Broward County Flood Viewer

The Broward County Risk Assessment and Resilience Plan, included an update to the County’s hydraulic and hydrologic models, utilizing the MIKE software suite. Models were updated with various refinements and boundary conditions to develop simulated flooding inundation maps for both 2.0-foot and 3.3-foot sea level rise scenarios under king, 20-yr, and 100-yr storm surge tidal conditions, for the 10-, 25- and 100-year rainfall storm events. This effort produced a total of 24 simulations, tabulated below. All storms simulated are 3-days in duration. The 10- and 25-yr storms have variable groundwater conditions, while 100-yr storms have a saturated groundwater condition. A rainfall change factor of 20% was applied to the all three tidal conditions for 10-yr rainfall event, under the 3.3-foot sea level rise scenario with variable groundwater. The following tool allows for visualization and comparison of the inundation results showing ground surface flooding depth in feet for the identified simulations. These results are PRELIMINARY and subject to change based on the County’s review.
