A culvert is a stream crossing structure for water underneath roads and railroads. Within the transportation network they play an essential part when it comes to reducing damage caused by flood events. When a natural stream enters a culvert the cross sectional area of flow is always reduced creating hydraulic conditions not typical to normal stream flow conditions.
Undersized or (partially) blocked culverts can cause upstream flooding with associated environmental damage and infrastructure costs. The aim of the research is to optimise the culvert design process to accurately reflect hydraulic conditions generated by various culvert design options. Results will increase the understanding of how culvert design can be used to optimise performance and reduce the substantial construction and maintenance costs associated with culverts.
