English | English Optical measuring methods applied the physical models of the BAW yield high quality and high quantity data. Using 2D particle tracking velocimetry, one camera records the velocity of the water surface. Using the 3D particle tracking velocimetry, three cameras are recording in three dimensions the water level and the surface velocity in the model at the same time. Three cameras also measure photogrammetrically the geometry and the changes of the river bed through the water during the ongoing experiment. Data are used in numerical models with which further dynamic analysis is performed. |
