SRH-2D has the capability to model hydraulic structures including: bridges, culverts, gates, and weirs.

Culvert

A small culvert under a pedestrian walkway.

A structure that allows water to flow under a road, railroad, trail, or similar obstruction. SRH-2D can make use of culvert structures by coupling with the Federal Highway Administrations HY-8 culvert analysis application.

Gate

Gate structures can simulate both overflow and underflow gates.

Obstructions

Pressure Flow Bridge

A bridge can be represented as a pressure flow boundary condition in SMS.

Weir

A barrier across a river designed to alter its flow characteristics. In SMS, a weir can be represented as two arcs. One arc represents the upstream face of the weir structure and the other represents the downstream face of the weir.
