so far, for an analysis of seepage under hydraulic structures much research has beenconducted in the form of numerical models. however, few field and laboratory workshave been performed to study the boiling phenomena for evaluating numerical models.throughout the present work, a laboratory model was built to simulate seepage and itscontrolling measures under sheet piles. the model consisted of ...

We present an experimental approach for investigating the potential for bioremediation of Ž . volatile organic compounds VOCs in fractured rock vadose zones. The experimental work was performed with rock samples and indigenous microorganisms from the site of the United States Ž . Department of Energy’s Idaho National Engineering and Environmental Laboratory INEEL , located in a basalt flow basi...

Numerical models can be valuable tools in the prediction of seepage. The results can often be misleading if proper variational analysis is not performed. Measurement of the soil-water characteristic curve (SWCC) or saturated and unsaturated hydraulic conductivity information is often neglected or minimized. The modeller is therefore forced to develop a seepage model based on estimated soil prop...

Remote sensing has been a key tool for ocean slicks monitoring and new discoveries based on offshore seepage detection. In this context, this contribution has a two-fold objective. Firstly, in order to spectrally characterize hydrocarbons (HCs), we conducted VNIR-SWIR-TIR spectral measurements of petroleum samples yielded from large, off-shore oil fields sited at sedimentary basins of Brazil. S...

relief wells are used extensively to relieve excess hydrostatic pressure in pervious foundation strata overlain by impervious top strata, conditions which often exist landward of levees and downstream of dams and hydraulic structures. placing well outlets in below-surface trenches or collector pipes helps dry up seepage areas downstream of levees and dams. relief wells are often used in combina...

In order to obtain a reasonable extraction drilling method for coal seam working faces and carry out targeted as well cost-effective hole placement optimization, gas–solid coupled model based on the rock deformation field matrix–fissure dual seepage–diffusion was established numerically solved via use of COMSOL Multiphysics finite element software optimize gas transport parameters Dongpang mine...

The clarification on the collapse mechanism of a caisson breakwater has been an urgent task in order to reduce damages caused by next millennium tsunamis. In this study, piping destruction of a mound induced by seepage flow is taken into consideration solely. A stabilized ISPH method proposed by Asai (2012) is adopted with some modification associated with the extended Darcy law (Akbari 2013, 2...
