Abstract: Please click here to download the map associated with this article. A map of shoreface morphodynamic behaviour, from 2–23 m water depth, off Portstewart Strand, the north coast of Ireland, is presented. The map is generated in order to provide a spatial visualization of shoreface dynamics along a high-energy coastal segment from March to July 2005. The map indicates portions of the seafloor that have either eroded (shown in scales of red), remained unchanged (no color) or accreted (indicated in scales of grey). The change is in the vertical and provided in meters. The map clearly shows that the nearshore zone (2–5 m, O.D.) is the most dynamic, explained by the fact that this is where most energy is concentrated as waves approach and break. The ability to combine Geographical Information Systems (GIS), Global Positioning Systems (GPS) with periodic bathymetric surveys enhances our understanding of nearshore and shoreface morphodynamics.
