SRH-2D has the capability to model hydraulic structures including: bridges, culverts, gates, and weirs.
Culvert
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.
Specific guidelines include:
- The user must specify a file (path and name) where all HY-8 crossing definitions used in this boundary condition coverage are stored. This is accessed by right clicking on the coverage and selecting "HY-8 Options".
- The user must define the crossing before running SRH-2D. The crossing definition can be accessed in the boundary condition dialog after assigning the arcs to be a culvert.
- HY-8 computes flow both through the culvert and over the road/weir above the culvert. Attributes are specified in the crossing definition.
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.
