1. What is the scientific classification?Estuarine salinization phenomenon
2. What is the primary causal mechanism?Reduced freshwater discharge allowing tidal saltwater intrusion

Salt tide: A temporary condition where saline ocean water invades the lower reaches of a river due to low freshwater flow.
Estuarine salinization: The process by which estuaries become saltier, often influenced by tidal forces and reduced river input.
River discharge: The volumetric flow rate of water passing through a river's cross-section, a key determinant of freshwater influence.
Salinity: A measure of the total concentration of dissolved salts in water, typically expressed in parts per thousand (ppt) or milligrams per liter (mg/L).
