ABSTRACT
The concept of the flow net is based on Laplace’s equation of continuity, which describes the steady flow condition for a given point in the soil mass. This chapter describes Laplace’s equation of continuity and study its applications as related to problems such as the flow under hydraulic structures and seepage through earth dams. The case of constructing flow nets for seepage through soils that show anisotropy with respect to permeability. The seepage water flows from a soil with relatively fine grains into a coarser material, there is a danger that the fine soil particles may wash away into the coarse material. Over a period of time, this process may clog the void spaces in the coarser material. The several solutions have been proposed for determination of the quantity of seepage through a homogeneous earth dam.
