CLYDE MAP 5: WHITE CART BRIDGE to ERSKINE HARBOUR

Hinterland Geology and Coastal Geomorphology: The hinterland is dominated bymarine deposits formed in a very low lying riverine delta. The land may have beenreclaimed as it lies below a flood bank. Freshwater alluvial and estuarine silts arepresent along the banks of the River Cart. Embankments defend land formed by thereclamation of salt marsh as far as the Erskine Harbour. Erosion Class: This coastal cell was found to contain sections that were seriouslyeroding. The coastline along Newshot Island consists of salt marsh that is eroding asa result of wave impact. The low cliff is approximately 1.5-2m high and is undercutat several places. Small islands of saltmarsh stand in isolation as the cliff is retreating.Erskine Harbour is experiencing accretion as it is acting as a focus for sedimententrapment. Built Heritage & Archaeology: This cell contains a variety of remains, ranging froma possible fishing weir to a stone jetty and possible loading platforms. Park Quay hasfallen into disrepair but, judging by its proportions, was once quite an important dockfor medium sized boats. Numerous timber hulks are present. Erskine Harbour is alsoin a poor condition, as it has been allowed to become overgrown and silted up.Newshot Island is part of the salt marsh that has not been reclaimed behind theembankments along the Clyde. The reclamation works dominate the land at thewestern end of this cell, and landscaping works have been carried out around the ParkQuay area.
