Abstract Soil erosion and deposition processes play an important role influencing accumulation and long-term stability of soil organic carbon (SOC). Therefore, evaluations of landscape-scale magnitude and variability of SOC across topographically active landscapes will improve understanding about important drivers of SOC dynamics. In this study, we investigated the relationship between terrain attributes and quantity and spectroscopic characteristics of SOC for a hillslope system in Southern California. Thirteen soil cores were sampled at representative landscape positions with a history of intense erosion. We observed a strong relationship between slope, plan and profile curvature, and quantity and quality of SOC accumulation along the hillslope systems. Specifically, moderate slopes (
