Abstract: Riverbank Filtration (RBF) is a managed surface-groundwater interaction process where surface water is induced to flow to pumping wells installed on the banks of rivers and lakes. We present the surface-groundwater interaction issues at various geomorphologic settings, from the headwaters of a river to its confluence with the oceans/lakes. In each reach, the factors for the sustainable operation of RBF systems are discussed. Siting of wells with respect to the river/lake, scouring and clogging of the river beds and the resulting impacts on pollutant removal, managing the wells during floods, and RBF at other settings have been addressed.

Keywords: riverbank filtration; bank filtration; well siting; river slope; morphology; river bed clogging; river bed scouring; groundwater flow; surface water; riverbanks; surface-groundwater interaction; pumping wells; rivers; lakes; pollutant removal; flooding; water pollution.
