Mohr: In 1871, he represented stress at a point graphically. It focuses on practical science rather than just the fundamentals or mathematical aspects of soil. The possibility of seepage of groundwater also needs to be considered while excavating the soil. He was the first one to introduce the concept of shearing resistance of the soil. Sometimes, subsoil water needs to be drained out to reduce the seepage forces. Atterberg: In 1911, he proposed that clay soil may exist in different stages of consistency, which depends on its water content. The void space between the particles may contain air, water or both. Particles of soil are filled loosely, creating a soil formation that consists of pore spaces. However, the extraction of pore water is simple in coarse grained soils since it moves freely within the region. Dams are a necessary part of todays infrastructure.
