Abstract:
... Shallow landslides (SLs) are rapid soil mass movements, typically occurring in the mountain areas, involving the most superficial soil layers up to 5 to 10 m in depth. Damages, and casualties due to shallow landslides are recorded globally, and in literature a variety of models to study landslides have been implemented hitherto. Often times, shallow landslides occur in the wake of snowfall events, ...

Abstract:
... the Jingou River basin (located in central Xinjiang, China). Estimating snowmelt runoff in alpine areas lacking monitoring stations is essential for water resource management. The newly released global precipitation measurement (GPM) data provide a high-precision precipitation input data source for snowmelt runoff simulations in such areas. However, the resolution (10 km × 10 km) is still insuffic ...

Climate change is disproportionately impacting mountain ecosystems, leading to large reductions in winter snow cover, earlier spring snowmelt and widespread shrub expansion into alpine grasslands. Yet, the combined effects of shrub expansion and changing snow conditions on abiotic and biotic soil properties remains poorly understood. We used complementary field experiments to show that reduced sno ...
