Short summary
The Swiss plate geophone system has been installed and tested in more than 20 steep gravel-bed streams. It is an indirect bedload transport measuring system. We compare the performance of this system with three alternative surrogate measuring systems, using calibration measurements with direct bedload samples from three field sites and an outdoor flume facility. Three of the four systems resulted in robust calibration relations between signal impulse counts and transported bedload mass.

Bedload flux quantification remains challenging in river dynamics due to variable transport modes. We used a passive monitoring device to record the acoustic signals generated by the impacts of bedload particles with different transport modes, and established the relationship between the triggered signals and bedload characteristics. The findings of this study could improve our understanding of the monitoring system and bedload transport process, and contribute to bedload size classification.

Short summary
Short summary
Field measurements of the bedload flux with a high temporal resolution in several Swiss mountain streams were used to analyse the transport variability. The measurements were analysed for short-term transport events typically covering a duration of a few weeks and by considering multi-year annual transport totals. The findings show substantial variability both within and across sites, likely reflecting the influence of sediment availability, stream slope, streambed texture and flow history.

The paper presents an explicit stabilized two-phase material point method (MPM) based on the one-point two-phase MPM scheme. The novelty of the work lies in the employment of stabilized techniques, including the strain smoothing method and the multi-field variational principle. With its effective and easy-to-implement stabilized techniques, the proposed model offers an effective and reliable approach for simulating both static and dynamic processes in solid–fluid porous media.

This paper presents a novel model that predicts how gravel riverbeds may evolve in response to differences in the frequency and severity of flood events. We test our model using a 23-year-long record of river flow and gravel transport from the Swiss Prealps. We find that our model reliably captures yearly patterns in gravel transport in this setting. Our new model is a major advance towards better predictions of river erosion that account for the flood history of a gravel-bed river.

Short summary
Field measurements of the bedload flux with a high temporal resolution in a steep mountain stream were used to analyse the transport fluctuations as a function of the flow conditions. The disequilibrium ratio, a proxy for the solid particle concentration in the flow, was found to influence the sediment transport behaviour, and above-average disequilibrium conditions – associated with a larger sediment availability on the streambed – substantially affect subsequent transport conditions.

Various models have been used in science and practice to estimate how much large wood (LW) can be supplied to rivers. This contribution reviews the existing models proposed in the last 35 years and compares two of the most recent spatially explicit models by applying them to 40 catchments in Switzerland. Differences in modelling results are discussed, and results are compared to available observations coming from a unique database.

Monitoring sediment transport is relevant for flood safety and river restoration. However, the spatial and temporal variability of sediment transport processes makes their prediction challenging. We investigate the feasibility of a general calibration relationship between sediment transport rates and the impact signals recorded by metal plates installed in the channel bed. We present a new calibration method based on flume experiments and apply it to an extensive dataset of field measurements.

Short summary
Debris-flow prediction is often based on rainfall thresholds, but uncertainty assessments are rare. We established rainfall thresholds using two approaches and find that 25 debris flows are needed for uncertainties to converge in an Alpine basin and that the suitable method differs for regional compared to local thresholds. Finally, we demonstrate the potential of a statistical learning algorithm to improve threshold performance. These findings are helpful for early warning system development.

One of the most interesting problems in geomorphology concerns the conditions that mobilise sediments grains in rivers. Newly developed
smartpebbles allow for the measurement of those conditions directly if a suitable framework for analysis is followed. This paper connects such a framework with the physics used to described sediment motion and presents a series of laboratory and field smart-pebble deployments. Those quantify how grain shape affects the motion of coarse sediments in rivers.

Short summary
We designed a novel surrogate bedload monitoring system that integrates phased microphone arrays and an accelerometer for enhanced performance. By combining beamforming-based localization with amplitude calibration, we demonstrate a viable approach to enhance the reliability of bedload measurements. These findings address the key question of whether impact-based acoustic systems can be refined to provide more accurate particle size estimates and offer conceptual and methodological advances.
