Modification of the hydrological cycle and, subsequently, of other global cycles is expected in Arctic watersheds owing to global change. Future climate scenarios imply widespread permafrost degradation caused by an increase in air temperature, and the expected effect on permafrost hydrology is immense. This study aims at analyzing, and quantifying the daily water transfer in the largest Arctic...

Original scientific paper Hydrological simulation in meteorological ungauged areas has always been a difficult problem for the study on atmospheric and hydrological coupling; meanwhile, it is also one of the important factors that restrict model development and basin water resource knowledge. To analyze the mechanism of atmospheric and hydrological coupling, this study quantitatively evaluated ...

[1] This paper aims to provide a prototype research of how MODIS observations can help to better understand surface and atmosphere conditions over the Tibetan Plateau. Snow melt and summer rainfall over the Tibetan Plateau provide the origin for most of the rivers in South Asia. Therefore, adequately monitoring as many components of the hydrological cycle as possible over the Tibetan Plateau ca...

The global hydrological cycle is characterized by complex interdependencies and self-regulating feedbacks that keep water in an ever-evolving state of flux at local, regional, levels. Increasingly, the scale human impacts Anthropocene altering dynamics this cycle, which presents additional challenges for governance. “Earth system law” provides important approach addressing gaps governance arise...

The Tarim basin is a unique ecosystem. The water from the Tarim River supports both wildlife and humans. To analyze the effects of both land use and climate changes on groundwater, a research site was established at Yingibazar, which is a river oasis along the middle section of the Tarim River. A hydrological survey was performed to assess the general water cycle in this area with special empha...

The observed sea surface temperature in the Southern Ocean shows a substantial warming trend for the second half of the 20th century. Associated with the warming, there has been an enhanced atmospheric hydrological cycle in the Southern Ocean that results in an increase of the Antarctic sea ice for the past three decades through the reduced upward ocean heat transport and increased snowfall. Th...

There is a major concern on current restoration and management programmes being applied over Doñana Ramsar Site. Historical inundation regime has been largely changed according to human transformations. On site measurements along short and recent periods have provided scant local information on inundation variability. Historical inundation patterns on a spatial basis are necessary to understand...

It is well documented that human modification of the hydrological cycle has profoundly affected the flow of liquid water across the Earth's land surface. Alteration of water vapor flows through land-use changes has received comparatively less attention, despite compelling evidence that such alteration can influence the functioning of the Earth System. We show that deforestation is as large a dr...
