TL;DR: In this article, a comparison is made on wave directions estimated based on first and second order Fourier coefficients using data collected at four locations in the west and east coasts of India at all locations, the mean and principal wave directions for frequencies ranging from 0.07 to 0.25 Hz co-vary with a correlation coefficient of 0.99 but at lower and higher frequencies, difference between the parameters is large.

Abstract: Landslide-related impulse waves are catastrophic but accidental, so limited data on field measurements are available; scaled physical experiment is therefore a functional method to simulate and analyze this phenomenon. A large-scale physical Froude-similar model to produce impulse waves was constructed based on the Chinese Gongjiafang landslide, which occurred on the main stream of Three Gorges after the impounding in the reservoir in China. With a scale of 1:200, the model had the dimensions of 24, 8, and 1.3 m. Four water levels, 145, 156, 172.8, and 175 m, were modeled for the experiments, and marble coarse sands were used to imitate the actual cataclastic rock mass. Wave height gauges, high-speed cameras, and run-up measuring instruments were used to monitor wave fluctuations in the model. Among the experiments, the ones modeled using a water level of 172.8 m best confirmed the actual conditions in the Gongjiafang landslide, representing a good validation of the experiments. This study obtained, for the first time, specific data on the reproduced impulse waves’ convergence and superposition during propagation, and of the energy change between impulse waves and reflected waves. The test data describe a rapid decaying and gradual decaying rule for the wave heights and run-ups. The Froude-similar experiments presented in this article help us to understand the whole procedure of impulsive wave generated by cataclastic rock mass failure, and the results acquired contribute to studies of impulse waves caused by similar bank destabilizations worldwide.

TL;DR: In this paper, the effect of wave height, wave period, porosity and the number of walls on the reflection coefficient was investigated and an array of slotted vertical barrier arranged in a zigzag manner was found to be an effective mechanism for enhancing the wave energy dissipation, more space creation and a significant reduction in material requirement and easy installation procedure.

TL;DR: In this article, the authors presented the benchmark simulations of wave run-up on a fixed single truncated circular cylinder and four circular cylinders, where the Navier-Stokes equations are employed as the governing equations, and the volume of fluid (VOF) method is applied for capturing the free surface.

TL;DR: In this article, a semi-empirical method is developed which predicts the wave height shoaling up to the break point on laboratory and natural beaches, which is enhanced with empirical curves for the wave shape, obtained from field measurements of wave height through the break points and the surf zone made on an ocean beach in southern Australia from 1987 to 1989.
