An acoustic bedload sensor was designed and developed as a part of the program. Its operation is based on the fact that sand at rest must dilate before moving and remain dilated in motion. Thus, it is possible to obtain reflections from the surface of the moving sand as well as from the layer at rest due to the different acoustic properties of the stationary and dilated sand.
