Estimate the coefficient of permeability for uniform sand where a sieve analysis indicates that the D10 size is 0.15 mm (by Hazen formula). Also, the particle-size distribution curve for another sand indicates that the D15 size is 0.19 mm. If the sand deposit is in the dense or compact state, estimate the coefficient of permeability.

Soil Compaction Test

Soil compaction is the major area of geotechnical engineering. Soil is composed of multiple pores present on its surface, while the soil is mainly composed of gravel, sand, rocks, etc. The arrangement of these rocks and gravels is such that they build up voids (spaces) between them, which allows spaces for the roots of the plants and crops to spread and absorb the required amount of nutrients. Soil compaction is a major problem primarily caused by human activities, micro-organisms, and other multiple factors.
