An integrated river and floodplain model. A complete flood routing hydrologic and hydraulic model with numerous urban detail features.
FLO-2D Basic is actually the v2009 model updated and simplified free of charge distribution. It is approved for FEMA FIS studies. It is usually a good tool for Demonstrations, students, training and FIS studies. A basic license is provided for free but isn't going to include training, webinars or tech support team.
Urban flooding with street flow, flow obstruction and storage loss
FLO-2D can be a combined hydrologic and hydraulic model so you do not have to separate rainfall/runoff and flood routing. FLO-2D is really a FEMA approved hydraulic model for riverine studies and unconfined flood analyses. For a brief overview in the model components For additional information download the Basic Model or Contact Us.
The model uses the complete dynamic wave momentum equation along with a central finite difference routing scheme with eight potential flow directions to predict the growth of a floodwave more than a system of square grid elements.
FLO-2D requires two groups of data: topography and hydrology. Topography could be represented by way of a digital terrain model DTM points, contour mapping or survey data. The grid element elevations are assigned from an interpolation in the DTM points. A processor program known as the Grid Developer System GDS generates the grid system and assigns the elevations. A typical grid element size will vary from 10 ft 3 m to 500 ft 150 m. The amount of square grid elements is unlimited.
Aerial images is usually imported for the GDS as background to help you graphical editing.
The factor to accurate flood routing is volume conservation. FLO-2D tracks and reports on volume conservation. Numerical stability is linked to volume conservation then when the model conserves volume the model runs faster. Computational timesteps are incremented or decremented as outlined by numerical stability criteria.
Inflow hydrographs may be assigned to either the channel or floodplain nodes. The volume of inflow nodes are unlimited. Any ASCII data format hydrograph might be used as input. FLO-2D may perform like a rainfall runoff model and rain may appear on the flooded surfaces.
One-dimensional channel flow is simulated with rectangular, trapezoidal or surveyed cross sections. Unconfined floodplain flow is simulated in eight directions 4 compass directions and 4 diagonal directions. Overbank flow or return flow on the channel is simulated for every timestep. For detailed simulations the channel is usually larger than the grid element. Tributary inflow is unlimited. The GDS can convert HECRAS cross sections to a data file formatted for FLO-2D.
Streets are simulated as shallow rectangular channels having a curb. Streets can intersect and exchange flow with all the floodplain.
Hydraulic structures can represent bridges, culverts, weirs or another hydraulic control features. Hydraulic structures are simulated by user specified discharge rating curves or tables sent to either channel or floodplain elements. Culvert flow may occur between grid elements that aren't contiguous. Reverse flow may be possible.
Levees, road embankments and dams might be simulated by specifying crest elevations over a grid element boundary. There a several levee failure options including a comprehensive breach erosion model. Levee breaches may be initiated with fragility curves.
Floodplain storage loss because of buildings or features is usually modeled. A portion or entire element might be removed from potential inundation. Grid element flow exchange could be partially or entirely obstructed in all from the eight flow directions.
Overland flow could be simulated in small rills and gullies rather than sheet flow. The small distributary channels expand as increasing numbers of flow enters the gully. This distributary flow adds to the time of focus on alluvial fans.
Limiting Froude numbers is usually assigned for the channels, streets and floodplain grid elements. When the limiting Froude number is exceeded in a very particular grid element, the model will heighten the roughness value to suppress numerical surging. It is efficient for that model flood routing to calibrate n-values for reasonable Froude numbers.
Text output is written to ASCII files. The Post-processor MAPPER program creates shaded contours, line contour or grid element flow depth plots and hazard maps. Flood damages may be assessed along with the FLO2D output might be viewed as being a flood animation. MAPPER will even automatically generate shape files that could be imported straight away to ArcGIS. A DFRIM tool can be acquired for FEMA FIS studies. A high resolution, ArcGIS integrated mapping program can be available.

Barnard Creek is often a completely urbanized alluvial fan which has a small debris basin with the fan apex. FLO-2D was used on delineate the possibility water flood and mudflow hazard within the fan. Streets, buildings and also the debris flow overflow were simulated. The various flood scenarios that may be simulated include water flooding, rainfall, mudflow, and rainfall and mudflow.
A consulting firm conducted an alluvial fan rainfall/runoff study above a proposed increase in Las Vegas, Nevada. Rainfall was simulated inside the upper basin and runoff was routed for the development site. This project represents an illustration of simulating the hydrology in the combined basin and fan complex.
Flows inside California Aqueduct were simulated by using a trapezoidal channel as well as a uniform slope. The channel was represented by 97 500 ft grid elements. Knowing the design discharge and also the channel geometry, slope and roughness, the flow hydraulics may be compared while using analog strategy to Mannings equation for steady, uniform flow. FLO-2D correctly predicts the flow depth and velocity.
Monroe Creek bisects a sizable alluvial fan in central Utah. There can be a significant availability of boulders through the upstream watershed. The Corps of Engineers used FLO-2D to conduct an unconfined flood simulation of overbank flows. Rectangular, trapezoidal and natural shaped cross sections were chosen to represent the channel geometry. Overbank flooding and return flows on the channel were simulated to delineate the flood hazard.
The Middle Rio Grande from Cochiti Reservoir to Elephant Butte Reservoir 173 miles has been modeled by way of a joint project with the Corps of Engineers, Bureau of Reclamation and Fish and Wildlife Service. A portion on the entire reach is provided to show the cross section routine inside FLO-2D model. The reach from San Acacia Dam to San Marcial USGS gage about 40 miles is presented. Levees are simulated.
The Rogue River FLO-2D project in Oregon was developed by way of a consulting firm. The 15 mile reach of river includes numerous split channels and old meander bends. The floodplain was mined for gravel plus a number of deep gravel pits are a part of channel-floodplain interaction. A weir is identified as the channel outflow and water surface control for that lower end with the system.
An alluvial fan flood hazard delineation study was conducted above a casino resort. Flows in the alluvial fan were collected at railroad berms and directed into culverts which could overtop the railroad embankment. The culvert outflows were directed with the casino. A concrete channel principal purpose is to collect the flows upfan with the casino and convey them laterally throughout the fan. Sediment transport was analyzed to determine the opportunity loss of channel conveyance caused by sediment deposition. Flow runup from the channel became a design consideration. The Desert R

Abstract: Overland floodwave growth of ocean storm surges from hurricanes and fast rising tsunami waves may be simulated using the FLO-2D two-dimensional flood routing model. Ocean surge flooding may be simulated by assigning water surface stage and duration towards the coastline grid elements. FLO-2D can be a volume conservation model that's effective for analyzing riverine or unconfined alluvial fan flooding, but it also can simulate storm surges through coastal towns with detailed resolution. Various ocean storm surges were simulated for that City of Waikiki, Oahu, Hawaii employing an existing FLO-2D watershed model. The results illustrate which the area of inundation is usually a function of both wave height and duration because they progress throughout the downtown Waikiki area and to the Ala Wai Canal that bisects metropolis.
