Hydrology

Estuaries and Land Runoff

As part of the hydrological cycle, freshwater runs off the land and into the ocean – fueling ocean ecosystems with food and nutrients as well as affecting currents and stratification in coastal waters. Changes in the volume and timing of this runoff, as well as in the particulate and dissolved load, have a profound effect on coastal and estuarine waters with impacts on fisheries, ecosystems, wildlife and human health.
