Modelling The Effect of Hydraulic Conductivity on One Dimensional Contaminant Transport in RBF System

Riverbank filtration (RBF) system is a surface water technology that is basedon the natural treatment of filtration instead of the use of chemicals, to pre-treat sur-face water and provides public water supplies. Hydraulic cond...
