Data from NOAA’s Sewell’s Point tide gauge in Norfolk (Hampton
Roads) was used for the localities that comprise the region known as the Peninsula. NOAA’s Windmill Point and Kiptopeke tide gauges were used for Accomack and Northampton Counties, respectively. Tidal records from a 19-year period (roughly one tidal epoch) were extracted and the data were
analyzed for the frequency of water levels at topographic elevation increments of one foot (NAVD88).
Based on the 2017 Intermediate-High numbers with subsidence accounted for elevations of 2.08 feet for
2050 and 6.06 feet for 2100 were added to the tide gauge record to model future flood frequencies. The modeled data was re-analyzed for the frequency of water levels at elevation intervals of one foot (NAVD88). |
