This graphic shows factors that contributed to the top 10 high-water events measured at New York's Battery Park from 1900 to present. The water height for each event is shown here against the benchmark of MLLW (mean lower low water) averaged between 1983 and 2001. Sea level rise (about a foot since 1900) is depicted here as a component of storm surge. Although Sandy's surge peaked close to high tide, other events had even higher tide levels.
