## What is Culvert Studio?

Culvert Studio is a free, educational showcase of our engineering-software capabilities — built to demonstrate the kind of tools we can create for professionals in civil engineering, drainage, stormwater, and hydrology.

WHAT YOU CAN EXPLORE
- Rational Method + Manning's equation for peak-flow and culvert sizing
- Recommended culvert size, design flow, and velocity — in seconds
- Inlet/outlet control analysis with performance curves and headwater checks
- Multi-barrel, orifice, weir, and tidal-tailwater analysis for coastal culverts

OFFLINE CANADIAN IDF DATA
- 565 IDF weather stations across all 13 provinces and territories
- 28,900+ data points — rainfall intensity/duration/frequency curves, fully offline
- No internet required at the job site

VISUALIZE & VERIFY
- Interactive 2D/3D culvert profile with design-flow animation
- Velocity, HW/D, and compliance checks against provincial drainage manuals (ON, AB, BC, SK, MB, QC)
- Save projects and calculations; export reports as PDF or GeoJSON/KML

MORE THAN A CALCULATOR
- Bridge hydraulics, fish passage, detention, channel, and drainage-network tools
- Environmental data integration: tidal (CHS IWLS), snow (ECCC), hydrometric (WSC)
- Bilingual English / Français

AN EDUCATIONAL DEMONSTRATION
Culvert Studio is provided as an educational, experimental showcase of what we can build — not as a substitute for professional design software. Always have results verified by a qualified engineer.

Built for Canadian conditions. Works offline.

If you work in civil engineering, drainage, stormwater, or hydrology, we'd love to hear from you. Request a feature, suggest an improvement, or contact us about a custom solution.
