| چکیده | ||
| In recent decades, attention to contamination propagation into soils and underground water has increased, which has led to a rise in the studies on soil contamination problems and methods of in-situ remediation. In this research, effective parameters on oil contamination propagation in soils and underground water have been investigated using FEM in order to determine propagation patterns. The main parameters are soil permeability, relative density of contamination and ground water table depth. Furthermore, the efficiency of pumping method as an in-situ remediation approach for contaminated soils has been examined. The results show there are different propagation patterns in coarse and fine grain soils and the higher efficiency of dual symmetric pumping approach for in-situ remediation. | ||
