The Colorado River in the Grand Canyon — thalweg, bend radius and wavelength extracted from the 3D surface in your browser. This is what the Atlas computes.(u = model units; width tick is illustrative)
Flagship tool · in development
River Morphology Atlas
The first web app to predict and classify river morphology with several state-of-the-art methods at once — and to tell you honestly when they disagree.
Multi-method by design
Runs several state-of-the-art classifiers side by side — planform predictors, hydraulic geometry, and morphological quality indices — instead of trusting a single equation.
Two input modes
Enter hydraulic characteristics manually (discharge, slope, D50, bank vegetation…), or upload HEC-RAS 1D/2D output for automatic reach segmentation and per-reach reports.
Validity screening
Every method carries its applicability limits. Results outside a method’s calibrated range are flagged — not silently reported.
Agreement dashboard
When methods disagree, you see it. Convergence and divergence across methods is a first-class output, not a footnote.
Provenance for every number
Each result links back to its source equation and original publication. No black boxes — every value has a birth certificate.
Privacy-first processing
HEC-RAS files are parsed entirely in your browser. Your model results never leave your machine.
How it works
River in, verdict out
Feed it a river
Manual hydraulic parameters, or a HEC-RAS results file — reaches are segmented automatically.
Engines run in parallel
Planform, hydraulic-geometry and quality-index methods evaluate every reach independently.
Read the verdict
A per-reach morphological report with validity flags, method agreement, and full source citations.
Status: in active development
The research phase is complete — methods selected, equations verified against their original publications, and the architecture designed. The atlas will launch here on vindaflow.com. Interested in early access, collaboration, or sponsoring a feature?
