SLOSH Model Results at 30, 60, and 90 cm
For each sea-level rise scenario, the size of each flood-risk zone is larger than at present. Simply put, sea-level rise mimics the effects of stronger storms in this regard, because higher initial sea levels allow storm surges to build in height and penetrate further inland. Change is most noticeable where land slopes gently inland in the southern portions of Hampton Roads, such as the Dismal Swamp region in southern Chesapeake. Results are mapped by category and tabulated by land-cover class, below. Although the land-cover distribution of Hampton Roads will not remain static over the next century, the following tables show which land-cover categories currently occupy the at-risk areas. Land-cover data is taken from the USGS 2000 National Land Cover dataset.
