Prolific natural hydrocarbon seepage occurs offshore of Coal Oil Point in the Santa Barbara Channel, California. Within the water column above submarine vents, plumes of hydrocarbon gas bubbles act as acoustic scattering targets. Using 3.5 kHz sonar data, seep distribution offshore of Coal Oil Point was mapped for August 1996, July 1995, and July 1973. Comparison of the seep distributions over ...

In this article, the problem of laminar, isothermal, incompressible and viscous flow in a rectangular domain bounded by two moving porous walls which enable the fluid to enter or exit during successive expansions or contractions is solved analytically by using the differential transform method (DTM). Graphical results are presented to investigate the influence of the non-dimensional wall dilati...

The action of water waves moving over a porous seabed drives a seepage ̄ux into and out of the marine sediments. The volume of ̄uid exchange per wave cycle may a€ect the rate of contaminant transport in the sediments. In this paper, the dynamic response of the seabed to ocean waves is treated analytically on the basis of poro-elastic theory applied to a porous seabed. The seabed is modelled as ...

In anti-seepage engineering, quality control and engineering applications are based on the accurate measurement of seepage indices for low-permeability materials. The test used to determine materials adopts an external source produce water pressure, flux produced during process requires manual measurement; thus, apparatus is complex difficult operate, thereby lowering testing efficiency restric...

Abstract Water inrush is one of the most dangerous disasters in coal mining. Due to large-scale mining and complicated hydrogeological conditions, thousands deaths huge economic losses have been caused by water China. There are two main factors determining occurrence inrush: source water-conducting pathway. Research on formation mechanism pathway direction prevent control inrush, seepage rock m...
