Feature Roadmap

Save, load, rename, and delete analysis projects. Inline results preview, sortable table, and PDF download, no browser storage limits.

Real-time 3D rendering of culvert geometry, embankment, and water surface with hydraulic boundary conditions and velocity heatmap overlay.

FHWA-standard color-coded velocity heatmap on plan view with HEC-14 apron design geometry and outlet protection extents.

Q = CIA design flow estimation with live result display, return period selection, area-weighted C calculator, and one-click transfer to design inputs.

Printable engineering report with full inputs, results, design matrix, and design notes. Formatted for submission and review.

Compare all pipe sizes across multiple materials simultaneously. Expand any material to see HW, velocity, and Froude number. Optional material cost column for budget-aware selection.

Square edge and groove/socket end (headwall), projecting, mitered to slope, and 45° / 33.7° beveled ring inlets, each with FHWA Appendix A inlet-control coefficients.

Covered by 303 automated validation tests against FHWA HDS-5 published examples. A structured audit of the physics engine is ongoing, with deeper edge-case coverage in progress: flow regime transitions, skewed inlets, and boundary condition extremes.

Ongoing platform refinements driven by real use and feedback:

• Project version control
• PDF export refinement
• 3D Section View model upgrades
• Public-page readability and in-page navigation
• General UI and performance tweaks

Reinforced concrete box culvert design per FHWA HDS-5 with standard headwall, wingwall, and skewed inlet configurations.

Design and compare 2 to 4 parallel barrels, with side-by-side performance against a single barrel and shared design-matrix output.

Wingwall and tapered inlet configurations beyond the six inlet types already supported, matched to FHWA inlet geometry tables.

Pipe arches, elliptical pipes, and other non-circular sections with FHWA-standard shape coefficients.

Multi-sheet workbook with full input summary, design matrix, performance curves, and embedded charts, ready for project file submission.

Run all return periods (2, 5, 10, 25, 50, 100-year) in a single pass and generate a tabulated headwater summary across events.

Compute tailwater depth from the downstream channel section, slope, and Manning's n. Manual entry stays available when you have a measured TW elevation.

Outlet velocity output paired with FHWA HEC-14 riprap class recommendations, material erosion thresholds, apron length, and downstream channel protection notes.

Group the culverts on a road or site project under one record. Shared metadata (project name, engineer, design storm), per-station inputs, and a project-level summary that covers all crossings. Sized for corridors with 5 to 15 crossings.

Comprehensive third-party review by a licensed PE with a published, citable validation document.

GPS tagging, quick-check input form, and field report generator for on-site inspection and as-built verification.

Import DEM or LiDAR data to auto-extract channel geometry, embankment profile, and slope from terrain data.

Draw an embankment cross-section on screen. The platform converts your sketch into station/elevation data and runs the hydraulic analysis automatically, ideal for quick field checks.
