High‐resolution LiDAR and stereo‐DEMs for debris flow analysis in the Western Ghats, India: Sediment volume computation and run‐out modeling

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
The 2020 Pettimudi debris flow in the Western Ghats of India killed 70 people. Our study using stereo‐DEM, UAV‐based LiDAR data, and field data estimated the sediment loss as 17 × 104 m3. Abstract Computation of sediment volume and accurate modeling of run‐out using high‐resolution digital elevation models (DEMs) are essential for assessing debris flow

Remobilisation of fine sediment from chalk stream gravel beds under flushing flows: A flume experiment

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Through progressive flume experiments, this study demonstrated that increased bed shear stresses corresponded with increased cohesive fine sediment (<62‐μm) remobilisation depths from a representative chalk stream gravel bed. This represents some of the first scientifically robust data, which can direct revised and targeted fine sediment management in ...

A framework for in‐stream jams formed by snow avalanche‐delivered large wood

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Large wood delivered by avalanches organizes into blanket or transport jam complexes.Jam complexes increase channel width and promote pool and bar formation. Avalanche frequency and magnitude, which are dependent on hillslope angle and roughness characteristics, controls jam complex type.

The dual role of fracturing and elevation on the development of the weathering profile in mafic landscapes of the Andean tropics

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Eighteen boreholes in Colombia's Tropical Andes reveal elevation‐controlled Critical Zone architecture. Four‐layer weathering profiles with thick saprolite (≤48 m) form at high elevations (>1,100 m) where dense fracturing enhances permeability. Low‐elevation boreholes lack saprolite despite high fracture density, demonstrating fracturing's dual role as
