Abstract: Measurement of river bed topography plays a key role for validating sedimentary processes in experimental hydraulics. In addition to contributing to a general understanding of these complex processes, river bed mapping can substantially aid in the design of particular projects. This paper gives a brief description of methods that are currently available for the purpose of river bed mapping in hydraulic modeling: wool threads, depth pointer gauges, digital photogrammetry, and projection Moire. Lastly, instrumentation used at HermannGrengg Laboratories is presented together with an example for its employment on a bridge scour test.
