Excessive nitrogen that mixes with rivers and estuaries can profoundly affect water systems; for example it can spur algal blooms, which have negative impacts on human health, aquatic ecosystems and the economy. Future changes in precipitation patterns, induced by climate change, could strongly influence the degree of future n…
