An inexpensive circuit design for the acoustic detection of oscillations in bedload transport in natural streams |
|
| Authors: | M G Anderson |
| Abstract: | A circuit design is reported which is demonstrated to be capable of receiving and recording the underwater sound of inter-particle collisions on natural stream beds during the process of bedload transport. Field trials were undertaken in a natural stream with sand-sized bedload particles. The results obtained, for a constant stream stage, give support to the idea of the occurrence of short period oscillations in the rate of bedload transport. |
