Abstract
Based on the numerical long-wave model the run-up characteristics of the solitary waves in the bays with an U-shaped cross-sectional shape are investigated. An influence of the wave parameters and basin geometry at the run-up height of waves and the drainage depth of the coast in the narrow bays with a triangular, parabolic and rectangular cross-section is presented. It is shown that an increase of the initial wave height and the distance traveled by the wave to the shore, and a decrease of the slope angle of the coastal slope leads to a growth of the wave steepness, which in turn increases the wave run-up characteristics on the coast. The largest run-up heights of the waves are observed in the basins with a triangular cross-sectional shape, and in basins with a rectangular bottom the run-up characteristics are the least sensitive to changes of the wave parameters.
