QFAT01 Flow Estimator QGIS 4 compatibility
Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Estimate open-channel flow and WSL from DEM cross-sections, design-channel shapes, and manual/custom XS profiles.
About
- Estimate Q or WSL using Manning's equation from DEM, design-channel, or manual/custom XS inputs. - Sample DEM cross-sections from a user-drawn line and report A, P, R, velocity and freeboard. - Use SI and US units for common hydraulic inputs, outputs and profile checks. - Use rectangular, trapezoidal, V-shape, half-circular, Manual XS and saved custom XS profiles. - Support optional local Manning's n values and bank extension above the defined profile. - Plot profile, WSL, wetted area, wetted perimeter, crest and freeboard checks. - Copy or export visible profile/plot values for quick QA and reporting. This tool is part of QFAT (QGIS Flood Analysis Toolkit) — a set of focused QGIS utilities designed to support flood modelling workflows (e.g., TUFLOW, HEC-RAS), hydraulic QA, and rapid engineering checks.
