    © 2015. Systematic snow disposal from street cleaning operations may create large anthropogenic snow/ice bodies. Such man-made cryospheric objects may be considered as complex geophysical interfaces between the atmosphere, landscape, soils and hydrosphere. Urban snow patches not only produce large amounts of meltwater (and therefore a risk of flooding), but also serve as multiphase chemical reactors due to highly polluted mixture of snow/ice with various materials and water inclusions. However, the exact roles of snow patches in the environment and the factors driving their temporal evolution remain unclear. They are nevertheless of major importance for informed decision making and sustainable disposal operations. Here we present the results of a 4-year monitoring program concerning two artificial snow patches near the town of Yuzhno-Sakhalinsk (Russia) and the results of numerical modeling inferring the main corresponding processes, i.e. melting and water discharges. The temperature-based index method proved adequate to assess the evolution of the two snow patches. Constant ablation factors of about 0.45-0.58 and 0.27-0.31cmw.e.d-1°C-1, respectively, were found to be appropriate for a first order approximation of snow patch melt dynamics. However, twice lower melt rates were found for one of the two closely located snow patches. This suggests that other factors, such as debris content, likely play a role. This difference in melting can be accounted for by modulating the ablation factor according to debris properties. In terms of peak daily water discharge, snow patch melting produces about 5-15cmw.e.perday, comparable to rain rates during regional typhoons. This study represents a starting point that should be followed by a more detailed monitoring program and the application of a more complex numerical model of snow disposal sites, to allow optimization of their maintenance. For example, marginal melting or the combined influence of debris and soils on surface runoff should be further investigated. Moreover, better constrained and formulated chemical processes will allow a more reliable estimate of the local environmental impact of regular snow disposal.

     Research paper (scientific journal) 
    © 2015 Author(s). Snowpack weak layers may fail due to excess stresses of various natures, caused by snowfall, skiers, explosions or strong ground motion due to earthquakes, and lead to snow avalanches. This research presents a numerical model describing the failure of "sandwich" snow samples subjected to shaking. The finite element model treats weak layers as interfaces with variable mechanical parameters. This approach is validated by reproducing cyclic loading snow fracture experiments. The model evaluation revealed that the Mohr-Coulomb failure criterion, governed by cohesion and friction angle, was adequate to describe the experiments. The model showed the complex, non-homogeneous stress evolution within the snow samples and especially the importance of tension on fracture initiation at the edges of the weak layer, caused by dynamic stresses due to shaking. Accordingly, a simplified analytical solution, ignoring the inhomogeneity of tangential and normal stresses along the failure plane, may incorrectly estimate the shear strength of the weak layers. The values for "best fit" cohesion and friction angle were ‰1.6 kPa and 22.5-60°. These may constitute valuable first approximations in mechanical models used for avalanche forecasting.

    © Author(s) 2014. CC Attribution 3.0 License. Natural sintering in ice is a fundamental process determining mechanical properties of various ice forms. According to the literature, limited data are available about the complex subjects of snow sintering and bond formation. Here, through cold laboratory mechanical tests with a new shear apparatus we demonstrate time-dependent effects of isothermal sintering on interface strengthening at various normal pressures. Measurements showed that interfacial strength evolved rapidly, conforming to a power law (mean exponent ≈ 0.21); higher pressure corresponded to higher initial strength and sintering rates. Our findings are consistent with observations on homogeneous snow, provide unique records essential for slope stability models and indicate the significant importance of normal load on data interpretation.

     Research paper (scientific journal) 
    The analysis of historical avalanche data is important when developing accurate hazard maps. The record of snow-avalanche disasters on Sakhalin and the Kuril Islands is incomplete, due to the historical division into periods of Japanese and Russian rule. Here we combine and analyze data from Japanese and Russian sources to reconstruct a continuous record of avalanche catastrophes in the region from 1910 to 2010. Despite the relatively small scale of the majority of catastrophic avalanches, with a total vertical drop <200 m, we document evidence that places the region among the most avalancheaffected areas in the world. In total, 756 fatalities and >238 injuries have occurred in 275 incidents over a 100 year period (two-thirds of those killed were Japanese). This death toll is higher than that in Canada, New Zealand or Iceland, or non-recreational fatalities in France. A wave of avalanche disasters (1930s-60s) following intense colonization of Sakhalin and the Kuril Islands is evident. Although this 'wave' could be considered a local issue of the past, many presently developing countries may face similar situations. The fatality rate has decreased over time, due to social factors, and differs from that of any other region, in its absence of deaths through recreational activities. Although in recent years the fatality rate is lower than that of Iceland or the USA, the per capita avalanche casualty rate on Sakhalin and the Kuril Islands remains among the highest in the world.
