Florida State: Dam break modelling

Project Requirement

GIS database creation and modelling (HEC-HMS and HEC-RAS) support expertise to FDEP dam break modelling projects across the state of Florida for the FDSP. In particular conducting inundation mapping and preparing Emergency Action Plans (EAP) for several high-hazard potential dams (supported by The Florida National Dam Safety Program Grant).

Project Solution

From development of bespoke geospatial software products to detailed hydrological analysis supported by ground observations, Síor Consulting provided GIS expertise to support the numerical hydraulic flood modelling of privately owned dam break scenarios.

Project Benefit

The works undertaken will allow the FDEP to understand the flooding risks (and their extent) associated with dam break scenarios for high hazard potential dams. This includes the protection of property, prevent loss of life and the ability to develop and maintain suitable emergency action plans to manage/achieve that.

Activites Completed

Geospatial-field data collection support (ArcGIS Collectors App)
Geospatial data databasing and management
Numerical modelling based of a variety of satellite data products (Digital Terrain Models, hydrological characterization, spatially and temporally distributed hydrological parameterization models)
Geospatial driven emergency evacuation plans
Drawing production, 3D-fly throughs, online WebApp presenting modelling outputs
