Summary: The difficulties in directly monitoring traction processes - bedload and mass movements - have prompted research into surrogate monitoring technologies, among which acoustic methods (geophones, hydrophones, ADCPs) are presently most developed, as demonstrated in the 2007 International Bedload Surrogate Monitoring Workshop held in Minneapolis. Since then it is apparent that acoustic techniques have been further developed with increasing interesting results in seismics. Hence, the objectives of this workshop are to (1) present first-hand principles of acoustics and seismics, (2) discuss first-hand signal processing techniques relevant to surrogate monitoring of bedload and mass movements, (3) consider calibration issues, and (4) describe monitoring methods that have been recently developed or improved. Workshop topics will encompass surrogate monitoring of bedload transport (river and coastal), debris flows, snow avalanches, landslides and rock avalanches with acoustic and seismic devices. Invited and submitted presentations will concentrate on research using acoustic and some relevant seismic methods.

Workshop’s provisional timetable:
