Electronic Theses and Dissertations
The movement of coarse gravel in rivers in streams is important for many applications including wildlife habitation, river morphology, infrastructure maintenance and marine navigation. Physical sampling remains the most accurate method of determining coarse bedload transport but it can be expensive, dangerous and flow intrusive. Surrogate methods of monitoring bedload transport is an active area of research worldwide. One such method is the use of passive acoustics to record the sound generated when gravel particles in motion impact each other or the particles on the bed. This dissertation presents research and development that has been conducted on three key areas …
