Carmarthen Bay: Evolution of Estuarine Morphology and Consequences for Special Area of Conservation (SAC) Management
Carmarthen Bay has a total of four important estuaries comprising the Loughor Estuary and the Taf, Towy and Gwendraeth. Between 16th and 19th century these estuaries lost around 2400 Ha of saltmarsh due to land claim. Between the end of the 19th century and end of the 20th the estuaries gained 1136 Ha. The changes in the saltmarsh environment may impact shellfish, invertebrates and wading birds. The purpose of this data capture was to investigate the history of evolution and current trends in the geomorphological development of the estuaries of the then Carmarthen Bay and Estuaries candidate Special Area of Conservation (cSAC). Carmarthen Bay and Estuaries is now designated fully as an Special Area of Conservation (SAC) for numerous species and habitats including estuaries, mudflats, sand flats and lagoons, which make up 13.7% of the site.

Methods of data capture: Various information regarding each of the estuaries were obtained including shoreline monitoring profiles, bathymetry contours, mean high water and mean low-water locations extracted from OS Landline data. Physical characteristics of the estuaries were obtained; such as their geology, evolution of coastal barriers, past and present estuary area, tidal regimes, tidal prism, river discharge and tidal flushing. Sediment supply was further investigated as well as historical changes in channel pattern. A cross sectional profile of each estuary was created.
