Effect of Faults and Fractures on Springwater Quality and Discharge of West Phaileng, Mizoram

Abstract

The North Eastern part of India comprise of hilly slopes and ridges, where the main water sources are rivers, streams and springs. Many springwater sources have been reported drying up recently. A lithology shows the area to consist of clay, silt, shale, siltstone and sandstone where porosity is limited. The hydrochemistry suggested immature and relatively young with weathering of phyllosilicate mineral governing them. Dual flow hydrodynamic of govern the recharge hydrograph with initial rapid recharge through conduit flow followed by slower diffused flow through pores. The conservation measures by recharge pit, bunds and checkdams is the most viable option.
