A technique that uses elastic waves to detect buried mines is being investigated. In the technique, an elastic wave is launched into the earth. It propagates and interacts with a buried mine causing displacements of both the mine and the surrounding soil. Because of the interactions of the wave with the mine, the soil surface displacements near the mine are quite different from those far from i...

River bed and bank protections should be designed regarding unsaturated soil conditions. Natural surface and pore water are not ideal incompressible fluids. Microscopic gas bubbles are dispersed in both of them. Due to the compressibility of such fluids delayed pore water reactions can be observed when external pressure changes act on such a medium. This paper deals with the results of laborato...
