This tool provides projections and analysis of high-tide flooding days at the locations of tide gauges. If a tide gauge does not exist at the desired location, analysis from the closest tide gauge can provide useful information. However, it is important to consider the potential impact of local factors that can differ even over short distances such as land subsidence.
You can select a location in two ways:
- Select a location from from the dropdown menu displaying the current location name. The locations can be searched by typing in this field.
- Select a location by clicking on the map. Note that the map can be hidden once the desired location is chosen using the switch beneath the location name.
The methodology used to produce the high-tide flooding projections in this tool follows the process developed by Thompson et al. (2021). The method has been updated to incorporate the most recent sea-level rise scenarios from the 2022 Interagency Task Force report and applied to any location within the U.S. and its territories for which there is sufficient tide gauge data.
