Laboratory flume experiments with the Swiss plate geophone bed load monitoring system: 2. Application to field sites with direct bed load samples

Abstract: The Swiss plate geophone is a bed load surrogate monitoring system that had been calibrated in several gravel bed streams through field calibration measurements. Field calibration measurements are generally expensive and time consuming, therefore we investigated the possibility to replace it by a flume‐based calibration approach. We applied impulse‐diameter relations for the Swiss plate geophone obtained from systematic flume experiments to field calibration measurements in four different gravel bed streams. T… Show more

“…Due to the inclusion of four additional calibration measurements obtained in 2012 and 2013, the correlation coefficient for the Ruetz is lower than in an earlier analysis that used only 17 measurements from the period 2008 to 2011 . This level of correlation is similar to calibration measurements obtained for the Navisence stream in Switzerland (Wyss et al, 2016c) for which most measured bedload masses were smaller than 20 kg; for the Ruetz, 15 out of 21 calibration measurements also have bedload masses smaller than 20 kg. Using the k tot coefficient from Eq.…”

“…During the largest event in the study ( τ peak = 304 Pa), the activity of these tracers increases by an order of magnitude to 18%. Tracer particles more comparable to the median mobile grain size at the Erlenbach ( D tracer = 7.6 cm, D 50 = 7 cm from Wyss et al, ) exhibit a similar pattern. The active fraction of D 50 ‐size tracers increases threefold, from 15% to about 50% during the largest event.…”

“…To estimate the proportion of particles in the range 2 mm < D < 10 mm, also the particles with D < 10 mm caught in the sampler were used in the analysis. This provides a lower estimate of the transported particles with sizes in this range which are not detected by the geophone impulse counts (Wyss et al, ). After initial filling of the sample bag, the mesh is clogged by sediment and thus a substantial part of particles smaller than 10 mm and even smaller than 2 mm were also caught.…”
