Inferring the timing of abandonment of aggraded alluvial surfaces dated with cosmogenic nuclides [PDF]
Earth Surface Dynamics, 2019 Information about past climate, tectonics, and landscape evolution is often obtained by dating geomorphic surfaces comprising deposited or aggraded material, e.g. fluvial fill terraces, alluvial fans, volcanic flows, or glacial till.

Effect of debris-flow sediment grain-size distribution on fan morphology [PDF]
Earth Surface Dynamics, 2022 Knowledge of how debris flows result in the fan-shaped morphology around a channel outlet is crucial for mitigation of debris-flow-related disasters and investigation of previous sediment transport from the upper channel.

How do modeling choices and erosion zone locations impact the representation of connectivity and the dynamics of suspended sediments in a multi-source soil erosion model? [PDF]
Earth Surface Dynamics, 2021 Soil erosion and suspended sediment transport understanding is an important issue in terms of soil and water resources management in the critical zone.

Evidence of, and a proposed explanation for, bimodal transport states in alluvial rivers [PDF]
Earth Surface Dynamics, 2018 Gravel-bedded rivers organize their bank-full channel geometry and grain size such that shear stress is close to the threshold of motion. Sand-bedded rivers, on the other hand, typically maintain bank-full fluid stresses far in excess of threshold, a ...

Identification of stable areas in unreferenced laser scans for automated geomorphometric monitoring [PDF]
Earth Surface Dynamics, 2018 Current research questions in the field of geomorphology focus on the impact of climate change on several processes subsequently causing natural hazards. Geodetic deformation measurements are a suitable tool to document such geomorphic mechanisms, e.g.

Long-profile evolution of transport-limited gravel-bed rivers [PDF]
Earth Surface Dynamics, 2019 Alluvial and transport-limited bedrock rivers constitute the majority of fluvial systems on Earth. Their long profiles hold clues to their present state and past evolution.

On the potential for regolith control of fluvial terrace formation in semi-arid escarpments [PDF]
Earth Surface Dynamics, 2016 Cut–fill terraces occur throughout the western Andes, where they have been associated with pluvial episodes on the Altiplano. The mechanism relating increased rainfall to sedimentation is, however, not well understood. Here, we apply a hillslope sediment

Seismic signature of turbulence during the 2017 Oroville Dam spillway erosion crisis [PDF]
Earth Surface Dynamics, 2018 Knowing the location of large-scale turbulent eddies during catastrophic flooding events improves predictions of erosive scour. The erosion damage to the Oroville Dam flood control spillway in early 2017 is an example of the erosive power of turbulent

Potential Volcanic Origin of the 2023 Short-period Tsunami in the Izu Islands, Japan
Seismica, 2023 On October 8, 2023, at 21:40 UTC (6:40 on October 9 local time), a tsunami warning was issued for the Izu Islands and southwest Japan. This tsunami was initially considered to be associated with the Mw 4.7 earthquake at 20:25 UTC (5:25 JST). However, we
