Flood Risk and Subsidence Assessment

Current and projected rates of relative sea-level rise can be used to inform adaptive management, and support project planning. To provide the most accurate rates possible, Applied Coastal personnel rely on various data sets, such as local water level time-series records, GPS elevation surveys, sea-level rise projections, storm surge scenarios, and satellite altimetry data, to identify current and future flooding risks at various project scales. We utilize geologic and oceanographic expertise to assess project-specific factors affecting relative sea-level rise rates, such as ocean and coastal processes; human modifications; and vertical land movement from subsidence, faulting, and glacial isostatic adjustments.
