2d floodplain simulation

hydraulics

Hydraulic engineering is our specialty

From complex, 3-dimensional computational fluid dynamics (CFD) analyses to simple spreadsheet models, the majority of our projects require a level of hydraulic understanding.

cbec provides hydraulic services for a range of client needs

Whether we are analyzing floodplain inundation, scour at bridges, levee breaches, or particle mobility for everything from spawning gravels to bank protection, cbec has the right tool and staff member for the job.

We are leaders in the field of ecohydraulics and use our expertise in fish passage, habitat suitability prediction and computational fluid dynamics to inform the design of our environmental restoration and enhancement projects.

Ecohydraulics expertise

In some cases straightforward spreadsheet-based calculations will suffice, while, in others, sophisticated 2D or 3D hydrodynamic models are required to accurately answer the questions of concern.

Our staff is adept at all hydraulic models standardly used in riverine, estuarine and coastal environments (e.g., SRH-2D, MIKE models, TUFLOW, HEC-RAS, Delft3D, CE-QUAL-W2, etc.).

Beyond our multidisciplinary hydraulics skillset, our modeling capabilities also include tidal and fluvial sediment transport along with water quality modeling.

To develop, calibrate and test our models, we employ the latest surveying and monitoring technologies. We choose the right set of tools for each job, because we know that one size does not fit all.
