Particle transport mechanics and induced seismic noise in steep flume experiments with accelerometer‐embedded tracers

Abstract: Recent advances in fluvial seismology have provided solid observational and theoretical evidence that near‐river seismic ground motion may be used to monitor and quantify coarse sediment transport. However, inversions of sediment transport rates from seismic observations have not been fully tested against independent measurements, and thus have unknown but potentially large uncertainties. In the present study, we provide the first robust test of existing theory by conducting dedicated sediment transport experi… Show more

“…Hence, seismic monitoring shows potential for recording bedload flux, which has recently been demonstrated under laboratory and fields conditions (Gimbert et al, 2019;Schmandt et al, 2017). However, unlike signals derived from bedload impact sensors and similar to the soundscape of rivers recorded by in-stream hydrophones (Geay et al, 2017), seis-mic signals derive from a multitude of sources (e.g., Roth et al, 2017) and, therefore, the identification, extraction, and processing of signals to determine bedload flux is challenging.…”

“…New methods were therefore designed to measure bedload in rivers (Gray et al, 2010). Among the spectrum of developed techniques, bedload transport monitoring can be achieved with the use of vibration sensors on impacted objects (Mizuyama et al, 2010;Rickenmann et al, 2014); by the record of bedload self-generated noises using hydrophones Marineau et al, 2016) or with seismic observations (Barrière et al, 2015;Gimbert et al, 2018;Roth et al, 2016;Tsai et al, 2012). Bedload flux can also be estimated by using apparent bedload velocity measured with acoustic Doppler current profilers (ADCP) (Rennie et al, 2002(Rennie et al, , 2017.…”

“…Seismic monitoring is achieved with geophones or seismometers which record the seismic waves propagating in the soil layer (surface waves). Similarly, the power of bedload seismic noises has been related to bedload fluxes in laboratory experiments (Gimbert et al, 2018) and partially in field-experiments (Roth et al, 2016). Acoustic and seismic monitoring provide continuous proxies that are related to bedload fluxes but these proxies are also dependent on additional bedload parameters (i.e.…”
