Laboratory Measurements of Unsteady Flows through Culverts
Culverts are probably the most common hydraulic structure in rivers and open channels. Unsteady flow in culverts is of a complex nature due to multiple possible flow types occurring due to changes in the flow rate or the head or tail water levels. In fact, some culvert flow types are unstable and may exist only in a transitional state. Therefore, numerical models for open-channels with culverts should have the ability to predict culvert flow types accurately. However, laboratory or field data for unsteady flows through culverts is virtually nonexistent. Therefore, there is a need for such data. The research effort described in this paper presents unsteady flow laboratory measurements for flows through culverts. Real time data for discharge and water levels at several locations upstream and downstream of a culvert structure are collected. This data can be used to not only calibrate and validate numerical models, but also to improve our understanding of culverts flows and the transition from one flow type to another.
