Culvert Studio

Culvert Design Software That's Easy to Use

Culvert Modeling & Design Software, Refreshingly Simple

Culvert Studio was designed to be a culvert modeler that is as easy to use as it is beautiful to look at. Everything is right in front of you, leaving you to be more productive, and not searching for dialog boxes. Use it once and you’ll be hooked. It’ll be the culvert design software you’ll prefer to use – and love – on every project.

What’s even better – it pays for itself the first time you use it.

Designed with User Experience in Mind

It’s no secret that you have options when purchasing culvert design software, but none compares to this.

Methodologies and standards for calculation procedures have long been established. But integrating methods with a simple user interface and outstanding graphics hasn’t been easy to come by… until now.

We worked hard at making this software easy to use. And that wasn’t easy. Its intelligent user interface is immediately evident when you first begin entering data into Culvert Studio. It watches over your input progress and displays helpful, context-sensitive diagrams along the way to keep you moving, stress-free.

It's Culvert Design Software... Modern-Day

If you’re tired of struggling with government-issued, outdated culvert design software there’s good news. Culvert Studio was built from the ground up using the latest software technology providing you with a rich user experience and rock-solid, time-tested results.

What You Can Do With Culvert Studio

Design and model single-barrel crossings or multi-barrel culverts with various shapes, inlet configurations, materials, slopes (positive or negative), sizes and flow regimes including supercritical flow with hydraulic jumps and over-topping flow. Employs FHWA HDS-5 methodology (same as HY8 but better) so you can design and model culverts with total confidence.

Better Quality Graphical Representations

The first thing you’ll notice is the graphical presentation of your culvert designs. Realistic water surface profiles match the exactness of the highly technical calculations. Just click on an output row to view corresponding profile, section and plan.

No Learning Curve

Culvert Studio was designed to be a culvert modeler that is as easy to use as it is beautiful to look at. Everything is right in front of you, leaving you to be more productive, and not searching for dialog boxes.

Culvert Design & Analysis Made Easier

Culvert Studio offers powerful ways to get your work done as efficiently as possible. Create up to 10 unique culverts  at once. Copy data from one, paste into another.  Model a variety of barrel shapes, inlet configurations and skew angles.

Varied Roadway Crossings & Embedded Barrels

Roadway crossings can be specified with a constant crest elevation and width or you can specify a varied profile. Include open-bottomed arch, box or embedded circular barrels for natural stream and fish passage preservation.

Computes Culvert Scour Geometry

Predict local scour at the outlet of your culverts. Using HEC-14 methodologies, Culvert Studio determines scour geometry for cohesive and cohesionless soils with minimal inputs.

Designs Culvert Riprap Aprons

Using HEC-14 methods, Culvert Studio determines the required dimensions of a riprap-based apron including length, width, depth, D50 rock size and FHWA Class. It even uses projectile motion equations to locate where the culvert outflow contacts the natural bed when there’s a free-falling drop height.

Design for Fish Passage at Roadway-Stream Crossings

Design embedded culverts with criteria that provide fish the ability to move both up and downstream while still complying with flood flow conveyance requirements.

Design & Retrofit Road Stream Crossings to Meet Fish Passage Requirements

A culvert becomes a barrier to fish passage when it demonstrates conditions exceeding fishes’ biological ability. Common obstructions to fish passage through culverts include excessive velocities, drops at culvert inlets or outlets, and scour.

Design Against Downstream Channel Degredation

Downstream channel degradation can cause a culvert to become perched, presenting a low flow barrier to fish passage. Culvert Studio has robust scour modeling abilities to help insure safe passage for fish when they're on the move.

Hydraulic Design for Fish Passage is Critical

Culvert velocities and depth at the inlet, barrel and outlet each play a critical role. Velocity at the inlet is the last barrier for a fish traversing a culvert. Insufficient depth will impair fishes’ ability to generate maximum thrust. These criteria and more can easily be met in Culvert Studio as it provides a detailed hydraulic profile including leap height, velocities, flow depths, and drop height.

World Class Reporting to Make You Look Good

In the end you’re rewarded with colorful graphics, detailed numerical output and reports that win reviewer approvals.

It’s everything you want, and nothing you don’t. It’s the way culvert modeling should be.

Buy Culvert Studio as stand-alone or bundled with the Suite

Built on Windows Presentation Foundation (WPF)

Built from the ground up using Microsoft’s dot-net WPF (Windows Presentation Foundation) it provides a rich and clean presentation while taking advantage of today’s modern hardware. It makes graphics rendering lightning fast. 

Culvert Studio employs Microsoft’s “Click-Once” technology for easy installations. Program updates occur with a single mouse click. 

System Requirements

Culvert Studio is a stand-alone software product. Any off-the-shelf PC running Microsoft Windows 10, 11 and beyond will run Culvert Studio. An internet connection is required for automatic program updates.
