Abstract. Runoff and flash flood generation are very sensitive to rainfall's spatial temporal variability. The increasing use of radar satellite data in hydrological applications, due the sparse distribution rain gauges over most catchments worldwide, requires furthering our knowledge uncertainties these data. In 2011, a new super-dense network containing 14 stations, each with two side-by-side gauges, was installed within 4 km2 study area near Kibbutz Galed northern Israel. This established...
Abstract. The CryoGrid community model is a flexible toolbox for simulating the ground thermal regime and ice–water balance permafrost glaciers, extending well-established suite of models (CryoGrid 1, 2, 3). can accommodate wide variety application scenarios, which achieved by fully modular structures through object-oriented programming. Different components, characterized their process representations parameterizations, are realized as classes (i.e., objects) in CryoGrid. Standardized...

Abstract. Permafrost warming significantly affects the stability of rockwalls in high altitude regions. Subsurface monitoring permafrost is essential to assess resulting potential geohazards. This study investigates dynamics at Aiguille du Midi (3842 m a.s.l., French Alps) using an Automated-Electrical Resistivity Tomography (A-ERT) approach, conducted over a period four years (2020–2023). A total three geophysical profiles have been installed on sides Midi. An autonomous acquisition system...
Abstract Although hillslope evolution has been subject to much investigation for more than a century, the effect of climate on morphology soil‐mantled hillslopes remains poorly constrained. In this study, we perform numerical simulations volcanic cinder cones in Golan Heights (eastern Mediterranean) estimate soil transport efficiency across significant north–south gradient mean annual precipitation (1100 500 mm). We use initial cone (constrained by stratigraphy), modern form (surveyed with...
Abstract Carbonate hillslopes are often soil mantled and display a classic convex morphology. In this study we examine controls on carbonate hillslope denudation morphology using modified regolith mass balance equation to account for chemical weathering dust input—two fluxes that commonly neglected in settings with silicate-dominated bedrock. We utilize seven sites the Eastern Mediterranean across significant gradient mean annual rainfall deposition flux. Combining cosmogenic 36Cl-derived...
Abstract. Water takes part in most physical processes that shape mountainous periglacial landscapes and initiation of mass-wasting processes. An observed increase rockfall activity high mountain regions was previously linked to permafrost degradation, water infiltrates into rock fractures is one the likely drivers related thawing destabilization. However, there very little knowledge quantity timing availability for infiltration steep slopes. This gap originates from complex meteorological,...
The enhanced rockfall frequency (V > 100 m3) first noticed in the European Alps, has motivated investigations on high mountain rock walls and wall permafrost since 2000s. Mont-Blanc massif (MBM) become a pilot study area thanks to wealth of data knowledge dynamics acquired through successive research projects. Statistical analysis distribution (> 1300 events inventoried between 2007 2021) shows that they are related increasing atmospheric temperature, opening promising perspective for...

An observed increase rockfall activity several regions was previously linked to permafrost degradation high mountains, water infiltrates into rock fractures is one likely drivers these processes. However, there very little knowledge on quantity timing availability for infiltration steep slopes. This gap originates from complex meteorological, hydrological...
Permafrost-affected rockwalls are highly sensitive to rapid climate change, sometimes leading rock slope failures threatening human lives and activities. Many studies have demonstrated a link between permafrost degradation rockwall instability, but there is still need document destabilization events improve the understanding of triggering mechanisms ultimately develop relevant approaches for hazard assessment.   Our study investigates little rock-avalanche (c. 229,000 m3) that...

Abstract. Hydrological models for runoff estimations and flash-flood predictions are very sensitive to rainfall's spatial temporal variability. The increasing use of radar satellite data in hydrological applications, due the sparse distribution rain gauges over most catchments worldwide, requires improving our knowledge uncertainties these data. In 2011, a new super-dense network gauges, containing 27 covering an area about 4 km2, was installed near Kibbutz Galed northern Israel. This...
Cracking is a primary rock-weathering mechanism in arid environments, where dry conditions typically limit the efficacy of water-driven weathering processes. Here, we present results from field-based experiment hyper-arid and frigid Antarctic Dry Valleys (ADV) that documented recurring periods transient accumulation liquid water along rock cracks during otherwise conditions. This moisture was likely sourced deliquescence hygroscopic salts sub-saturated humidity Analysis meteorological data...
L’augmentation de la fréquence des écroulements rocheux (V > 100 m3), d’abord observée dans les Alpes européennes depuis années 2000, a impulsé études sur parois haute altitude et le permafrost paroi. Le massif du Mont-Blanc (MMB) est progressivement devenu un terrain d’étude pilote grâce aux nombreuses données connaissances acquises au travers divers projets recherche. L’analyse statistique distribution (> 1300 événements recensés entre 2007 2021) met en évidence leur lien avec ainsi...
