In a liquid limit test relationship between water content (w) and number of blows required to close the groove (N) is obtained as w = 38.6066 - 4.0931n N. The plastic limit of the clay is 13%. Natural water content is 18%. Determine the liquid limit, plasticity index, liquidity index, relative consistency, flow index and toughness index of the soil. Also calculate activity number if percentage of clay is 36%.

Principles of Seepage

In hydrology, when water flows down in a pore or crack of unsaturated soil due to gravity, the deep layer of soil is called seepage. It is the slow movement of water in the soil layer. Seepage is mainly found near hydraulic structures and is responsible for the stability of earthen-type hydraulic structures.
