Rio Verde Flood Hazard, Phoenix, Arizona

Alluvial Fan Flooding

FLO-2D v2007.06 New Features:

• Integrated ArcGIS Mapper.NET for high resolution shaped contour maps
• Option DFIRM Tool
• Levee and dam breach erosion component
• SCS curve number watershed rainfall component
• New graphical editor and mapping tools...and much more.

A FEMA approved hydraulics model for both riverine studies and unconfined alluvial fans.

A complimentary CD of FLO-2D Version 2007 is being shipped to all users who purchased the model in 2007 and 2008.

Short Courses: 

1.  Southhampton, UK:  June 16-17, 2008  "Debris and Flood Modeling"

FLO-2D is used worldwide to predict and map flood hazards including river overbank flooding, unconfined alluvial fan flooding, urban flooding, watershed rainfall/runoff, coastal flooding, tsunamis/storm surges, dam break flooding and mud and debris flows. FLO-2D routes a flood hydrograph while predicting floodwave attenuation and reporting on volume conservation.  Simulating flow over dry unconfined surfaces requires no hot starts or complicated boundary conditions.  Add flood details including levees, streets, obstructions (buildings), infiltration, floodways, rainfall, infiltration and evaporation losses, sediment transport, mudflows and more.

Update Note:  A bug involving levee tailwater calculation was recently uncovered in an older Version 2006.01 model for the dates between January and July 2006.  The bug was unknowingly corrected when the levee routine was updated in July 2006.  Make sure you are using the most recent FLO-2D update when you start a new project
