A high coefficient of permeability indicates that water can flow easily through the soil, which is critical for drainage and stability considerations.

Sieve analysis is used to classify soil based on the distribution of particle sizes, which is essential for understanding its behavior and suitability for various engineering applications.

The Proctor test is used to determine the compaction characteristics of soil, which is essential for ensuring adequate strength and stability in construction.

The angle of internal friction for sandy soils typically ranges from 30° to 45°, which is important for assessing shear strength.

Soil boring is a common method used in site investigations to obtain samples and assess the properties of the subsurface soil.

The liquid limit test is used to determine the Atterberg limits, which help classify fine-grained soils based on their plasticity.
