Bridge Surveys

Our team is also renowned for its two-dimensional (2D) modeling capabilities for hydrology and hydraulics (H&H) drainage projects, as shown in the videos below.

Our 2D hydraulic modeling allows us to accurately predict how water splits and reconnects during storm events. By understanding exactly where and how water moves, we can strategically locate and properly size culverts — helping ensure reliable drainage, reduced flood risk, and long-term performance without overbuilding.

Using advanced unsteady flow modeling and detailed upstream topography, we analyze how water is temporarily stored and released during storm events. This deeper understanding often allows us to safely reduce the required design flow through a structure — which can mean a smaller, more cost-effective solution while still meeting performance and regulatory requirements.
