Investigation and Characterization of Soil for River Bank Filtration System

Abstract

. Soil study has been done to check soil suitability for River Bank Filtration (RBF). A Somlapura village on the bank of Tungabhadra River is selected as study site. In study site 3 different soil samples were collected from 3 different locations to understand the characteristics of soils at a river bank (i.e. Soil texture and permeability). The report of grain size analysis of these 3 samples showed that the soil consists of gravel and sand, which are porous in nature. The permeability test results of soil samples 1, 2, and 3are 1.16×10-3cm/sec, 7.67×10-3cm/sec, and 3.87×10-3cm/sec respectively. The maximum permeability of soil sample 2 at site 1 is 7.67×10-3 cm/sec. The soil which has the maximum permeability is more likely to be suitable for the River Bank Filtration ap-plication.
