Slope type hydraulic structures are widely used in the construction. They are used both as fencing and as shore protection and are usually located on the coasts of offshore water zones. The interaction of such structures with external loads has been studied for quite a long time. The methods of calculating these structures have been developed. Defining the wave run-up height on a slope of a structure can be considered the main question in the calculation of these structures. The given article provides a brief survey of the methods of calculating the wave run-up height on slope of structures of various applications. These methods were developed on the basis of experimental studies. The author examines various solutions to this problem, previously obtained by different researchers.In order to calculate the wave run-up height on a slope type shore protection construction a large number of calculation methods were developed. The parameters of a wave approaching a structure were defined by linear or non-linear wave theory, but they are mostly true in the conditions of a smooth slope with constant gradient. In the case of complex slope configuration physical modeling is currently used.Slope structure having more complicated form can solve many problems, such as: reducing the crest level, increasing the slope stability, creating more aesthetically appealing appearance of the structures, but their calculation and design is currently difficult, since there is practically no reliable method of calculation and, therefore, it requires significant investment.At present the solution to this problem is relevant and necessary.<br>Гидротехнические сооружения откосного типа широко распространены в практике строительства. Они используются как оградительные, так и берегозащитные и, как правило, расположены на побережьях открытых акваторий.Изучение взаимодействия этих сооружений с внешними нагрузками ведется достаточно давно. Разработаны методики расчета данных сооружений. Основным вопросом при расчете данных сооружений можно назвать определение высоты наката волны на откос сооружения.Приведен краткий обзор методов расчета высоты наката волн на откосы сооружений различного назначения. Эти методики разрабатывались на основе экспериментальных исследований. Рассмотрены решения данной задачи, полученные ранее различными исследователями.
