Standard box culvert flow

A culvert is a covered channel of relatively short length designed to pass water through an embankment (e.g. highway, railroad, dam). It is a hydraulic structure and it may carry flood waters, drainage flows, natural streams below earthfill and rockfill structures. From a hydraulic aspect, a dominant feature of a culvert is whether it runs full or not.
The design can vary from a simple geometry (i.e. box culvert) to a hydraulically-smooth shape (i.e. Minimum Energy Loss culvert) (Chanson 2004).
The video shows the flow in a box culvert (barrel width : 0.15 m). for a discharge less than the design flow rate. The model is in perspex . The video shows first the inflow, the barrel flow and later the outflow. The movie was taken in the Gordon McKay Hydraulics Laboratory of the University of Queensland.

This web site was launched by Prof. Michele Mossa of the Polytechnic University of Bari (Italy) with the initial support of Fondazione Caripuglia, Bari, Italy for the Research Project LIC-MON of 2003 and of the Project IMCA (Integrated Monitoring of Coastal Areas) financed by MIUR PON D.M. 593/00. Later, the initiative was supported with other Prof. Michele Mossa’s funds, most recently provided by the RITMARE Project.
