Asymptotic behavior of tidal damping in alluvial estuaries

[1] Tidal wave propagation can be described analytically by a set of four implicit equations, i.e., the phase lag equation, the scaling equation, the damping equation, and the celerity equation. It is demonstrated that this system of equations has an asymptotic solution for an infinite channel, reflecting the balance between friction and channel convergence. Subsequently, explicit expressions f...

Nonlinear Damping of Oscillations in Tidal-Capture Binaries

We calculate the damping of quadrupole fand low order g-modes (primary modes) by nonlinear coupling to other modes of the star. Primary modes destabilize high degree g-modes of half their frequency (daughter modes) by 3-mode coupling in radiative zones. For sunlike stars, the growth time ≡ η ≈ 4E −1/2 0,42 days, where E0,42 is the initial energy of the primary mode in units of 10 erg, and the n...

Resonant Oscillations and Tidal Heating in Coalescing Binary Neutron Stars

Tidal interaction in a coalescing neutron star binary can resonantly excite the g-mode oscillations of the neutron star when the frequency of the tidal driving force equals the intrinsic g-mode frequencies. We study the g-mode oscillations of cold neutron stars using recent microscopic nuclear equations of state, where we determine self-consistently the sound speed and Brunt-Väisälä frequency i...

Clay Minerals as Indicators of Sediment Source in Tidal Estuaries of Long Island Sound

-Clay minerals were used as indicators for determining the source of sediment in recently dredged harbors along the north shore of Long Island Sound. Amount and characteristics of clay minerals in sediments from the dredged channels were compared to their amount and characteristics in the surrounding soils and in sediments from Long Island Sound. Clay minerals in sediments from the channels wer...
