Abstract
The response of coastal sand bodies to sea level rise can be modelled using computer simulation of large scale coastal behaviour based only on principles of sand-mass conservation and geometric rules for shoreface and barrier morphology. The model simulates horizontal and vertical translation of coastal sand bodies over the pre-existing coastal substrate which undergoes reworking as a consequence. This produces changes in position of the coastline as well as reconfiguration of the backshore and inner-continental shelf morphology and stratigraphy. Application of the model is illustrated with examples from mineral exploration of the continental shelf and assessment of coastal erosion risks in the face of sea-level rise due to the enhanced greenhouse effect.
