Name: NACCS 100-year Return Period Water Levels (meters)

Display Field: StationId

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This dataset displays the annual recurrence interval (ARI) statistics for water level at save points (~19,000) along the coast. At each point, storm surge was computed for a set of 1,150 combined tropical and extratropical storm events using the coupled ADCIRC/STWAVE models . Extremal analysis techniques were then applied to develop water level return periods at each point. The service displays the (mean) 100-year water levels at each point in meters relative to NAVD88. The dataset also includes mean water levels at 1-year through 10,0000-year return periods, and plots of the water level-ARI relationship at each point (mean and 95% confidence limits).
