Everything you need for a citable hydrologic analysis
From selecting a boundary on the map to issuing the final report, every iFloodSim feature is organized around the real workflow of an engineering project.
Eight capabilities, one continuous workflow
iFloodSim features are not a checklist — they're the stages of a single engineering run, from the moment you draw a boundary to the moment you hand over a stamped report.
Hydraulic solver engine
The computational core — a GPU-accelerated 2D surface-flow solver built for engineering-grade accuracy.
- GPU Smart Solver for 2D surface flow
- Physically based runoff modeling using real soil texture
- Continuous numerical-stability monitoring on every run
- Mass-conservation error reported every run
Map & site input
Every analysis starts with precisely selecting the project boundary.
- Search an address or draw a free-form polygon
- Auto-load surrounding buildings & streets
- Boundary-stream detection with adjustable radius
- Live sync with nearby public stream gauges
Storm configuration
Define the rainfall scenario with engineering precision.
- Standard storm return periods, 2 to 100-year
- Manual intensity, duration & hyetograph control
- Historical rainfall archives & regional forecasts
- Recorded rainfall maximum shown for comparison
AI assistant
From identifying the problem to suggesting a fix, in one step.
- Auto-detect critical points by depth & velocity
- Deterministic mitigation layouts per point
- Layouts validated against safety guards
- Comparative simulation & ranking of best options
Watershed & drainage
Understand the hydrologic context beyond the parcel boundary.
- Automated watershed delineation from the elevation model
- Time-of-concentration & longest flow path
- Local runoff vs. upstream stream overflow
- Percent impervious & dominant soil group
Sediment & water quality
First-pass screening of runoff's environmental impact.
- TSS, phosphorus & nitrogen load estimates
- Soil-erosion risk map over the 3D model
- Sediment delivery ratio & erosion area
- Suggests bioretention, swales & inlet control
3D visualization
See the result, don't just read it.
- Depth, flow path & erosion as separate layers
- Depth-threshold slider for a risk range
- Free rotate, tilt & pan the 3D city model
- Time-based replay of the full storm event
Reporting & collaboration
Output ready to hand directly to a client or permitting authority.
- Executive PDF with summary, tables & conclusion
- Model confidence score & full source record
- Unique simulation ID for tracking & reproducing
- Add proposed infrastructure & re-run
Every number in the report is traceable
Instead of one definitive number, iFloodSim reports the confidence level of each input source — terrain, soil, land cover, rainfall — separately, so the engineer knows exactly what to rely on and where a field visit is still needed.
- Full volumetric balance of rainfall, infiltration, runoff, and final storage per run
- Continuous numerical-stability monitoring to ensure a convergent solution
- Full record of the source, status, and resolution of every data layer in the final report
