Integrating storm surge modeling with traffic data analysis to evaluate the effectiveness of hurricane

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 6,   Pages 1301-1316 doi: 10.1007/s11709-021-0765-1

Abstract: The Advanced Circulation (ADCIRC) model was applied to simulate storm tides during the hurricane eventModel validations indicated that simulated pressures, winds, and storm surge compared well with observationsModel simulated storm tides and winds were used to estimate the area affected by Hurricane Irma.moderate storm tides (maximum about 2.5 m) and maximum wind speed about 115 mph were shown in both modelTraffic data were used to analyze the evacuation traffic patterns.
