nutrient fluxes

sediments serve as a major carrier and storage agent for nutrients such as phosphorus, nitrogen and potassium (Baran et al. 2015). Fluxes of organisms, detritus, nutrients and other materials into reservoirs strongly affect primary productivity: denitrification, burial in sediments and nutrient turnover mean that reservoirs act as nutrient sinks, blocking the flow of nutrients downstream (McCartney et al. 2016).
