Water-Use in Florida

Consistent and accurate statewide water-use data are essential for the sound management of Florida's water resources. The five water management districts (WMD), which are the primary collectors of water-use information, tailor their water use programs to each of their own needs and priorities. Consequently, within the State, there are several different levels of data collection, storage,...

    Simulating wave runup on an intermediate–reflective beach using a wave-resolving and a wave-averaged version of XBeach

    The prediction of wave runup, as well as its components, time-averaged setup and the time-varying swash, is a key element of coastal storm hazard assessments, as wave runup controls the transitions between morphodynamic response types such as dune erosion and overwash, and the potential for flooding by wave overtopping. While theoretically able to...

    Observed and modeled mercury and dissolved organic carbon concentrations and loads at control structure S-12D, Florida Everglades, 2013–17

    Mercury (Hg) has been a contaminant of concern for several decades in South Florida, particularly in the Florida Everglades. The transport and bioavailability of Hg in aquatic systems is intimately linked to dissolved organic carbon (DOC). In aquatic systems, Hg can be converted to methylmercury (MeHg), which is the form of Hg that bioaccumulates...
