Summary: This paper investigates the runup of a train of successive solitary waves through experiments and numerical simulations. It categorizes the runup characteristics of successive solitary waves into weakly interacting and strongly interacting cases based on the nonlinearity parameter. The study finds that the unified empirical runup formula for single breaking solitary waves and breaking periodic waves can be applicable to obtain the maximum runup height of successive solitary waves.

Summary: This study investigates the effects of bed roughness and beach slope on non-breaking solitary wave runup height through laboratory experiments. The results show that bottom friction plays different roles for different beach slopes. A new empirical model is proposed to estimate runup height based on the maximum runup height, bed roughness, beach slope, and enhancement and reduction coefficients. The model is validated using existing data and shows good agreement with measurements.

Summary: This paper addresses the lack of measurements on pocket gravel beaches in limited-fetch environment, especially in the Mediterranean region. The study examines the alongshore variability of wave runup on the pocket beach of Ploce, Croatia, and compares wave runup predictions from five empirical equations with field measurements. The best performing equation is further refined and shows improved accuracy for wave runup prediction in similar environments.

Summary: This study investigates the variability of wave runup caused by wave sequencing through laboratory experiments. The results show that there is considerable variability in wave runup among wave groups, which is greatly influenced by the incident wave conditions.

Summary: In Fall 2015, a large, low-pressure Nor'easter storm and Hurricane Joaquin caused sustained elevated wave and water level conditions along the southeastern Atlantic coast of the United States for multiple weeks. Sea level anomalies exceeding 1 m and offshore wave heights up to 4 m were recorded, resulting in highly variable morphologic changes to the dune over short spatial scales.

Summary: This study conducted 122 experiments to investigate the breaking of solitary waves on smooth and rough slopes. By measuring free surface elevations, velocities, and maximum runup heights, it was found that the roughness of the slope significantly affects the runup of solitary waves.

Summary: This paper numerically studies the overtopping characteristics of coastal seawalls under the combined impact of onshore wind and solitary wave, and discusses the influences of some main factors. The results show that the presence of onshore wind greatly affects the runup and the amount of overtopping water of seawalls under the action of solitary wave.

Summary: This study aims to provide a method for quantifying the relationship between beach slope and wave runup and inundation, as well as the impact of different hydrodynamic mechanisms on runup under different beach states. Through an 8-month field study on a beach in southwestern Australia, an approximately linear relationship between inundation and runup was identified by considering beach slope. It was found that swash dominated runup in the infragravity band when the beach was accreted, while setup dominated runup when the beach was exposed.

Summary: Solitary waves are often used to study the hydraulic characteristics of tsunamis, but they have narrower distribution and smaller volume compared to actual tsunamis. A new method called tsunami-like wave generation is proposed to improve the representation of wide-waveform tsunamis. Numerical analysis is conducted considering various waveforms, and the differences between solitary waves and tsunami-like waves are explored.

Summary: Theoretical solutions show that the amplitude of soliton resonance can be four times larger than the incident solitary wave. Interaction of multiple solitary waves in shallow water results in O-type resonances. The study validates these interactions through theoretical solutions and numerical simulations.

Summary: Publicly available satellite imagery can offer multi-decadal time series of shoreline data, but uncertainties may arise, especially for beaches with large tidal range and energetic waves. This study at a high-energy beach in France highlights the importance of considering water level and wave runup in accurately estimating shoreline position. Implementing wave runup and a new water level threshold can improve the accuracy of satellite-derived shoreline positions and increase the number of usable images.

Summary: Wave runup and its components are crucial for coastal storm hazard assessments. The XBNH model outperforms the XBSB model in predicting wave runup, mainly due to better predictions of incident-band and infragravity-band swash movements.

Summary: This paper presents numerical simulations for the runup of solitary-like waves on a sloping beach and circular island and validates the model accuracy. Different elongation parameters show varying effects on the waveform of the solitary-like wave. The study reveals that abnormal rear runup may exceed front runup in certain cases.
