Fill dirt is taken from a location where soil is being removed as a part of leveling an area for construction; it may also contain sand, rocks, and stones, as well as earth. Fill dirt should be as free of organic matter as possible since organic matter will decompose creating pockets of empty space within the fill which could result in settling ...
The ability of the first fill layers to be properly compacted will depend on the condition of the natural material being covered. If unsuitable material is left in place and backfilled, it may compress over a long period under the weight of the earth fill, causing settlement cracks in the fill or in any structure supported by the fill.

There are various factors that affect soil temperature, such as water content, [84] soil color, [85] and relief (slope, orientation, and elevation), [86] and soil cover (shading and insulation), in addition to air temperature. [87] The color of the ground cover and its insulating properties have a strong influence on soil temperature. [88]
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil.The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol.
Soil compaction also impacts infiltration capacity. Compaction of soils results in decreased porosity within the soils, which decreases infiltration capacity. [4] Hydrophobic soils can develop after wildfires have happened, which can greatly diminish or completely prevent infiltration from occurring.

Typical curves of stress-difference as a function of strain in dense sands.. In soil mechanics, dilatancy or shear dilatancy [1] is the volume change observed in granular materials when they are subjected to shear deformations.
The first modern theoretical models for soil consolidation were proposed in the 1920s by Terzaghi and Fillunger, according to two substantially different approaches. [1] The former was based on diffusion equations in eulerian notation, whereas the latter considered the local Newton’s law for both liquid and solid phases, in which main variables, such as partial pressure, porosity, local ...
