Summary:The main emphasis of their paper is on allowing greater freedom in quantifying some of the model input parameters that influence coastal response to sea-level rise (sediment supply, underlying geology, profile shape). 2006) provide two case studies of model application that demonstrate the effect of considering uncertainty in model input parameters (profile shape, geological outcrop, seawall presence, longshore sediment supply. Similarly, COOPER and NAVAS (2004) demonstrated in Dundrum Bay, Northern Ireland, that natural bathymetric change produced by sediment accumulation on the inner shelf modified the pattern of wave-sediment interactions across the surf zone. Isolating the effects of sea-level change from storms and other influences at decadal timescales has proved impossible, and no study has yet been able to demonstrate a conclusive link between sea-level change and coastal response at decadal timescales on an open ocean coast. Simple geometric models of shoreline response to sea-level change rely on a variety of assumptions regarding the relationship between wave energy, sediment grain size, and profile shape.
