The goal of this project was to develop rapid watershed assessment methods to estimate channel stability and sediment transport potential using high resolution terrain data Light Detection and Ranging-LiDAR to support US Army Corps of Engineers USACE watershed planning. This project developed a suite of tools based on advanced remote sensing technologies LiDAR that use off-the-shelf, high-resolution terrain data to rapidly assess watershed condition at the channel, floodplain, valley, and watershed scales. The widespread availability of high-resolution terrain data provides an opportunity to assess watershed conditions in great detail over large spatial extents. For this project, a channel assessment method was developed using a new LiDAR Hydraulic Geometry Relationships HGR-based approach for developing regional curves.
