VIDEOS OF 2D H&H MODELS

Bridge & Stream Engineering is proud to offer two-dimensional (2D) modeling capabilities for drainage study projects.  Below are examples of 2D models utilized on recent projects.

The video above shows a meandering river system and how large flows escape the main river channel. This 2D hydraulic model allowed BSE to quantify flows through each railroad bridge individually and how changes to one bridge affects the other. 

The video above shows a storm hydrograph routed through several culverts. This 2D hydrology model allowed BSE to quantify the reduction effects of storage and split flow on the design flow rates through the railroad culvert.

The video above shows a complex hydraulic situation with multiple inflows, several culverts and embankments that create commingling flows, split flows, and overtopping. This 2D hydraulic model allowed BSE to quantify flows through specific drainage structures using a system-wide analysis.

The video above was created as part of a desktop drainage study using LiDAR data. This 2D hydraulic model allowed BSE to analyze the ponding and storage effects of the railroad embankment without requiring a site visit.

The video above was created using photogrammetry data obtained from a drone flight. This 2D hydraulic model allowed BSE to analyze the split flow effect of railroad bridges, even in an area of the country without publicly-available LiDAR data.
