Predictions of future requirements for the protection of maritime archaeological sites are made using the fetch method which has been developed to evaluate the quality of landing-places and navigable channels. The very useful method may explain why archaeological sites along the coast are rare in some areas, but numerous in others. Many of them are vulnerable to destruction by the effects of climate change, especially rising sea-levels, based on the IPCC scenarios. The objective fetch method can be used worldwide to predict where new finds of sites close to sea-level can be expected, and also to predict a site's vulnerability.
