Examples of different type of high-water marks
Detailed Description
Examples of different type of high-water marks (HWMs) that have the potential to be identified within high-resolution orthophotographs collected using unmanned aircraft systems (sUAS). Panel (A) shows a wash line formed when material is washed down the bank and/or laid over, panel (B) show a mud line depostied by the flood, panel (C) shows a debris line deposted by the flood, and panel (D) show a cut line caused by erosion.
