Noah Snyder of Boston College developed a simple, fast, automated method for using high-resolution remote-sensing data, including LiDAR, digital orthophoto quadrangles (DOQ), and aerial photography, to characterize basic yet important geomorphic parameters of rivers. The key parameters determined are drainage area, channel width, channel slope, shear stress, and expected mean sediment size (D50). Key parameters that must be estimated include Manning’s roughness coefficient (n) and other regionally-based constants.
