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 loads, and thus riverine ecosystems, evidence for significant effects in open coastal waters is sparse4–6. Here we present long-term data sets of water and nutrient discharge from the River Danube to the Black Sea. These data reveal a reduction in the dissolved silicate load of the river by about two… 
Silicon Retention in River Basins: Far-reaching Effects on Biogeochemistry and Aquatic Food Webs in Coastal Marine Environments
TLDR
Regulation of rivers by damming as well as eutrophication in river basins has substantially reduced dissolved silicon loads to the Black Sea and the Baltic Sea, resulting in changes in the nutrient composition of river discharges.
DISSOLVED SILICATE CHARACTERISTICS IN KINOKAWA RIVER BASIN
Nitrogen and phosphorus have been treated as important substances related to the eutrophication and the water quality such as red tide. However, silicon is one of substance to compose an organic
Long-term changes in the Changjiang Estuary plankton community related to anthropogenic eutrophication
The Changjiang River is well-known to channel significant anthropogenic influences to the estuary. However, long-term changes in plankton community related to anthropogenic eutrophication in the
Biogenic silica accumulation in the sediments of Iron Gate I Reservoir on the Danube River
Abstract.Damming of rivers can result in severe downstream effects such as changing sediment and nutrient fluxes that potentially affect coastal ecosystems. Closing of the Iron Gates Dams in the

Hydrological alterations with river damming in northern Sweden: Implications for weathering and river biogeochemistry
This case study tests the hypothesis that damming leads to a depletion of major elements in river systems. It determines the effect of river dams on the weathering regime, and thus on dissolved

The Possible Importance of Silicon in Marine Eutrophication
TLDR
Arguments are presented that silicon is often the controlling nutrient in altering a diatom to a flagellate community and examples of such alterations are presented for oceanic, estuarine and inland water bodies.

Abstract There is a need in the marine research and management communities for a clear operational definition of the term, eutrophication. I propose the following: This definition is consistent with
