Suction–Water Content Relationship for Hill Soil of North-East India

Malaya, C. / Sreedeep, S.

Abstract Hill-slopes of north-east (NE) India mainly constitute of unsaturated red soil. While analyzing the stability of hill-slope, hydrology, i.e., infiltration and surface drainage becomes indispensable. Defining this suction–water content relationship (SWR) of the soil is important. It is generally expressed in terms of a graphical relationship between soil suction and water content (or saturation). SWR of red soil has been obtained using equitensiometer, relative humidity sensor, and volumetric water content sensor. From the measured SWR, its parameters were defined. The parameters defining this SWR are key input for analyzing hill-slope hydrology and stability. The details of the methodology adopted in this study are presented in this paper.
