Study, Protect, Improve and Manage Water Dependent Eco Systems


Here at cbec we strive to produce sustainable designs. We’re different – we base our designs on physically based tools, combining form, process and innovation to meet ecological needs. Linking natural dynamics to ecosystems is key – we don’t use a standard template. Every project is new, challenging, and different. Check us out for more information.

What is eco engineering?

  • Eco engineering describes water resources engineering services that are concerned with developing and providing ecologically sensitive and environmentally sustainable solutions in the fields of hydrology, hydraulics, geomorphology and restoration and rehabilitation design.

  • cbec provides restoration and rehabilitation design in water-dependent ecosystems. We focus on “green development” to improve the way we develop urban infrastructure (including Low Impact Development). We combine hydrologic modeling and species prediction modeling to determine the potential ecological outcome of physical modifications to river channels and their adjacent floodplains. We design restoration and rehabilitation measures that will improve a degraded system using natural processes. We apply innovative design to sustainably maintain a healthy and diverse ecosystem without frequent intervention.

    Check out a recently completed project in Scotland! Talk about hydromodification, the video below shows the problem.

    This channel, a daylighted section of culvert, constructed around a new housing development, did not consider geomorphic form or process. We were called in to help solve the problem. As we were undertaking the design, two huge storms passed through (you may have heard about recent flooding in the UK – see link). Channel incision and headcuts of up to 2.5 m (that’s almost 9 feet in US customary!) formed. We based our design on what we saw, combined our geomorphic reconnaissance with hydrodynamic modeling and created a more sustainable solution, with greater ecosystem integrity. Hydraulic velocity and shear stress prediction combined with field verification, lead to a step pool and inset floodplain design. While maintenance will always be required to varying degrees, we think you will agree that this is a much more sustainable system!

    Shear stress output to inform design materials.

    Typical step-pool design.

    Hydrology, Hydraulics, Geomorphology, Design, and Field Services - these are the tools in our toolbox. See Projects for how we combine them all...

    Great minds think eco-like.
