SPCMSC scientist Anastasios Stathakopoulos performs surveys on the coral-rubble keys in Dry Tortugas National Park. View is looking west from Long Key with Fort Jefferson in the background.

 The USGS coastal camera at Madeira Beach, FL was recently repaired by staff at the SPCMSC. Near real-time images are again available to be viewed on USGS webpages.

Schematic depiction of wave runup (h_runup) with its components of setup (h_setup) and time-varying swash (dashed lines). Wave runup is the time-varying elevation of water level at the shoreline, measured here in reference to the still-water level (SWL).

Image 1A. A depiction of the entire beach complex (the whole beach and dune system) which includes the beach, the dune toe (where the dune begins), and the dune crest (its highest point).

Image 6. An illustration of a beach complex showing an "overwash regime." Tides and storm surge push water up to the dune crest. Storm-induced waves then break over the top of the dune, transporting sand over the dune crest and depositing it behind the dune. The beach becomes greatly altered/degraded.

An animation of the evolution of storm impact regimes: swash, collision, overwash and inundation.

a) A schematic representation of mean water level (h₅₀) and extreme water level (h₉₈, (or total water level) referenced to a beach complex where beach slope (b_m), shoreline, dune base (z_b), and dune crest (z_c) have all been calculated.

Image 4. An illustration of a beach complex showing a "swash regime" - the relative level that the water reaches during everyday wave conditions. Water stays low on the beach and never reaches the dune toe. 

Image 5. An illustration of a beach complex showing a "collision regime" - a type of storm impact on a dune system where total water levels (including tide, surge, and waves) exceed the dune toe and break directly against the front of the dune. Loss of sand will reduce beach area for recreational use.

Image 7. This illustration of a beach complex shows an "inundation regime" where water levels exceed the beach complex and dune crest, submerging the entire beach and dune, and flooding the community behind it. An inundation regime describes the frequency, duration, and depth of tidal or storm-induced flooding in a given location.
