چکیده

Starting from an asymptotic representation of the velocity potential at infinite distances, the radiation problem of water waves due to a line source in presence of a bottom having step deformation is studied. Relations connecting amplitudes of radiated waves at infinite distances are worked out using Green’s second identity. The general asymptotic forms of the potential form at infinite distances are written down in a discrete manner. A matrical representation connecting wave amplitudes is arrived at.

Constriction Scour In Pressurized Flow Condition (RESEARCH NOTE)

When depth of flow past a river bridge exceeds opening under the bridge, the flow under the bridge becomes pressurized. The water is directed downward and under the bridge deck, causing increase in velocity and shear stress on the bed thereby increasing bed scour. This is termed as Pressure Flow Scour. The present study investigates the phenomenon of pressure flow scour resulting from a submerg...

Quasi-Static Deformation of a Uniform Thermoelastic Half –Space Due to Seismic Sources and Heat Source

This paper investigates the quasi-static plane deformation of an isotropic thermoelastic half-space due to buried seismic sources and heat source. Governing equations of thermo-elasticity are solved to obtain solutions for seismic sources in a thermoelastic half-space. The general solutions are acquired with the aid of Laplace and Fourier transforms and with the use of boundary conditions. The ...
