Минимальные свидетельства наличия углерода вечной мерзлоты в реке Колыме в Сибири
Новое исследование показало, что арктические реки в настоящее время переносят ограниченное количество растворенного органического углерода из вечной мерзлоты, что имеет значение для понимания изменения углеродного цикла в регионе и его потенциальной возможности ускорить изменение климата.
Seismometers Listening at Rivers to Measure Sediment Transport
Bedload sediment, transported throughout an alpine catchment by a flood, was remotely tracked in detail by analyzing the ground vibrations recorded by a network of 24 seismic sensors.
Diez ríos que enfrentan contaminación, desarrollo y cambio climático–Y las políticas que pueden ayudar
Reporte anual destaca 10 vías fluviales que han llegado a encrucijadas en las cuales el apoyo del público puede determinar si reciben protección.
A Holistic Approach to Hydropower Data
A new online platform offers comprehensive data and tools about U.S. hydropower assets, enabling data-driven decisionmaking at the energy–water nexus.
Current Agriculture Adds More Phosphorus to Streams Than to Lakes
Improved agricultural nutrient management could improve stream water quality by reducing phosphorus levels, but rising temperatures and rainfall due to climate change might offset improvements.
Frozen Riverbanks May Erode Faster in a Warming Arctic
Frozen flume experiments reveal the sensitivity of permafrost riverbank erosion to water temperature, bank roughness, and pore-ice content.
Biogeochemical Insights from a Major Amazonian River
Underrepresented in global carbon budgets, tropical rivers like Brazil’s Tocantins are in need of study to establish their baseline characteristics in the face of increasing global change.
Mud Could Have Made Meandering Rivers Long Before Plants Arrived
New evidence from 1.2-billion-year-old rocks suggests that single, sinuous channels could have formed in muddy floodplain sediments without the stabilizing help of vegetation.
How Much Terrestrial Precipitation is Used by Vegetation?
Precipitation is partly used by vegetation and partly transformed into river flow. Quantifying the amount of water that is directly used by vegetation is essential to decipher climate change’s impact.
