What FLO-2D does
FLO-2D Software, Inc. is a privately held, Arizona-incorporated software vendor specializing in two-dimensional flood routing and sediment transport modeling. The company builds, distributes, and supports FLO-2D Pro, a hydrodynamic simulation engine whose underlying model was conceptualized in 1987 to predict mudflow hydraulics and has since been extended to urban flood mapping, alluvial fans, coastal flooding, dam and tailings dam breach (including two-phase flow), and flood assessment for solar and wind power sites. Model construction is performed through FLO-2D Plugin (Gila), a Python-based, open-source QGIS extension that stores project data in a GeoPackage/SQLite database and integrates with HEC-RAS, EPA SWMM v5, FEMA Hazus, GDAL, LiDAR, NOAA Atlas 14, and NEXRAD radar inputs.
The company monetizes primarily through subscription software licenses sold direct via its e-commerce storefront ($2,495 initial, $1,495 annual renewal, unlimited elements and stations per site) and complementary high-margin training revenue from international 2-5 day short courses ($8K-$15K), a modular library of 28+ topic-specific training packages, and short online courses (e.g., $650 Advanced Dam Breach). FreqPlot, a $50 standalone frequency-analysis utility, and ancillary visualization and execution tools (FLO-2D MapCrafter, FLO-2D FLORunner) round out the offering.
FLO-2D serves three primary use-case verticals: engineering consultants and hydrologists, mining companies and dam operators, and municipal water resources departments. Distribution is direct-to-customer, primarily through the company's e-commerce site and global short courses organized via local partner institutions, with supporting go-to-market via multilingual YouTube channels (English, Spanish, Portuguese, Italian), webinars, a structured documentation portal, and email newsletters. The firm is founder-operated, headquartered in Nutrioso, Arizona, with a 1-10 employee footprint and no disclosed external institutional funding.

Product offeringCore offering
FLO-2D develops and sells FLO-2D Pro, a two-dimensional flood routing model conceptualized in 1987 for predicting mudflow hydraulics and adapted for urban flood mapping, alluvial fans, coastal flooding, dam and tailings dam breach, and flood assessment at solar and wind power sites. The company also offers supporting tools including the open-source FLO-2D Plugin (Gila) for QGIS, the FreqPlot frequency analysis tool, FLO-2D MapCrafter and FLO-2D FLORunner utilities, and a catalog of training packages and international short courses.
Product overview
FLO-2D Software offers a suite of flood modeling products centered on the FLO-2D Pro 2-D flood routing engine. The core product is FLO-2D Pro, a comprehensive flood simulation tool for urban flood mapping, dam/tailings dam breach, alluvial fans, coastal flooding, and mud/debris flows. It is built and managed through the FLO-2D Plugin (Gila) for QGIS, a free open-source Python-based GIS plugin that serves as the primary interface for model construction, data processing, and result visualization. Supporting tools include FreqPlot (frequency analysis), FLO-2D MapCrafter (output mapping), and FLO-2D FLORunner (model execution). The company also provides an extensive library of modular training packages covering topics from getting started to advanced tailings dam two-phase flow modeling, plus scheduled international short courses. Pricing is subscription-based at $2,495 initial plus $1,495/year renewal.

FLO-2D competitors and assessment
Company assessmentEmerging players
- HydroCAD: HydroCAD is a hydrology and hydraulics modeling tool widely used by civil engineers for stormwater and small-watershed analysis. It is a smaller, more focused alternative to FLO-2D in the engineering-consultant segment, particularly for site-scale stormwater design.
Broad incumbents
- Autodesk InfoWorks ICM (formerly Innovyze): Autodesk's InfoWorks ICM is an integrated catchment, river, and 2D flood modeling platform serving water utilities and engineering consultants. It is a broader incumbent alternative to FLO-2D's urban and storm-drain modeling features, typically sold into large municipal and water-utility procurements.
- DHI (MIKE Powered by DHI): DHI's MIKE suite is a comprehensive collection of coastal, marine, river, and urban water modeling tools (MIKE 21, MIKE URBAN, MIKE FLOOD) used by the same engineering consultant and municipal customer base. It is a much larger incumbent offering overlapping 2D flood and storm-surge capabilities that compete with FLO-2D at the higher end of the market.
- HEC-RAS (US Army Corps of Engineers): HEC-RAS is a free, government-maintained 1D/2D riverine and dam-break modeling suite from the U.S. Army Corps of Engineers. FLO-2D explicitly imports HEC-RAS geometry files, and HEC-RAS is the default zero-cost alternative FLO-2D competes with in the same engineering workflows.
- Bentley OpenFlows (formerly Bentley HydroCAD / CivilStorm): Bentley's OpenFlows (CivilStorm, SewerGEMS, PondPack) targets the same municipal stormwater and flood-modeling workflows as FLO-2D's urban features. As part of Bentley's broader iModelHub infrastructure-software portfolio, it competes for the same municipal and engineering consultant budgets.
Direct peers
- Aquaveo SMS (Surface-water Modeling System): Aquaveo's SMS is a GUI-driven surface-water modeling environment supporting 2D hydraulic, coastal, and sediment transport models. It competes with FLO-2D Pro in riverine, coastal, and dam-break modeling, serving a similar engineering consultant and academic user base.
- Deltares Delft3D: Delft3D is an open-source 2D/3D hydrodynamic and morphodynamic modeling suite from Deltares, used by researchers and engineers for river, coastal, and urban flooding studies. It overlaps with FLO-2D's flood routing and sediment transport capabilities and serves a comparable technical audience.
- EPA SWMM (and XP-SWMM / InfoSWMM commercial variants): EPA SWMM is the open-source standard for urban stormwater and sewer modeling, which FLO-2D's urban/storm-drain module explicitly integrates with via SWMM.INP import/export. Commercial wrappers such as XP-SWMM extend SWMM with 1D/2D coupling, competing head-to-head with FLO-2D's urban flood mapping capability.
- TUFLOW: TUFLOW is one of the most widely used 1D/2D hydraulic and flood modeling software packages globally, with very similar target users (engineers, hydrologists, consultants) and use cases (urban flood, coastal, dam break). It is the closest direct competitor to FLO-2D Pro in the 2D flood routing category.
Regional players
- Hydronia (Iberica / International): Hydronia distributes hydraulic and hydrology software products (including river and 2D modeling tools) with strong presence in Latin America and Europe. It is comparable to FLO-2D in the 2D flood modeling niche but competes more directly in Ibero-American markets where FLO-2D also runs Spanish/Portuguese training courses.
