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...

The soil is a heterogeneous and anisotropic medium. Hydraulic conductivity, an intrinsic property of natural alluvial deposits varies both deterministically and randomly in space and has different values in various directions. In the present study, the permeability of natural deposits and its influence on the seepage flow through a natural alluvial deposit is studied. The 2D Finite Difference c...

This paper explored numerical techniques to simulate the movement of an applied tracer plume in a laboratory beach subjected to tide. The MARUN model (Boufadel et al., 1999) was used. The movement of the tracer plume in the beach and the development of a transient seepage on the beach surface were modeled. By calibrating the results of the numerical model against the observed data, the laborato...

In recent years, carbon dioxide capture and its geological storage (CCS) has been recognized as one of the most effective tools to mitigate climate change with its vast potential and cost effectiveness. With this background, many countries around the world have started to study on its technical aspects as well as economic aspects. In some countries, several commercial or experimental plants are...

An experimental investigation of multiple seepage-induced suffusion and its impact on the mechanical responses internally unstable gap-graded soil, with a fines content 25%, is presented in this paper. Using modified triaxial erosion apparatus, redesigned seepage control system, tests under conditions, as well undrained monotonic cyclic compression tests, are performed. It found that seepages c...
