2021/7/23
Identifying and understanding functional process domains (sensu Montgomery, 1999) in rivers is paramount for linking the physical habitat template to ecosystem structure and function.
Urban rivers are hotspots of riverine greenhouse gas (N2O, CH4, CO2) emissions in the mixed-landscape chaohu lake basin
Urban rivers greenhouse gas GHG Global warming
2021/7/27
Growing evidence shows that riverine networks surrounding urban landscapes may be hotspots of riverine greenhouse gas (GHG) emissions.

Sea level rise could make rivers more likely to jump course（图）
Sea level rise make rivers likely jump course
2020/8/21
Sea level rise is poised to shift the way rivers naturally chart their paths to the shoreline. The nature of that change will depend on both the rate of rise and the sediment load carried by the river...

On World Water Day and throughout the year, citizen scientists are providing valuable data on intermittently dry rivers in the Southwest United States.Trained citizen scientists are mapping three such...
Chemical weathering controls erosion rates in rivers
Chemical weathering controls erosion rates rivers
2016/4/25
Chemical weathering can control how susceptible bedrock in river beds is to erosion, according to new research. In addition to explaining how climate can influence landscape erosion rates, the r...
Humans concerned about climate change are working to find ways of capturing excess carbon dioxide (CO2) from the atmosphere and sequestering it in the Earth. But Nature has its own methods for the rem...
Distribution and supply mechanisms of high uranium concentration in the rivers of Okinawa Island, Japan
uranium river Okinawa Island guideline value supply mechanism
2017/4/10
Uranium concentrations in the rivers of Okinawa Island, Japan were determined in this study. Most rivers in the
southwestern area of the island showed high U concentrations, the highest of which was ...
Towards a publicly available, map-based regional software tool to estimate unregulated daily streamflow at ungauged rivers
publicly available map-based regional software tool estimate unregulated daily streamflow ungauged rivers
2014/12/17
Streamflow information is critical for addressing any number of hydrologic problems. Often, streamflow information is needed at locations that are ungauged and, therefore, have no observations on whic...
Process dynamics and controls in two partially-confined rivers of upper Brahmaputra plain
River dynamics erosion-deposition Brahmaputra plain Anthropogenic influence Gai and Simen river
2014/11/12
This work quantifies channel processes in two partially-confined rivers of Upper Brahmaputra plain, namely, Gai and Simen and explores their controls. To achieve the objectives this study utilises RS-...
