The response of the water table of an intertidal salt marsh in NW England has been investigated. During neap tides, water seeps upward from the underlying sand-silt-clay interface. This effect continues as the marsh is overtopped during spring tides but is then dwarfed by penetration of water downward from the surface. Under “typical conditions” the delay between high water in the river and max...

Internal tides commonly occur along ocean coasts. They are internal waves driven by the usual tidal force and generated by scattering at a sharp bottom feature such as the shelf break. The internal tides are dramatic features with crests typically 10-30 km apart and wave heights of 20 m. On the ocean surface they cause only a gentle ripple about 10 cm high but they affect the shine of the surfa...

Abstract In the sixteenth century, Cornaro wrote a Treatise on Waters with personal observations and conclusions regarding Lagoon of Venice, e.g., sea level rise over centuries, difference between normal tides for astronomical forces storm surges driven by meteorological factors, water exchanges Sea. He witnessed continuous since Middle Ages listed some public works made to adapt this challenge...

In addition to the tsunami hazard posed by distant great earthquakes, Rapa Nui (Easter Island), in Southeast Pacific Ocean, is exposed frequent and intense coastal storms. Here, we use sea-level records field surveys guided video photographic footage show that extreme sea levels at occur much more than previously thought thus constitute an unrecognized inland’s maritime supply chain. We found e...

The basic theory of dynamic tides in close binaries is reviewed. Particular attention is paid to resonances between dynamic tides and free oscillation modes and to the role of the apsidal-motion rate in probing the internal structure of binary components. The discussed effects are generally applicable to stars across the entire Hertzsprung-Russell diagram, including the binary OB-stars discusse...

Today’s information technology departments have widely varying demands for resources due to unexpected surges in subscriber demands (e.g., a large response to a product promotion). Further complicating matters is that many resource actions done in response to surges (e.g., provisioning or de-provisioning an application server) have substantial delays (lead times) between initiating the resource...

The equilibrium tide-generating forces in the lunar orbital plane of a planet of radius R are calculated for the case of N moons of mass Mi orbiting the planet at instantaneous polar coordinates (Di, αi). For the case of a single moon, there are only two high tides. For the case of two moons, it is found that there can exist a critical lunar orbital distance at which two high tides become unsta...

Gravitational tides are widely understood to strip and destroy galactic substructures. In the course of a galaxy merger, however, transient totally compressive tides may develop and prevent star forming regions from dissolving, after they condensed to form clusters of stars. We study the statistics of such compressive modes in an Nbody model of the galaxy merger NGC 4038/39 (the Antennae) and s...
