Open Channel Hydraulics for the Practical Engineer

Finally, an easy alternative to HEC-RAS. Channel Studio is software purposely designed to be an easy-to-use tool for performing day-to-day hydraulic analysis on open channel systems. Use Channel Studio to compute water surface profiles for any open channel including bridge structures, culvert crossings and inline weirs. Draw realistic river reaches directly on your map, add cross-sections and compute. Stunning graphical outputs are accompanied by easy-to-read tabulated reports and live technical support.

This is Not Your Grandfather’s Software

Even though it uses long established methodologies for open channel hydraulics, this software is brand new, inside and out. It’s not a data wrapper or a pretty user interface on top of HEC-RAS or other freeware-type software. Channel Studio is all-inclusive, purpose built for open channel modeling from the ground-up and needs no other software to run.
No importing. No exporting. No stress. A real breakthrough.

Draw Realistic River Reaches

Natural channels don’t flow in straight lines right? With Channel Studio, rivers flow the way their supposed to… meandering. Capture an image from Google or Bing, specify coordinate extents and draw river reaches directly on your map. Even over CAD DXF files! Of course you always draw on a blank (coordinate referenced) canvas. It’s your choice.

Easy to Learn & Use

Channel Studio has a modern-day, all-in-one user interface that puts everything in front of you… all the time. We eliminated those annoying dialog boxes and endless pull-down menus, replacing them with intuitive tabs and smart input grids. Compute and visualize results, graphic and numeric, while editing your inputs right there, in a smart grid-style editor. From now on, you can model open channels quickly and stress-free.

Intuitive, Graphical and Smart

Why waste time hand-calculating or manually inputting when you can do it with a mouse click? Easily add cross-sections to your model by simply rolling your mouse along the river reaches and clicking. Sections are automatically aligned, reach lengths computed, ineffective flow areas established and more!

Easy Geometric Data Entry

Just click on a section and add channel data the easy way. Save time using pre-defined section types or enter up to 250 points for user-defined sections.

Input options allow you to copy & paste station, elevation points from a spreadsheet, insert, delete and even reverse section data. Copy data from one section and paste into another. Adjust sections up or down. Even interpolate between any two unique sections!

Model Bridges

Add bridge structures anywhere on your model and Channel Studio will manage the details like low flow, pressure flow and overtopping flows. Specify high and low deck elevations as well as optional sloped or vertical abutments and piers. The software optionally computes and includes ineffective flow areas for the adjacent up and downstream channel sections. Also computes Contraction and Pier scour.

Model Culverts

We admit, we borrowed the technology from Channel Studio’s close cousin, Culvert Studio. And it allows you to do this:

Add single-barrel crossings to multi-barrel culverts with various shapes, inlet configurations, materials, slopes, sizes and flow regimes including supercritical flow with hydraulic jumps and overtopping flow… to any section on your river model. Nice!

Model Inline Weirs

Perfect for those occasions where you need to regulate upstream water surface profiles. Just add an inline weir structure to your model, set the crest elevation and you’re good to go. Channel studio automatically and dynamically determines the weir type (broad or sharp crested) based on the computed water depth and weir width, and applies the appropriate weir coefficient, Cw.

Time-tested Procedures & Features

When it has to be done right, Channel Studio has your back. Water surface profile calculation options include a variety of friction-loss methods. N-values can vary across sections via Left and Right Overbank stations. Graphically draw ineffective and blocked flow areas for more accurate results. Compute using up to three unique user-defined flow profiles, each with varying Qs and starting tailwater.

Accepted Calculation Methods

While Channel Studio is NOT some wrapper around HEC-RAS, it DOES employ the same methodologies for performing water surface profile calculations. These procedures are widely known and are used for open channel hydraulics calculations in Channel Studio. It handles subcritical and supercritical flow regimes with hydraulic jumps. It includes cross-section subdivision for conveyance calculations, composite Manning’s n across the channel section, velocity-weighing coefficients for Alpha, distance-weighted reach lengths and contraction and expansion losses.

Open Channel Modeling in 3D!

When it comes to water surface profiles, nothing explains it better than 3-dimensional perspectives. Channel Studio renders accurate 3D plots of any channel system with lightening speed. It even shows bridges, culverts, inline weirs, blocked obstructions and the water surface. Your clients will be impressed with the realistic colors and shading.

Plus, They’re Interactive

You’ll have a host of options on how you display and use these drawings. Click on any section or its number label and edit data right on the spot for immediate updating. Set the beginning and ending sections for higher detail.

Adjust the X and Y perspective parameters for different viewing angles. A simple move of your mouse wheel zooms in and out while a right-click saves the image to a file. These drawings are also included in your printed reports.

Import Projects from Raw Survey Data

Channel Studio makes simple work of going from field to finish… in one step. You can import your reaches and/or cross-sections from any .csv file containing Easting (X), Northing (Y), Elevation (Z) values and their associated Feature Codes.

Import/Export RAS GIS Files

Not only can you import data from RAS GIS files, you can easily share your project with other RAS GIS-supported CAD software for post-processing or GIS-based flood plain delineation.

Integrate With CAD

While you can import any dxf or image-based background map, you can also export. Channel Studio provides a georeferenced map of your flood plain for which you can export as an overlay back into your base cad drawings for flood plain delineation and other processing.

Bridge Scour

Bridge Scour Profile

Evaluates Bridge Scour Instantly

Channel Studio has the added ability to perform scour analysis through any bridge structure. It uses methods described in Hydrologic Engineering Circular 18 (HEC-18). All that is needed are two inputs; bed material, D50 and a selection of your pier shape if piers are present. Once input, Channel Studio automatically includes the scour calculations with the water surface profiles.

Contraction Scour

Channel Studio computes bridge contraction scour based on your median size bed material (D50). It employs both Live-bed and Clear-water equations during its evaluation.

Pier Scour

Pier Scour can be evaluated for each individual pier. Just indicate the pier nose shape (Rounded, Square or Sharp-triangular) and Channel Studio takes care of the rest.

It’s Time to Get Your Water Surface Profiles Dressed

Your expert engineering deserves an expert reward. Treat yourself to exceptional looking print-outs including plans, cross-sections, water surface profiles and tabulated reports.

Numerical reports can also be exported as text or comma delimited files for importing into spreadsheets for further customizing.

Each are designed to command authority while being easily understood by your peers and your reviewers.

Expert Technical Support

What’s worse than being stuck on a channel modeling project that’s under a deadline and having no one to turn to but 1,500-pages of text? Nothing.
