Anthropogenic impacts on estuarine morphology and hydrodynamics are significant and widespread. Human modifications of riverine flow (e.g. major dams) and estuarine morphology (e.g. canalization) have the ability to substantially modify or completely disrupt natural ecoclines between catchments and the sea (de Groot 2002). These aspects then give rise to important and fundamental questions (Box 1.1).
