Fluvio‐hydrological characteristics and diverse bedrock geology control the dynamic growth, truncation, and amalgamation of bedrock streambed and marine potholes

open access: yesRiver, Volume 4, Issue 1, Page 84-105, February 2025.
Abstract A total of 393 potholes (368 fluvial and 25 marine potholes) were studied at seven different sites in both the fluvial and marine environments. Diverse bedrock properties and large‐scale delivery of tools and grinders regulate the dynamic growth, truncation, and amalgamation of potholes. Therefore, the principal objectives of the study are (i)

Rock Glacier Kinematics in the Valles Calchaquíes Region, Northwestern Argentina, From Multi‐Temporal Aerial and Satellite Imagery (1968–2023)

open access: yesPermafrost and Periglacial Processes, Volume 36, Issue 1, Page 123-136, January/March 2025.
ABSTRACT In semiarid mountain ranges, rock glaciers constitute an important part of the periglacial environment. However, quantitative data on the state of rock glacier activity remain scarce. Here, we derive kinematic information on rock glaciers located in the Valles Calchaquíes region (24–25° S) in Argentina from optical feature tracking in ...
