Исходными данными служат характеристики профиля берега, размеры сооружения и суммарные годовые потоки наносов. Контур берега с обеих сторон препятствия описывается в общем случае вогнутой кривой. Среднее смещение береговой линии  A  прямо пропорционально объему наносов, аккумулированному у сооружения. Протяженность зоны воздействия на берег  Λ  зависит как от длины сооружения, так и от ширины потока наносов. С течением лет t смещение  A  и длина  Λ  увеличиваются пропорционально √t . Проверка модели проведена на основе опубликованных данных, относящихся к молам, ограждающим подходной канал или акваторию порта. Приведен пример расчета.</p></abstract><trans-abstract xml:lang="en"><p>A model is suggested to predict the shoreline changes in the vicinity of coastal structures of the type of jetty, cofferdam or groin. Input data comprise the characteristics of coastal profile, dimensions of structure and the annual alongshore sediment fluxes. Shoreline contour from each side of the obstacle is described in general by a concave curve. Mean shoreline displacement A is proportional to the sediment volume trapped by a structure. Extension Λ of the area where the structure influences the shoreline contour depends on both the length of structure and the width of sediment flux. Displacement A and the length Λ tend to increase with the time t in proportion to √t . Verification of the model is based on the published data on shoreline changes due to a jetty protecting a navigational channel or a port basin. An example of model calculation is given.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>контур берега</kwd><kwd>поперечное сооружение (мол</kwd><kwd>буна</kwd><kwd>коффердам)</kwd><kwd>зона  влияния сооружения</kwd><kwd>вдольбереговой поток наносов</kwd><kwd>смещение береговой линии</kwd><kwd>аккумуляция</kwd><kwd>размыв</kwd></kwd-group><kwd-group xml:lang="en"><kwd>shoreline contour</kwd><kwd>cross-shore structure (jetty</kwd><kwd>groin</kwd><kwd>cofferdam)</kwd><kwd>zone of structure influence</kwd><kwd>longshore sediment flux</kwd><kwd>shoreline displacement</kwd><kwd>accretion</kwd><kwd>erosion</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">РФФИ (проекты  № 15-05-08239, № 16-05-00364А и № 16-55-76002 ЭРА_а).</funding-statement><funding-statement xml:lang="en">RFBR (projects №№ 15-05-08239,  16-05-00364A  and 16-55-76002 ERA_a).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pelnard-Considére R.
