"Soil is a nonhomogeneous porous material consisting of three phases: solids, fluid (normally water), and air. Soil deformation may occur by change in stress, water content, soil mass, or temperature."^[1]

Settlement is a term typically used to describe the vertical movement of soil. The more generalized term is soil displacement which occurs as a result of the following conditions: Elastic Deformation, Consolidation, Secondary Compression and Creep, Dynamic Forces, Expansive Soil, Collapsible Soil.

Calculating Settlement for Static Loads

The total settlement, which is the response to stress applied to the soil, is comprised of three major components:

Immediate Settlement
Primary Consolidation Settlement
Secondary Compression Settlement

Measurement of Settlement

-Settlement, also referred to as ''consolidation'', is a natural mechanism of soil mechanics that occurs as a result of the dissipation of excess pore pressures and long-term creep of the soil. Due to both primary and secondary consolidation, both embankments as well as foundations comprised of compressible soils can experience varying degrees of settlement. While some settlement is expected after the construction of most dams, it is important that the amount of settlement is recorded and tracked in order to help detect any underlying problems in the embankment or foundation that could result from internal erosion or other hard-to-detect problems.
