The field sites have been selected to investigate the links between biophysical properties of coastal foreshores, wave-attenuation and foreshore stability indicators. The combination of satellite images and field work will allow near real time estimates of both the stability and the wave dissipation of estuarine areas.

[The Netherlands]  Westerschelde. Estuarine fringing marshes are fronted by an extensive, gently sloping intertidal mudflat (4.7 m tidal range). Saltmarshes are either net accreting or net eroding.

[UK] Tllingham and Donna Nook. Open coast area of marsh fronted by extensive, gently sloping mud- and sand flats (5.7 m and 7.5 m tidal range respectively). Tillingham marshes have been eroding throughout the past 50 years, whereas Donna Nook ones have been accreting over the past 20 years. Both sites have a high degree of wave exposure.

[Romania]  Danube Delta Biosphere Reserve coast. Sandy barrier beaches at the interface between the Danube River and the Black Sea (< 0.1 m tidal range) with constant erosion during the past decades under the impact of storm waves.

[Spain] Cadiz bay. This site is within a shallow coastal bay (3.7 m spring tidal range). The fringes of the bay are highly urbanised. Tidal flats that are dominated by seagrasses are found in front of salt marshes. Main wave source is wind.
