Which outcome occurs when a major river's streamflow is significantly reduced by upstream diversion?

💡 Explanation

Increased coastal saltwater intrusion follows river streamflow reduction, because the decreased freshwater pressure allows the landward migration of saltwater; the mechanism is hydraulic gradient change. Therefore, saltwater intrusion would increase, rather than other effects on glaciers or atmospheric phenomenon.
