interrill erodibility values for different conditions found on timber harvest sites. Plots with different surface conditions were subjected to three simulated rainfall events. Conditions sampled included bladed skid roads with and without treatments, many pass skid trails, few pass skid trails, low burn severity harvest sites, high burn severity harvest sites, and undisturbed forest. Results suggest these conditions can be divided into two or three groups for modeling purposes.
