Compaction and consolidation | SpringerLink

Gravitational compaction and consolidation factors are briefly reviewed and discussed in relation to subsidence and estimating sea level. Most coastal Holocene regions show uneven subsidence, this being controlled by variability in the thickness, lithofacies and diagenetic and burial history of the successions. Tectonism is also influential.

Soil compaction | UMN Extension

What is compaction? Soil compaction occurs when soil particles are pressed together, reducing pore space between them (Figure 1). Heavily compacted soils contain few large pores, less total pore volume and, consequently, a greater density. A compacted soil has a reduced rate of both water infiltration and drainage. This happens because large pores more effectively move water downward through ...

Terminology has to be used in the right way : when air is squeezed out of a soil, natural or engineered, the right word is compaction. When water is squeezed out, then it's consolidation. Consolidation is generally not associated to engineered fills constructed in layers above groundwater table, and are generally made of granular materials.
