Conversion of the Modified Kovács Model Parameters to the Brooks & Corey and Van Genuchten Model Parameters for Granular Soils
The modified Kovács (MK) model can be considered as one of the most versatile predictive models available to estimate the unsaturated hydraulic functions. The MK model relies on basic geotechnical properties to obtain the water retention curve (WRC), which can then be used to define the relative permeability function. In addition, the model can also take into consideration hysteresis effects an...

مقایسه ویژگیهای هیدرولیکی آب و نفت خام در خاک
In order to assess hydraulics of LNAPLs in soil, the soil retention curves of petroleum and water were both determined through hanging column method. And, the hydraulic conductivity of petroleum and water were determined by steady head method. The water and petroleum hydraulic conductivities were 7.27 and 57.84 cm.day-1, respectively. The soil retention parameters were obtained based on van Gen...
متن کاملStochastic analysis of steady-state unsaturated flow in heterogeneous media: Comparison of the Brooks-Corey and Gardner-Russo models
Existing stochastic models of unsaturated flow and transport are usually developed using the simple Gardner-Russo constitutive relationship though it is generally accepted that the more complex van Genuchten and Brooks-Corey relationships may perform better in describing experimental data. In this paper, we develop first-order stochastic models for gravity-dominated flow in second-order station...
متن کاملSPE 89429 Theoretical Development of the Brooks-Corey Capillary Pressure Model from Fractal Modeling of Porous Media
The capillary pressure model proposed empirically by Brooks and Corey has been used widely for several decades. However it is not clear why the Brooks-Corey capillary pressure model works so well. In this study, it has been found that the empirical Brooks-Corey capillary pressure model can be derived theoretically from fractal modeling of porous media. Also found was the correlation between the...
