A coastal domain is a segment of coastline that possesses a character defined by the sum of its basic morphological characteristics (e.g. platform, barrier, estuary) and geological properties and behaviour (e.g. weak strata, resilient strata, structure). This dataset groups sections of coastline based on the susceptibility of the coastline to erosion and the presence or absence of a buffer between direct wave action and the coastline geology.
