Experimental Set Up
Once pre-testing was completed, the full experimental set up was determined. Below shows images of the experimental set up including the use of AS Nortek Vectrino (for flow speed data collection) and Wavelab 3 (data acquisition for force measurement).

Experimental Conditions Matrix
Currently in industry, an assumption of 10% turbulence intensity is used when analysing open channel flows. It has also been noted that at the Fall of Warness, in Orkney, that the Turbulence Intensities experienced at the water surface and seabed are 6% and 13% respectively. Therefore by using a variety of meshing parameters, a range of flows and associated turbulence intensities were obtained. These can be seen in the table below.
With these seven scenarios, it is expected that the aims and objectives will be attained successfully. As the project progresses, it is expected that more scenarios will be used which have increased turbulence intensity
