I built a free, browser-based hydraulic simulation tool for water engineers — no software to install.

🌊 WNTR GIS Tool — live on Hugging Face Spaces
https://lnkd.in/g3_fPbKN

Here's exactly how it works:

𝟭. Upload your data
Drop in a shapefile ZIP (junctions, pipes, pumps, valves, reservoirs, tanks, customer points) or an EPANET .inp file directly. No Hugging Face account needed — just open the link and go.

𝟮. Configure your simulation
Choose static or Extended Period Simulation (EPS up to 7 days), set demand per junction or distribute from customer-point shapefiles, and optionally apply a 24-hour diurnal demand pattern.

𝟯. Run
WNTR's pure-Python hydraulic solver runs on the server — no EPANET binary, no local compute. Takes seconds on typical networks.

𝟰. Inspect results
→ Interactive map: pressure-coded nodes, diameter-scaled pipes, customer points coloured by junction pressure
→ Ontario MECP compliance gauge (275 kPa / 140 kPa thresholds)
→ EPS time-series pressure charts across any selected junctions
→ Pipe criticality analysis — ranks which pipes cause the most failures when closed
→ Shapefile + CSV export ready for QGIS or ArcGIS

𝟱. Ask AI about your results
Open the AI Analysis tab, paste your own API key (Claude, GPT, Gemini, Groq, or Mistral), and ask questions directly about your network. The simulation results are sent automatically as context — no copy-pasting.

Groq has a free tier, so users who don't want to pay anything can still run AI analysis at zero cost.

🔑 No installation. Completely free to simulate.
