Flows in and out of rivers and estuaries often generate dynamic frontal features due to localized sharp gradients in the currents, density, or bathymetry. Fronts often coincide with a narrow region of strong flow convergence, resulting in significant downwelling velocities and an increased surface roughness that make the fronts visible in remote sensing images. Within these energetic frontal zones and the shear layer at the density interface, shear instabilities are also common (Geyer et al., 2010;Horner-Devine et al., 2015;Smyth et al., 2001). These flow structures can enhance mixing and entrain bubbles and suspended particulate matter, affecting the lifecycle of the plume, acoustic sensor performance, and underwater vehicle operation.Remote sensing can be effective at identifying and tracking density fronts and frequently shows the existence of along-front spatial structure (

“…Field observations suggest that wave energy dissipation during low tide is associated with maximum swash distribution [18,19]. Laboratory and field results indicate that different types of wave breaking also influence wave runup and swash distribution [7,15,16,[20][21][22]. New evidence demonstrates that swash motions, related to reflection and breaking, force the long-wave [23][24][25][26][27].…”

Swash motions are important for the design and assessment of beach protection projects, while the limitation of insightful observations in the swash zone still exists. An automatic identification method based on video imagery is developed to monitor and extract instantaneous swash motions in the laboratory. The method increases video sampling frequency and improves image enhancement in identification. The improved method fits well with the results of the manual method. The incident band roll-off of the swash spectrum in the experiment is consistent with those observed on natural beaches. Results have shown that on the barred beach, water depths influence the peak frequency in the incident band and cause a multi-peak swash spectrum. A large incident wave period causes a low peak frequency but high peak energy in the swash spectrum. Large incident wave height results in wider energy coupling, making swash to be saturated and more energy in swash energy. The existence of a barred beach promotes swash energy transferring from a high frequency to a low frequency.
