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.
