The tidal influence and the fluvial discharges control the water mixing, which include a salt-induced process (that is typical of all estuaries) and an acid neutralization process (pH-induced Read more about Uranium behavior during a tidal cycle in an estuarine system affected by acid mine drainage (AMD)[…]
