Introduction Knowledge of snow parameters is important for climatology, meteorology, hydrology, flood prevention and hydropower industry. Liquid water in a snow pack shows a dominant effect on reflection, absorption and transmission of electromagnetic waves especially in microwave region. Liquid water in snow plays a major role in metamorphism, mechanics and hydrology of snow, and in soil engin...

Northern Hemisphere permafrost affected land areas contain about twice as much carbon as the global atmosphere. This vast carbon pool is vulnerable to accelerated losses through mobilization and decomposition under projected global warming. Satellite data records spanning the past 3 decades indicate widespread reductions (∼ 0.8– 1.3 days decade) in the mean annual snow cover extent and frozen-s...

This paper describes the use of a genetic algorithm to solve a hydrology design problem determining an optimal prescription of Best Management Practices in a flood-prone watershed. The result is an interactive tool for hydrology engineers that can be used to explore the effects of water retention and infiltration devices as an alternative to traditional storm sewers. The model has proved capabl...

[1] Vegetation, particularly its dynamics, is the often-ignored linchpin of the land-surface hydrology. This work emphasizes the coupled nature of vegetation-water-energy dynamics by considering linkages at timescales that vary from hourly to interannual. A series of two papers is presented. A dynamic ecohydrological model [tRIBS + VEGGIE] is described in this paper. It reproduces essential wat...

Soils lie at the interface between the atmosphere and the subsurface and are a key component that control ecosystem services, food production, and many other processes at the Earth's surface. There is a long-established convention for identifying and mapping soils by texture. These readily available, georeferenced soil maps and databases are used widely in environmental sciences. Here, we show ...

Permafrost plays a critical role in soil hydrology. Thus, the degradation of permafrost under warming climate conditions may affect the alpine grassland ecosystem on the Qinghai–Tibetan Plateau. Previous space-for-time studies using plot and basin scales have reached contradictory conclusions. In this study, we applied a process-based ecosystem model (DOS-TEM) with a state-of-the-art permafrost...

Heard Island contains a system of lava tube caves in a largely pristine condition which are the best developed bedrock caves known in Antarctic or Subantarctic latitudes. They require special management, because of significant and sometimes fragile attributes associated with cave geomorphology, geology, hydrology, atmospheres, soils, microbiology, flora, fauna, vertebrate palaeontology, archaeo...
