Abstract The aim of this work is to assess the risk groundwater contamination associated with BTEX dissolution from fuels as a residual phase. Numerical simulations sixty scenarios were carried out software HYDRUS 2D/3D. Groundwater was analyzed given combination different porous media textures (silt loam, sandy loam and clay), water fluxes (0.5%, 1% or 3% Rainfall), table depths (1.5, 2.5, 5 8...

Knowledge of soil moisture dynamics in the unsaturated soil zone provides valuable information on the temporal and spatial variability of groundwater recharge. This is especially true for the Mediterranean region, where a substantial fraction of long-term groundwater recharge is expected to occur during high magnitude precipitation events of aboveaverage wet winters. To elucidate process unders...

Factors affecting preferential flow and transport in the vadose zone need to be investigated by experiments and simulations to protect groundwater against surface applied chemicals. The objectives of this study were to investigate the effects of several factors (soil structure, initial soil water content (SWC), and application rate) and their interactions on the extent of preferential flow and ...

Expansion of human activities causes dispersion of pollutants in the subsurface environment. The fate and movement of dissolved substances in soils and groundwater has generated considerable interest out of concern for the quality of the subsurface environment. Many analytical solutions for partial differential equations exist in soil science. Numerical solutions are more general, and often mor...

Abstract. Stony soils that have a considerable amount of rock fragments (RFs) are widespread around the world. However, experiments to determine effective soil hydraulic properties (SHPs) stony soils, i.e., water retention curve (WRC) and conductivity (HCC), challenging. Installation measurement devices sensors in these is difficult, data less reliable because their high local heterogeneity. Th...
