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 ...

A fully penetrating cut-off wall is a vertical seepage barrier that penetrates an aquifer and embedded in underlying aquitard to certain depth. Groundwater with this type of occurs through three paths: leakage the body aquifer, aquitard, under wall. Seepage first path can be simply treated as one-dimensional flow. However, due mutual influence latter two paths, problem complicated still needs s...

Clay soil is a common building foundation material, and its permeability very important for the safety of pits later settlement buildings. However, traditional Kozeny-Carman (K-C) equation shows serious discrepancies when predicting clay in treatment. Therefore, solving application K-C problem faced by engineers scholars. In this paper, influence mineralogy on pore structure analyzed, then effe...

earth dam is a structure as homogeneous or non-homogeneous forms for raising water level or water supply. earth dam consist of different parts that one of the main parts is clay core. choosing an optimal non permeable core which causes reduction of seepage through dam body and also being stable is necessary. the objective of this research is to optimize the geometry of earth dam clay core such ...

In the present study, analytical solutions are obtained for two-dimensional advection dispersion equation for conservative solute transport in a semi-infinite heterogeneous porous medium with pulse type input point source of uniform nature. The change in dispersion parameter due to heterogeneity is considered as linear multiple of spatially dependent function and seepage velocity whereas seepag...

In this study, the 2D steady-state seepage analysis of dam body and its base is investigated using finite element method based on Galerkin’s approach. The foundation soil are considered as homogeneous isotropic anisotropic materials effects horizontal drainage length cutoff wall investigated. differential equation governing response water in obtained with help Darcy's law continuity equations. ...
