Summary

Cork Harbour, a large natural harbour of strategic importance, is situated on the south coast of Ireland. Cork Harbour, with a surface water body of 100km2, extends from the tidal influence of the River Lee to the narrow Harbour mouth. Cork Harbour is a large, sheltered, naturally deepwater harbour. Strong estuarine influences dominate the upper reaches of the Harbour in particular. The coastline is mixed, consisting of built infrastructure, shallow cliffs, intertidal mudflats, reedbeds, shingle and rocky foreshores, which are exposed by the tide (tidal range 3-4m). The bathymetry of the Harbour reflects the morphology of the coastline, with gentle slopes dropping to a depth of 28m near the mouth of the Harbour (11m in the channel which is maintained at that depth for navigation).

Riverine inputs originate from the Lee, the Owenacurra, the Glashboy and the Owenabue. Freshwater inputs from the Lee are controlled by the dam upstream at Iniscarra. Nutrient loading is primarily from non-point agricultural sources distributed throughout the catchment, but primarily in the upper reaches of the Lee estuary. Point source discharges have been reduced by the recent Cork main drainage scheme.

While contemporary use of large tracts of the Harbour is marked by concentrations of urban populations (most significantly, Cork City – population ~123,000) and widespread chemical and pharmaceutical industries, much of the coast remains unspoilt and characterised by rural agricultural land use or protected habitats. It’s sheltered environment and deep-water channels make Cork Harbour an ideal location for shipping and recreational boating activities. The physical geography of the Harbour on the south coast of Ireland provides a strategic location for the Port of Cork situated in close proximity to the main shipping line to Northern Europe. Tourism, marine heritage, fishing, and waste management are other key human activities associated with the harbour

Policy issues:

Policy changes:

Characteristics

Marine System

Cork Harbour, with a surface water body of 100km2, extends from the tidal influence of the River Lee to the narrow Harbour mouth. Cork Harbour is a large, sheltered, naturally deep- water harbour. Strong estuarine influences dominate the upper reaches of the Harbour in particular. The coastline is mixed, consisting of built infrastructure, shallow cliffs, intertidal mudflats, reedbeds, shingle and rocky foreshores, which are exposed by the tide (tidal range 3-4m). The bathymetry of the Harbour reflects the morphology of the coastline, with gentle slopes dropping to a depth of 28m near the mouth of the Harbour (11m in the channel which is maintained at that depth for navigation).

Watershed

Riverine inputs originate from the Lee, the Owenacurra, the Glashboy and the Owenabue. Freshwater inputs from the Lee are controlled by the dam upstream at Iniscarra. Nutrient loading is primarily from non-point agricultural sources distributed throughout the catchment, but primarily in the upper reaches of the Lee estuary. Point source discharges have been reduced by the recent Cork main drainage scheme.

Human Activities

While contemporary use of large tracts of the Harbour is marked by concentrations of urban populations (most significantly, Cork City – population ~123,000) and widespread chemical and pharmaceutical industries, much of the coast remains unspoilt and characterised by rural agricultural land use or protected habitats. It’s sheltered environment and deep-water channels make Cork Harbour an ideal location for shipping and recreational boating activities. The physical geography of the Harbour on the south coast of Ireland provides a strategic location for the Port of Cork situated in close proximity to the main shipping line to Northern Europe.

Tourism, marine heritage, fishing, and waste management are other key human activities associated with the harbour.

Impact Responses

Eutrophication, water pollution, contaminated land, flooding and use conflict.

Research Projects

The COREPOINT (Coastal Research and Policy Integration), INTERREG IIIB, initiated in 2004, uses Cork Harbour as a strategic study site. Local policy issues are investigated through enhanced scientific understanding of natural processes within the harbour. These include reserach into physical coastal processes influencing vulnerability to flooding.

Cork Harbour has also been mapped as part of the Irish National Seabed Suvey. The resulting data is used in a national project to advance the development of integrated coastal zone maps. The Blue City Project – use of Information Technology to study Cork City’s water resources, (Higher Educational Authority funded), is also nearing completion.

Socio-economic study

Several socio-economic studies have been undertaken including: studies relating to Port of Cork Strategic Development, the Economic Impact of the Port of Cork’s Cruise Traffic, the Economic Contribution of the Port of Cork to the Irish Economy and a case study on the Economic Significance of Ford Cork Week 1996 Sailing Regatta.
