This resource provides a wide range of information about geomorphology, hydrology, and sediment dynamics. One key aspect is a description of a methodology for delineating a Lateral Erosion Envelope (LEE) around intermittent degraded streams (arroyos). This method focuses on empirically derived bank retreat equations based on bank material and incision depths to create erosion hazard zones. Various methods for defining geomorphic parameters are suggested. The LEE product includes only surface areas.
