Abstract Many models of river meander migration rely upon a simple formalism, whereby the eroding bank is cut back at rate that dictated by flow, and depositing then migrates passively in response, so as to maintain constant bankfull channel width. Here new model presented, which separate relations are developed for bank. It assumed consists layer fine‐grained sediment cohesive and/or densely riddled with roots, underlain purely noncohesive sand gravel. Following erosion layer, fails form...
Abstract. The European Alps stretch over a range of climate zones which affect the spatial distribution snow. Previous analyses station observations snow were confined to regional analyses. Here, we present an Alpine-wide analysis depth from six Alpine countries – Austria, France, Germany, Italy, Slovenia, and Switzerland including altogether more than 2000 stations 800 used for trend assessment. Using principal component k-means clustering, identified five main modes variability regions...
The advance of morphodynamics research into new areas has led to a proliferation forms sediment mass balance equation. Without general equation it is often difficult know what these problem‐specific versions leave out. To address this, we derive form the standard Exner for that includes effects tectonic uplift and subsidence, soil formation creep, compaction, chemical precipitation dissolution. complete equation, (17), allows independent evolution two critical interfaces: between bedrock or...
Snow stores a significant amount of water in mountain regions. The decrease storage the snowpack can have relevant impacts on supply for and lowland areas that rely snow melting. In this work, we modelled Water Equivalent (SWE) using daily depth (HS) data obtained from 19 historical HS measurement stations located southern European Alps (Italy). Then, analysed long-term (1930–2020) variability monthly Standardised SWE Index (SSWEI) its links with climate change large-scale atmospheric...
Abstract. Knickpoints are fascinating and common geomorphic features whose dynamics influence the development of landscapes source-to-sink systems – in particular upstream propagation erosion. Here, we study river profiles associated knickpoints experimentally a microflume filled with cohesive substrate made silica, water kaolinite. We focus on effect knickpoint varying distribution base-level fall (rate, increment, period) strength, i.e., kaolinite content. Such simple cases directly...
Abstract Snow represents a fundamental water resource for mountain and lowland areas. Changes in the frequency magnitude of snow droughts can significantly impact societies ecosystems that rely on snowmelt to satisfy their demands. Here we documented quantified drought affected Italian Alps during early 2020s. We used 15 long-term snow-depth series (period 1930–2023, elevation range: 864–2200 m a.s.l.) simulate equivalent (SWE), conjunction with climatic reanalysis data river discharge...
The review of recent bathymetric and geophysical data collected in the framework several research cartographic projects have allowed a detailed reconstruction morpho-structural setting (neo)tectonic evolution for both Alpine Apennine margins Ligurian Sea (Italy). widespread occurrence erosional processes sediment mass movements along steep continental slope within system submarine canyons reflect close correlation between active tectonics morpho-dynamic Margin. This relation is better...
The Claritas Fossae (CF) is an elongated system of scarps and depressions >900 km long, representing the western boundary Thaumasia Region to south Tharsis volcanic province. Although there general agreement on tectonic nature such major physiographic feature, processes that led its formation are still debated. This study aims better understand evolution CF by combining two methodologies: kinematic numerical modelling structural mapping. Through modelling, we reproduce present-day...
Small intraslope basins (ϳ 100 km 2 ), or ''minibasins,'' such as those found on the continental slope of Gulf Mexico, have been filled predominantly by turbidity currents.Each minibasin is result local subsidence and partially completely isolated from neighboring ridges formed compensational uplift.We undertook a series experiments to investigate relationship between flow dynamics currents entering stratal architecture their deposits.The were performed using continuous-feed surge-feed...
Lineaments on regional scale images represent controversial features in tectonic studies. Published models explain the presence of lineament domains most geodynamic environments as resulting from enhanced erosion along strikes normal to upper crustal extension. Despite their success many frameworks, these fail existing strike-slip corridors that separate blocks, including transform faults. The present paper investigates distribution such environments, and specifically presents results a...
We present the interpretation of 11 radio echo-sounding (RES) missions carried out over Vostok—Dome Concordia region during Italian Antarctic expeditions in period 1995–2001. The extension and density radar data surveyed area allowed to reconstruct a reliable subglacial morphology identify four relevant morphological structures namely: Aurora trench, ridge South Hills. These show evidence compatible with presence tectonic features. Morphological considerations indicate their development...
A semipermanent Global Positioning System (GPS) network of 30 vertices known as the Victoria Land Network for Deformation Control (VLNDEF) was set up in Austral summer 1998 northern (NVL), including Terra Nova Bay (TNB), Antarctica. The locations were selected according to Cenozoic fault framework, which is characterized by a system NW‐SE regional faults with right‐lateral, strike‐slip kinematics. TNB1 permanent GPS station within VLNDEF, and following its installation on bedrock monument...
We present the characterization of geohazard-related features Ligurian Sea with map its physiographic domains (1:250,000 scale) and five maps (1:100,000 morphological morpho-bathymetric elements. These were realized in framework MaGIC (Marine Geohazard along Italian Coasts) project, promoted by Civil Protection Department. The submarine geohazards continental margins, together mapping marine geological are critical for management coastal risks. Multibeam bathymetric data combined...
This study describes a peculiar, yet common type of fracture showing staircase trajectory, which forms in rocks with moderately weak planar anisotropies.The trajectory is given by alter nat ing segments oriented parallel to (LaP) or at an angle (ramp) respect the lamination/layering.The analyses has been accomplished on travertines, are continental microbial/hydrothermal deposits having typical poorly stratifi ed strongly laminated texture.In these rocks, porosity and permeability have high...

Abstract The South Polar Terrain (SPT) of Enceladus is a site with eruptions gas and water ice particle plumes, which indicate internal geodynamic activity. These are located along series tectonic structures, that is, the Tiger Stripe Fractures (TSF), composed regularly spaced, linear depressions. SPT surrounded by sinuous chains ridges troughs (the Marginal Zone). To unravel tectonics affect region its evolution, we performed specific structural mapping quantitative analyses brittle...
