| Abstract | ||||
| the present study investigates numerically the using of vertical sheet pile to control contaminant transport through different horizontal layered soil. Two finite element software SEEP/W and CTRAN/W are used to study the regional contaminated porous field numerically. The considered parameters are different depths of sheet pile, distance between sheet pile and point source of contamination, head between upstream and downstream of the sheet pile and coefficients of permeability for horizontal layered soils. The efficiency of the sheet pile is affected by arranging the horizontal layered soil and their hydraulic conductivity in the process of contaminant transport and treatment. The effective depth of vertical sheet pile with different permeability is evaluated by preparing dimensionless designed charts as a guide reference for improving the hydraulic performance of the remedial system. The results show that the arrival time increases for decreasing the head difference between upstream and downstream of the sheet pile and with increasing the coefficient of permeability of the lower layer. In addition, the effect of coefficient of permeability for the lower layer on the arrival time is dependent on any depth of sheet pile for large distance between the contamination point source and the sheet pile. Increasing the sheet pile depth has no effect on the elapsed arrival time for the higher permeability of the upper and the lower layer at any distance between the sheet pile and the contamination point source. The sheet pile must be deeply embedded in the lower layer to give a great effect on contamination transport for the value of the coefficient of permeability of the lower layer equal to or higher than 1×10-3 cm/sec because of being highly permeable. | ||||
