Tools for Inlet Geomorphic Mapping: An Overview and Application at East Pass, Florida and Fire Island Inlet, New York

Abstract: The purpose of this Coastal and Hydraulics Engineering Technical Note (CHETN) is to highlight emerging tools for inlet geomorphic mapping and describe the workflows used to implement the tools. The Coastal Inlets Research Program (CIRP) maintains the US Coastal Inlets Atlas, which houses technical information (e.g., physical processes, navigation channel position, federal authorization for management purposes) on tidal inlets. Future expansion of the Atlas should include ready-made products that address a call from coastal inlet managers and practitioners to map inlet geomorphic change and features more accurately. The methods and workflows demonstrated in this document represent the first step towards expanding the US Coastal Inlets Atlas.
