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.

The hydraulic conductivity (K) of a homogeneous sandy clay mix aquifer is 2x10-3 cm/sec. The hydraulic gradient (groundwater surface slope) of the phreatic (water table) aquifer is 0.01 and the aquifer's effective porosity is 0.35. Calculate the average (advective) velocity of a conservative contaminant discharged to this groundwater unit. Enter your answer rounded to the nearest tenth in meters/year. Example: 5.2 , 65.7, 224.3 would all be proper forms of your answer.
