Coastal evolution over centuries to millennia requires a broader outlook than for shorter time and space scales, in that the shoreline evolution must be linked to the behaviour of the continental shelf and coastal plain (Cowell et al., 2003a[1]). The coastal tract is the combination of lower shoreface, upper shoreface and back barrier that comprises the first-order system within a coastal tract cascade, whereby greater and greater levels of detail are needed to model coastal evolution at shorter and shorter time-scales and space-scales (Figure 1). The coastal tract cascade formalises concepts for separating coastal processes and behaviour into a scale hierarchy. An additional concept, that of coastal tract templating was also introduced by Cowell et al. (2003b[2]) to provide a protocol for defining a site-specific problem by transforming data into a data model.
The aggregate dynamics of the coastal tract are modelled using behaviour-orientated coastal change models and constrained by sediment mass conservation. The rate of coastal advance is governed by the balance between the change in sediment accommodation space caused by sea level rise and sediment availability.
