This paper presents new laboratory data on long-wave (surf-beat) forcing by the random breaking of shorter gravity water waves on a plane beach. The data include incident and outgoing wave amplitudes, together with shoreline oscillation amplitudes at long-wave frequencies, from which the correlation between forced long waves and short-wave groups is examined. A detailed analysis of the cross-sh...

Ocean waves provide a vast, uninterrupted resource of renewable energy collocated around large coastal population centers. Clean from ocean can contribute to the local electrical grid without need for long-term storage, yet due current high cost extraction waves, there is no commercial wave farm in operation. One converter (WEC) device classes that show potential enable economic generation clas...

This paper shows simulations of high waves over different bathymetries to collect statistical information, particularly kurtosis and crest exceedance, that quantifies the occurrence exceptionally extreme waves. knowledge is especially pertinent for design operation marine structures, safe ship trafficking, mooring strategies ships near coast. Taking advantage flexibility perform numerical with ...

The weakly reflective wave generation is a and absorption method in phase-resolving models, based on the assumption that waves propagating towards boundary are small amplitude shallow water with direction perpendicular to boundary. This makes for dispersive directional waves. internal was proposed by Vasarmidis et al. (2019b) as an alternative, non-hydrostatic model, SWASH, avoid reflections. I...

Current ecological surveys for great crested newts are time-consuming and expensive and can only be carried out within a short survey window. Additional survey methods which would facilitate the detection of rare or protected species such as the great crested newt (Triturus cristatus) would be extremely advantageous. Environmental DNA (eDNA) analysis has been utilized for the detection of great...

Our knowledge of the causative agent of rat-bite fever is of recent date. Futaki and his associates reported in their first communication the finding of a long spirochete, measuring 9 to I0/z in the lymph glands on the 10th or 13th day of illness, and on the 33rd day in tissue fluid obtained from the bitten area. Those found in the lymph exudate had small waves, those from sections of lymph gla...
