barrages, dikes, tide gates) are commonly constructed to prevent saltwater intrusion into upstream freshwater resources, regulate freshwater discharge, limit storm surge for flood defense and to reclaim land for agricultural use (Burt and Rees, 2001), and occasionally, to generate electricity by ...
The bay’s freshwater is distributed from over 100 small tributaries, with Hillsborough River being the largest source. The large bay averages only 12 feet depth making it a haven for a variety of wildlife. Tampa Bay is designated an Estuary of National Significance by the U.S. Environmental...
we investigated freshwater-saltwater mixing effects on dissolved carbon concentrations and CO2outgassing at six locations along an 88-km-long estuarine river entering the Northern Gulf of Mexico with salinity increasing from 0.02 at site
As observed globally, this process is facilitated by flocculation as freshwater and saltwater mix. Particulate organic matter concentrations decrease with the bulk suspended material (Macdonald and Yu 2006; Emmerton et al. 2008), and the proportion of phytoplankton contributing to the suspended organic...

The estuaries are a refuge for several nationally highly valued bird and fish species of both freshwater and saltwater ecosystems (Meire et al., 2005). 3.2.

(Hawryshyn2010). As migratory Pacific salmonids adapt from living in freshwater to saltwater (i.e., during smoltification), UV-sensitive cones undergo apoptosis to prevent retinal damage in clearer coastal environments but are later regenerated as mature adults migrate back upstream to natal habitat...
