Abstract
The drinking water problem occurring during lean periods (March to July) in a city like Varanasi, India, situated on the crescent shaped concave bank of the Ganga can be minimized with a suitably placed river-bank filtration system. A laboratory model was constructed which showed that the phreatic line slope and the free seepage height played a vital role and the suitable site for the withdrawal of filtered water occurred in the outer half portion of the river. Its location should be situated away from the meandering zone with the least possibility of choking of soil pores. The diverging and converging pattern of streamlines of the city side bank defined the zone of stability, erosion and meandering.
