Description | Numerical simulations of turbulent flow over topographic roughness showed significant correlation between the turbulence structure and the water surface deformation. As a result of flow separation near the channel bed water surface waves occur and the wave frequency matches the frequency of the vortex shedding process of flow separation. As a secondary process, the small-scale turbulence of the flow deforms the water surface in more random patters. |
Exploitation Route | These results can be taken forward to design river monitoring equipment that would record and quantify surface waves, which can provide detailed information of the type of roughness that is found near the bed and can eventually lead to better flow monitoring. |
