In Antarctica, understanding snow movement is crucial for assessing ice sheet mass balance and tackling logistical challenges related to human infrastructure. So far, extensive research has focused on snow-wind interactions on flat terrain, emphasizing the crucial roles of flow turbulence and snow properties. This work expands an existing Eulerian-Lagrangian model by incorporating buildings to simulate snowdrifts around complex structures, using advanced saltation physics. The German Antarctic research station Neumayer III is used as a test site. This development brings new levels of interaction between snow particles and larger structures, making the simulations more representative of real-world conditions. Specifically, numerical simulations were conducted to test the influence of six parameters on snowdrift formation, namely: wind force, snowbed cohesion, particle diameter, precipitation rate and building height and shape. Results show that the size of snowdrifts is mostly affected by wind force, preferential deposition and snowbed cohesion, while fine features of the building shape control their form. Nevertheless, significant uncertainties remain regarding the interaction of these parameters, highlighting the need for further research to improve modeling frameworks. This study demonstrates that our model is well-suited for engineering applications, guiding optimal designs for buildings and infrastructure in snow-affected environments.</p>","PeriodicalId":15887,"journal":{"name":"Journal of Geophysical Research: Earth Surface","volume":"130 3","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Formal classifications of meander bends have provided an important framework for basic research and practical applications in river engineering and restoration. However, the central role of expert interpretation in both mapping and classifying meander bends leaves persistent uncertainty for whether their shapes do form patterns or instead represent a continuum of forms. This study analyzes meander bend shapes derived in a companion paper about the Beatton River, Canada, to test whether meander bends show repeating shapes without the prior assumption that such patterns exist. Meander bends are compared using Fréchet distance, a curve similarity measure, and evaluated for common shapes using agglomerative hierarchical clustering. The case study indicates that normalizing meander bend coordinates by wavelength and amplitude yields clusters of meander bends with internally consistent shapes. Characteristic meander bends for each cluster are derived by averaging the normalized coordinates and rescaling by the mean amplitude and wavelength for the source meander bends.

However, few previous studies have integrated real-time hydrodynamic data with sedimentary deposits. In particular, the range of depositional conditions over which mud accumulates remains poorly constrained, and little is understood about how these deposits are preserved in the stratigraphic record. To address this knowledge gap, we examined co-located hydrodynamic instrument data and sedimentary deposits from the lower Waihou River, Aotearoa New Zealand. Results reveal that “dynamic mud” events, including fluid mud and rapidly deposited mud, dominate the spatial and temporal record, with few “static mud” events in which mud is deposited through gravitational settling. We suggest that dynamic mud conditions with the potential for deposition may occur throughout the tidal cycle, although cyclic tidal successions are never fully preserved. Many of the trends in sedimentation observed in studies of larger systems are not present in this small muddy river system, indicating the significance of climatic and river-flow characteristics on the sedimentary record.

Herein, numerical models were established to quantitatively investigate the kinematic process of rapid long-runout loess landslides via the finite–discrete element method (FDEM). These models were calibrated according to the <i>Dabuzi</i> rapid long-runout loess landslide deposit and laboratory tests. We conducted systematic numerical simulations to explore the mass transport and energy conversion of a rapid long-runout landslide, focusing on the influences of the sliding volume and the traveling path topography undulation depicted by the fractal dimension. The rapid evolution of the mass structure from continuous to discontinuous, the transition from a solid state to fluid-like state, and the mutual influence of mass transport and energy conversion were quantitatively characterized during the landslide kinematic process. With increasing topographic surface's fractal dimension, the maximum displacement, maximum velocity, and volume expansion ratio of the landslide exhibited linear decreasing trends, and the accumulation morphology changed. Variations in these parameters with the sliding volume were opposite to those of the fractal dimension case, except for the deposit volume expansion ratio. Particularly, the surface mass always displayed extreme long-runout motion displacements. The mass transport characteristics, like the transition from acceleration to deceleration, were driven by the mutual conversion of potential energy to kinetic energy and the dissipation of friction and fracturing.

To study the flow of surface friction-different granular mixtures, we conducted discrete element method simulations of dense granular flows with varying concentrations of a highly frictional and a less frictional particle type. Each mixture is characterized by three interparticle friction coefficients defined for contacts between similar and dissimilar particle species. We show that the mixture rheology can be modeled by combining the rheologies of single-phase flows having interparticle frictions equal to those that exist in the mixture, weighted according to particle contact probabilities. Furthermore, by applying the contact probabilities on a recently developed friction-dependent constitutive model, it is possible to predict the rheology and micro-structural parameters of a wide range of mixture scenarios and flow geometries requiring only the interparticle friction coefficients as inputs.

In this study, we have identified a significant underestimation of surface deformation over permafrost using Sentinel-1 InSAR, which is attributed to unwrapping errors in interferograms. Specifically, the inclusion of interferograms with longer temporal baselines in the SBAS network will cause unwrapping errors to occur more frequently and severely, leading to a more pronounced underestimation, exceeding 3 times in severe cases. To address this issue, we propose a novel correction strategy to mitigate unwrapping errors by correcting long-span interferograms with reliable short-span interferograms in the temporal domain. Here, 12-day interferograms are utilized as the reliable interferograms for the correction. The results show that the seasonal deformation amplitude over an ice-rich permafrost location on the Tibetan Plateau increases to approximately 110 mm after applying the correction, compared to the previous underestimation of only about 28 mm. The proposed correction method facilitates accurate retrieval and verification permafrost products from InSAR time series, such as the ground ice/water storage and thickness of the active layer. This in turn deepens our understanding of surface deformation in permafrost regions under a warming climate.
