IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Study of different kind of tidal bores in laboratory
the object of many investigations and some aspects remain always unknown. In this paper, we generate such type of flow in a laboratory to investigate the influence of different parameters as the water depth, the upstream velocity and initial conditions of boundary layer. Different kinds of moving bores have been generated for one Froude number Fr=1.29 and three initial boundary layer conditions. The water depth evolution does not seem to be affected by the boundary-layer conditions while the internal flow is significantly altered during the passage of the whelps depending on these conditions. The time evolution of the velocity fields is shown inside the water column and quantities like Reynolds stresses, the turbulent kinetic energy, and acceleration and pressure fields are evaluated from the TR-PIV and spatio-temporal filters of the data. The results show the influence of the different conditions and suggest that different kind of tidal bores could be measured on the field.Form Required :
