Long-term hydrological observations of the Kudepsta River formed the basis for a comprehensive study of the water body. Application of modern geoinformation technologies and statistical analysis method, large-scale field surveys of river channel processes allowed to justify the method of flood protection of the Kudepsta River coastal lands. As a result of the survey of the Kudepsta River channel section in the area of Kudepsta settlement and calculations of shoreline displacement, it was proposed to apply a flexible gabion structure to strengthen the right bank part of the river. This design demonstrates high efficiency of protective measures against erosion and waterlogging of the coastal strip. The estimation of economic efficiency of the method of bank protection is carried out, as a result the coefficient of economic efficiency is equal to 1.77, which is economically favorable. The payback period of construction will be 1 year. Practical experience in the implementation of such engineering solutions can be widely used in the implementation of bank protection works on mountain rivers in various subjects of the Russian Federation.</p> <p>Purpose. Objective of the study to investigate the method of protection of the coastal lands of the Kudepsta River in case of emergency situations.</p> <p>Materials and methods. The study area is located on the right bank of the Kudepsta River, its length is 358 meters. The site is located in the mouth of the Kudepsta River valley – it is a right bank section of the river, which is represented by a terrace with an overflow exposed ledge with a height of 2 to 5 meters. It is characterized by degradation associated with landslide processes occurring in the riverbed</p> <p>Results. To prevent flooding of the adjacent territory and erosion of the banks of the Kudepsta River in the study area it is necessary to build a retaining wall 5.0 m high, 358 m long from gabion structures. Bottom reinforcement of the channel bottom is provided taking into account the possibility of its erosion and in order to protect the erosion funnel.</p> <p>Conclusion. Based on the survey of the Kudepsta River channel section and shoreline displacement calculations, flexible gabion structures should be used to reinforce the right bank part of the river. This design demonstrates high efficiency of protective measures against erosion and waterlogging of the coastal strip. A method of coastal protection to prevent flooding of the adjacent territory and erosion of the banks of the Kudepsta River at the research site by means of a retaining wall 5.0 m high, 358 m long made of soft gabion structures is proposed.</p></abstract><trans-abstract xml:lang="ru"><p>Обоснование. Многолетние гидрологические наблюдения на реке Кудепста легли в основу комплексного исследования водного объекта. Применение современных геоинформационных технологий и метода статистического анализа, масштабные натурные обследования русловых процессов реки позволили обосновать способ защиты от наводнений прибрежных земель реки Кудепста. В результате обследования участка русла р. Кудепста в районе поселка Кудепста и расчетов смещения береговой линии предложено применить гибкую габионную конструкцию при укреплении правобережной части реки. Данная конструкция демонстрирует высокую результативность защитных мероприятий против размыва и подтопления береговой полосы. Выполнена оценка экономической эффективности способа берегозащиты, в результате получен коэффициент экономической эффективности равен 1,77, что является экономически выгодным. Срок окупаемости строительства составит 1 год. Практический опыт реализации подобных инженерных решений может найти широкое применение при выполнении берегозащитных работ на горных реках в различных субъектах Российской Федерации.</p> <p>Цель. Цель исследования – изучить способ защиты прибрежных земель реки Кудепста при возникновения чрезвычайных ситуаций</p> <p>Материалы и методы. Исследуемый участок находится на правом берегу реки Кудепста, его протяжённость 358 метров. Участок расположен в устьевой части долины реки Кудепста – это правобережный участок реки, который представлен террасой с надпойменным обнажённым уступом высотой от 2 до 5 метров. Характеризуется деградацией, связанной с оползневыми процессами, происходящими в русле реки</p> <p>Результаты. Для предотвращения подтопления прилегающей территории и размыва берегов реки Кудепста на участке исследований необходимо устройство подпорной стены высотой 5,0 м, протяженностью 358 м из габионных конструкций. Низовое укрепление дна русла предусматривается с учетом возможности его размыва и из условия защиты воронки размыва.</p> <p>Заключение. Исходя из обследования участка русла р. Кудепста и расчетов смещения береговой линии необходимо применение гибких габионных конструкций при укреплении правобережной части реки. Данная конструкция демонстрирует высокую результативность защитных мероприятий против размыва и подтопления береговой полосы. Предложен способ защиты прибрежных территорий для предотвращения подтопления прилегающей территории и размыва берегов реки Кудепста на участке исследований, путем устройства подпорной стены высотой 5,0 м, протяженностью 358 м из мягких габионных конструкций.</p></trans-abstract><kwd-group xml:lang="en"><kwd>flood</kwd><kwd>bank stabilization</kwd><kwd>gabion structures</kwd><kwd>water flow</kwd><kwd>channel deformations</kwd><kwd>scouring</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>паводок</kwd><kwd>берегоукрепление</kwd><kwd>габионные конструкции</kwd><kwd>водоток</kwd><kwd>русловые деформации</kwd><kwd>размыв</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Boukhanef, I., Khadzhidi, A., Kravchenko, L., et al.
