The Input of Geomorphology to Oil-related Developments in Shetland and Northeast Scotland

RITCHIE, WILLIAM, University of Aberdeen, Aberdeen, U.K.

In essence, the input of coastal geomorphology to most oil-related developments at the coastline has been descriptive environmental classification. The uses to which this information has been put are twofold: (1) as background reconnaissance data that are prepared in advance of a development, such as the exploitation of a nearshore drilling lease or a pipeline landfall, and (2) as a basic element in oil spill contingency mapping. A more specialized use of geomorphology has been environmental management advice relating to the construction, restoration, and operation of large-diameter oil and gas pipeline landfalls--all of which make their approach in Northeast Scotland through beach and dune complexes.

The techniques consist of traditional morphological mapping, considering form, aspect, materials, energy, and estimations of contemporary processes. Implicit in this mapping is the recognition of vulnerability which, in turn, relates closely to habitat recognition. Time is rarely available for process-type measurements. There is also a dependence on existing maps, aerial photographs, and reports. The survey may be done on foot, from boats, fixed-wing aircraft, or helicopters. Airborne video is increasingly being used as a supplementary means of data acquisition. Vertical airborne video used with an image-processing and G.I.S. system shows great potential and has been used experimentally for pipeline route selection.
