В настоящее время глобальной особенностью береговой зоны Мирового океана является повсеместная активизация эрозионных процессов. Наиболее быстрые и масштабные изменения характерны для аккумулятивных берегов. В представленной работе проанализирована динамика берега морского края дельты р. Хонгха (Вьетнам) на протяжении последних 100 лет. Дана информация о современном состоянии некоторых участков берега и применяющихся способах защиты от наводнений и размывов.
In present time the intensification of erosion processes is global feature of coastal zone and the most rapid and significant changes are characteristic for accumulative coasts. The features of the sea coast dynamics of the Hong Ha River delta (Vietnam) during last 100 years are analyzed in presented paper. The Hong Ha River delta coast modern dynamics is characterized by combination of accumulation processes near delta mouths and wave erosion between its. The main factors determining the modern dynamics of the delta sea coast are the wave activity with the surge-tidal fluctuations and solid runoff reduction. Current coastal construction cannot protect populated areas from flooding. Reorientation to the integrated coast construction which includes the beaches is realized. Control of Hong Ha river delta coastal erosion is difficult and long-range objective in the framework of the integrated coastal management.
