The shoreline around Warrenpoint has been heavily modified by human activities. These involve shoreline advance associated with port infrastructure and construction of the promenade on former intertidal flats. The Pier present in the 1830's was progressively extended but in the mid-20th century large scale reclamation extended the shoreline to its present position. To the east, shoreline armour along the Rostrevor Road has stabilised the shoreline. |
Shoreline changes in this area are the result of deliberate human activities. |
The shoreline position is fixed by various sea defences. |
While the shoreline position has been fixed, rising sea level is likely to cause more frequent overtopping of sea defences and will reduce the width of intertidal flats through coastal squeeze. |

This stretch of coast contains alternating sections of natural shoreline promontories separated by stetches where the road is at the shoreline. The road has been defended and its shoreline stabilised. The intervening promontories show general stability in shoreline position, although there is some natural shoreline advance in places where inflowing streams have added sediment to the coastal system. |
Stabilised sections front the main road while natural shorelines appear to be advancing or remaining stable through ongoing sediment supply. |
The deltas at the mouths of inflowing streams are actively advancing. |
The sea defences are likely to remain and stabilise the main road. The rates of advance on natural promontories may reduce as sea level rises and historically stable natural sections may begin to exhibit erosion. |

The shoreline has generally advanced in the historical period, partly through natural processes and partly by artificial reclamation. Shoreline advance is particularly pronounced around the mouths of inflowing rivers. This advance has been sustained throughout the historical period. |
The shoreline changes reflect an abundance of sediment from the inflowing rivers and a tendency to advance. The shoreline has, however, been altered quite considerably by the construction of sea defences in attempts to stabilise it. |
The present shoreline comprises a variety of armoured and natural stretches. Some armoured sections have experienced shoreline advance in front of the armour, while others are static. The natural stretches of shoreline are generally advancing due to continued sediment input from small rivers. |
Sea level rise may slow rates of shoreline advance and cause erosion on some stretches. Coastal squeeze in areas backed by armoured shorelines may reduce the width of intertidal flats and beaches. |

This stretch of the northern shore of Carlingford Lough has shown general stability over the historical period. In some sections this is attributable to sea defences built to protect the main road and other structures, but non-armoured stretches have also shown generally small amounts of change. At Killowen Point the shoreline has advanced seaward since the 1830s. |
The low rates of change can be attributed to low energy conditions and possible alongshore movement of sediment from adjacent stream mouths. Accretion on the eastern side of Killowen Point suggests easterly alongshore movement of sediment in this stretch that accumulates at Killowen Point. |
The main road follows the shoreline and is likely to continue to be defended in the event of future changes. |
The long-term stability may change to a more erosive condition, but defence of the road is likely to mean continued stability in shoreline position. |
