Abstract: A model is presented for predicting the rate of longitudinal dispersion in nonhomogeneous oscillatory flows. The model consists of mathematical representations of velocity and salinity over a cross section and their ...

Abstract: Movement of volatile organic compounds (VOCs) through compacted clay liners was investigated using laboratory-scale column and tank tests. Hydraulic conductivity of the compacted clay was not significantly impacted by the ...

Abstract: A series of column and tank tests were conducted using bromide to estimate seepage velocity through compacted clays. Bromide concentrations in effluent and sectioned-core pore water were measured. The seepage velocity ...

Abstract: Scrap tire disposal is a problem of growing concern. One solution to this problem is innovative methods for the reuse and recycling of scrap tires. Based on batch isotherm tests, scrap tire chips have been identified to ...

Abstract: A quasi-two-dimensional partition-diffusion transport model was developed to determine the diffusion coefficient and partition coefficient for various types of geomembranes from measurements of aqueous organic compound ...

Abstract: The transient and steady-state mass fluxes were estimated based on partition and diffusion coefficients and compared with fluxes through holes in liner systems under representative field conditions. Stretched high-density ...

Abstract: Tire pyrolysis kinetics was investigated to explore an economically viable design for the pyrolysis process. Derivative thermogravimetry (DTG) and thermogravimetric analysis (TGA) were found to provide valuable information ...

Abstract: Batch sorption tests were conducted to investigate the sorption capacity of organic compounds by ground tire and to assess the effects of the presence of other organic compounds, ionic strength, pH, ground tire particle ...

Abstract: Water-transmission main (WTM) failures transporting a much greater volume of water cause flooding roads, the inconvenience of daily activities, and economic loss. However, few studies have investigated factors affecting ...
