Short summary
Short summary
The expected spacing of step-pool sequences has long been mired in debate, hampering stream restoration efforts. We define a continuum to evaluate the degree of regularity and randomness across step-pools from field observations, flume experiments, and numerical simulations and show that the full range is occupied without one formation mechanism dominating. Bounds related to channel hydraulics provide a way to track dynamic step spacing without assuming a mechanism.

Large earthquakes trigger widespread landslides that increase the amount of sediment delivered to rivers. We studied suspended sediment grain sizes in a major Himalayan river basin following the 2015 Gorkha Earthquake in Nepal. We found coarser suspended sediments near heavily affected areas during the first year after the earthquake, with the signal disappearing downstream. These findings improve our understanding of how far and for how long earthquakes influence river sediment transport.

Short summary
Debris flows often move as multiple surges, like pulses of muddy water. Scientists have struggled to predict their overall behavior. By analyzing global data, we discovered hidden statistical laws governing how surges evolve and organize. We used these rules to build a computer model that recreates real surge sequences and predicts their size and frequency. This work provides a powerful new tool for assessing debris-flow hazards and improving early warning systems.

Short summary
Alluvial rivers form networks, but many concepts we use to analyse their long-term evolution derive from models that treat them as single streams. We develop a model including tributary interactions and show that, while patterns of sediment output can be similar for network and single-segment models, complex signal propagation affects aggradation and incision within networks. We argue that understanding a specific catchment's evolution requires a model with its specific network structure.

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
Water level suddenly rises during flash floods in dry regions having a distinct impact on bedload – large sediment rolling and saltating on the riverbed. Using sensor-equipped pebbles and seismic monitoring in a field setting, we demonstrate that bedload activity is very high in both shallow and deep sudden flows. These findings can help improve bedload transport models, particularly when using seismic sensors, by providing new insights into bedload dynamics.

Channel belts comprise the area affected by a river due to lateral migration and floods. As a landform, they affect water resources and flood hazard, and they often host unique ecological communities. We develop a model describing the evolution of channel-belt area over time. The model connects the behaviour of the river to the evolution of the channel belt over a timescale of centuries. A comparison to selected data from experiments and real river systems verifies the random walk approach.

The transport of plant debris in rivers is an important part of the global carbon cycle and influences atmospheric carbon levels through time. We sampled plant debris at the bed of a lowland river and determined the sources as it is transported hundreds of kilometers. Plant debris can persist at the riverbed, but mechanical breakdown reduces its amount, and it is only a small fraction compared to the suspended load. This plant debris and transport patterns need further investigation globally.

Fluvial valleys are ubiquitous landforms, and understanding their formation and evolution affects a wide range of disciplines from archaeology and geology to fish biology. Here, we develop a model to predict the width of fluvial valleys for a wide range of geographic conditions. In the model, fluvial valley width is controlled by the two competing factors of lateral channel mobility and uplift. The model complies with available data and yields a broad range of quantitative predictions.

The shape of drainage basins and rivers holds significant implications for landscape evolution processes and dynamics. We used a global 90 m resolution topography to obtain ~0.7 million drainage basins with sizes over 50 km2. Our dataset contains the spatial distribution of drainage systems and their morphological parameters, supporting fields such as geomorphology, climatology, biology, ecology, hydrology, and natural hazards.

Observations of the interaction between extreme physical erosion and chemical weathering dynamics are limited. We presented major elements of stream water in the badland catchment at 3 h intervals during a 3 d typhoon. The excess sodium in the evaporite deposits causes material dispersion through deflocculation, which enhances the suspended sediment flux. Moreover, we observed a shift from predominantly evaporite weathering at peak precipitation to silicate weathering at peak discharge.

Short summary
The impact of sediment grains on the riverbed is a key driver of bedrock erosion yet is rarely included in studies of landscape evolution. We propose an equation to address this issue by considering the distinction between grain lift and grain impact. We solved and analysed these equations for simple cases, such as the downstream evolution of a riverbed, and implemented them in a numerical code that simulated the retreat of a knickpoint.

Short summary
During glacial times in Switzerland, glaciers of the Alps excavated valleys in low-lying regions that were later filled with sediment or water. How glaciers eroded these valleys is not well understood because erosion occurred near ice margins where ice moved slowly and was present for short times. Erosion is linked to the speed of ice and to water flowing under it. Here we present a model that estimates the location of water channels beneath the ice and links these locations to zones of erosion.

The overall objective of the CHENILLE project is to performed an in-situ experiment in the Underground Reaserch Laboratory of Tournemire (Southern France) consisting of hydraulic and thermal stimulation of a fault zone. This experiment is monitored with extensive geophysical means (passive seismic, active seismic, distributed fiber optics for temperature measurements) in order to unravel the physical processes taking place during the stimulation for a better charactization of fault zones.

Short summary
Rivers can cut into rocks, and their strength modulates the river's erosion rates. Yet, which properties of the rock control its response to erosive action is poorly understood. Here, we describe parallel experiments to measure rock erosion rates under fluvial impact erosion and the rock's geotechnical properties such as fracture strength, elasticity, and density. Erosion rates vary over a factor of a million between different rock types. We use the data to improve current theory.
Rivers can cut into rocks, and their strength modulates the river's erosion rates. Yet, which...
