Introduction to Viewer

The flood viewer provided herein was developed under the Broward County Risk Assessment and Resilience Plan. The viewer depicts the results of the update to the County’s hydraulic and hydrologic models, utilizing the MIKE software suite (MIKE SHE – MIKE Hydro).

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. The 10-yr and 25-yr storms have variable groundwater conditions, while 100-yr storm simulations assume completely saturated ground conditions.

Extreme rainfall change factors representing the effect of climate change as defined by the USGS and the SFWMD were applied to all simulations corresponding to future conditions (see: Extreme Rainfall Change Factors for Flood Resiliency Planning in South Florida). The following tool allows for visualization and comparison of the inundation results showing ground surface flooding depth in feet for the identified simulations.
