Despite the accuracy of the figuresin this report, they should be used as indicative, and not definitive, as they arebased on an Indicative Flood Map. The limitations of this map are:
Discontinuityof the fluvial outline, due to tributaries not joining up;
Misalignmentbetween datasets, due to projection errors;
DTMerrors, due to complex automated land cover removal, and
Methodologylimitation.
The number of potentially affectedproperties is based on the estimated number of postal entries at the time of releaseof the OS Address Layer 2 dataset (April 2006) and is likely to have a high degreeof variability.
The coastline of Scotland usedin this analysis is the Ordnance Survey Boundary Line 2005 high-water mark coastline.Although it is unlikely that there are any properties located outside this coastline,the land surface between the low-water mark and the high-water mark can be considerablein places. The coastal flood zone produced by the Scottish Environmental Protection Agency does include this lands surface as well as some sea area.In the calculations, these areas were not included as coastal flood zone, or asland surface.
Other points of concern are:
Exclusionof non-postal entries in the OS Address Layer 2 dataset.
Indicativemap at scale 1/50k, not suitable to use for individual properties.
Interaction between fluvial andcoastal is not included.
