FLO-2D
Two-Dimensional flood routing model that simulates river, alluvial fan, urban and coastal flooding.
FLO-2D can tackle any complex flooding project including:
- River overbank flooding
- Unconfined alluvial fan flows
- Urban flooding with street flow, flow obstruction and storage loss
- Overland progression of tsunami and hurricane storm surges
- Mud and debris flows
- Watershed rainfall and runoff
- Surface and groundwater interaction
- Flood insurance studies
- Flood mitigation design
FLO-2D has a number of components that enhance detailed flood routing including channel-floodplain flow exchange, loss of storage due to buildings, flow obstructions, simulation of hydraulic structures, levee and levee failure, sediment transport, simulation of hyperconcentrated sediment flows (mudflows), rill and gully flow, rainfall and infiltration. FLO-2D is a FEMA approved hydraulic model for riverine studies and unconfined flood analyses. The following descriptions provide a brief overview of the model.
FLO-2D is a combined hydrologic and hydraulic model so there is no need to separate rainfall/runoff and channel/floodplain flood routing.
