The increased use of hydropower is currently driving the greatest surge in global dam construction since the mid-20th century, meaning that most major rivers on Earth are now dammed. Dams impede the flow of essential nutrients, including carbon, phosphorus, nitrogen and silicon, along river networks, leading to enhanced nutrient transformation and elimination. Increased nutrient retention via sedimentation or gaseous elimination in dammed reservoirs influences downstream terrestrial and coastal… 
Are nutrients retained by river damming?
Rivers are dammed for hydropower, flood control, navigation or water storage for human use. Globally, about half of the rivers are impacted by damming [1], withmajor consequences for biodiversity,
Global Dam‐Driven Changes to Riverine N:P:Si Ratios Delivered to the Coastal Ocean
River damming alters nutrient fluxes along the land‐ocean aquatic continuum as a result of biogeochemical processes in reservoirs. Both the changes in riverine nutrient fluxes and nutrient ratios
CO2 emissions from karst cascade hydropower reservoirs: mechanisms and reservoir effect
Carbon dioxide (CO2) emissions from aquatic surface to the atmosphere has been recognized as a significant factor contributing to the global carbon budget and environmental change. The influence of


Disrupting biogeochemical cycles - Consequences of damming
Abstract. Sustainable management of natural water resources should include environmentally sound dam construction and operation with respect to both upstream and downstream management. Because of
Global phosphorus retention by river damming
The global impact of dams on the riverine fluxes and speciation of the limiting nutrient phosphorus (P) is quantified using a mechanistic modeling approach that accounts for the in-reservoir biogeochemical transformations of P.
Effects of Damming on River Nitrogen Fluxes: A Global Analysis
Damming creates biogeochemical hotspots along rivers that modify the riverine flow of nutrients, including nitrogen (N). Here, we quantify the impact of dams on global riverine N fluxes using a
Global perturbation of organic carbon cycling by river damming
For the period 1970–2030, global carbon mineralization in reservoirs exceeds carbon fixation (P<R); the global P/R ratio, however, varies significantly, from 0.20 to 0.58 because of the changing age distribution of dams.

Biogeochemical hotspots: Role of small water bodies in landscape nutrient processing
Increased loading of nitrogen (N) and phosphorus (P) from agricultural and urban intensification has led to severe degradation of inland and coastal waters. Lakes, reservoirs, and wetlands (lentic
Homogenization of regional river dynamics by dams and global biodiversity implications
Long-term streamflow records are used on intermediate-sized rivers across the continental United States to show that dams have homogenized the flow regimes on third- through seventh-order rivers in 16 historically distinctive hydrologic regions over the course of the 20th century.
Do Hydroelectric Dams Mitigate Global Warming? The Case of Brazil's CuruÁ-una Dam
Hydroelectric dams in tropical forest areas emit greenhouse gases, as illustrated by the Curuá-Una Dam in the Amazonian portion of Brazil. Emissions include carbon dioxide from decay of the
Effect of Danube River dam on Black Sea biogeochemistry and ecosystem structure
Rivers contribute significantly to the pollution and eutrophication that have caused drastic changes to the ecosystem of the Black Sea1–3. Although damming is known to affect riverborne nutrient
