Intercomparison of a Regional Climate Model Ensemble for Selected European Catchments

open access: yesInternational Journal of Climatology, EarlyView.
This study analyzes a regional climate model ensemble for water cycle and water resource research with two models. Results show that ICON generally outperforms TSMP1 simulations, mainly with 2‐m temperature and precipitation. These findings serve as a baseline evaluation that shows how key structural differences influence the model skill.

Wheat Sowing Practices in No‐Tillage Systems Modify the Microrelief and Hydrosedimentological Attributes: RPAS‐Based Photogrammetry

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT The microtopographic characteristics of terrain are modified by soil management and conservation practices, affecting water infiltration, storage, runoff generation, and sediment transport. However, assessing soil microtopography at representative spatial scales remains challenging and time‐consuming.

Climate‐Driven Mangrove Dieback and Recovery: A Case Study in Albert and Leichhardt Rivers, Australia

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Cycles of dieback and recovery drove mangrove forest dynamics at the Albert and Leichhardt Rivers (Gulf of Carpentaria, Queensland, Australia) over 36 years (1987–2023). Landward margins were the most affected by reduced tidal inundation when the alignment of low lunar declination suppressed tidal range and extreme El Niño phases lowered mean sea level.
