Adjust the half foot increment map layers (circle) to view the potential inundation impacts for each year increment. Compare inundation levels to local relative sea level rise scenarios. These new scenarios were developed by the Sea Level Rise and Coastal Flood Hazard Scenarios and Tools Interagency Task Force, jointly convened by the U.S. The agency's sea level rise information page puts the number at 80 meters — some 262 feet. The derived thresholds used here provide a national definition of coastal flooding and impacts for quantifying and communicating risk. Figure 5. Annual occurrences of tidal flooding—exceeding local thresholds for minor impacts Flooding behind levees is only depicted if breaks in elevation data occur or if the levee elevations are overtopped by the water surface. Note: We do not show the low scenario as it is a continuation of the current global trend since the early 1990s and has been determined to have a low probability of occurring by 2100. Washington – Eastern and southern Puget Sound counties remapped with new elevation data. Sea Level Rise simulations are not available above the 6FT level. More precise data gathered from satellite radar measurements reveal an accelerating rise of 7.5 cm (3.0 in) from 1993 to 2017,: 1554 which is a trend of roughly 30 cm (12 in) per century. (Suitable for coastal areas and ocean bathymetry only), For complete and larger view, subscribe to. By 2200, the 0.3–2.5 meter (1.0–8.2 feet) range spanned by the six Interagency GMSL scenarios in year 2100 increases to about 0.4–9.7 meters (1.3–31.8 feet), as shown in Table 12.5. Water levels are relative to Mean Higher High Water (MHHW) (excludes wind driven tides). The elevation is zero for the sea level. The purpose of this map viewer is to provide federal, state, and local coastal resource managers and planners with a preliminary look at sea level rise and coastal flooding impacts. Areas with a high degree of uncertainty represent locations that may be mapped correctly (either as inundated or dry) less than 8 out of 10 times. All locations - Source land cover data updated from 2006 to 2010. The inundation areas depicted in the Sea Level Rise tab are not as precise as they may appear. A large fraction of the Earth’s fresh water is frozen: It’s stored in glaciers all around the world, and in both the Greenland and Antarctic ice sheets.When this ice melts or calves off, the water flows into the oceans and sea levels rise.If all glaciers and ice sheets melted, global sea level would rise by more than 195 feet (60 meters). Levees and leveed areas displayed. Note: We do not show the low scenario as it is a continuation of the current global trend since the early 1990s and has been determined to have a low probability of occurring by 2100.
