Abstract

This study examines how sediment and water connectivity, defined as the transfer of material from source areas, such as landslides, to receiving streams, has evolved in response to urban development. Connectivity is a key control on how surface processes transfer energy and material across a landscape, influencing drainage behavior and slope stability. High-resolution LiDAR topography from 2007 and 2021 was used to analyze the southern Cincinnati, Ohio area and to calculate and compare connectivity metrics across time periods. These results were integrated with hydrogeologic data to assess whether shifts in surface connectivity are associated with changes in landslide frequency and magnitude. The findings provide insight into the influence of urban development on surface connectivity and have implications for improved landslide hazard assessment and regional planning.
