ON SOME PROBLEMS OF NATURAL REGIME REGULATION AND PROTECTION OF THE WORLD OCEANS SAND COASTAL AREAS

An analysis of current problems concerning natural regime regulation o f low-lying sand coasts (protection from erosion) was carried out on t he basis of native and foreign experience. Evaluation of efficiency of different coastal means of protection was made. It was emphasized tha t the following is necessary: long term repeated observations over nat ural processes and the state of natural environment in coastal areas o ver a long extent, application of determined natural regularities for selection of necessary coastal protective measures; priority use of na tural materials; artificial beaches creation and additional sediment n ourishment of existing natural ones together with building of groins ( only under specific conditions) and with possible use of different pro tective covers of shore slopes, utilization of coastline protective fu nctioning of coastal dunes; modelling of natural processes and protect ive measures; working out of an national strategy for low-lying coasta l territories protection under conditions of expected increased sea-le vel rise.
