Assessment of Sand and Gravel Potential and Silt and Clay ...
Units with high and moderate classifications have significant sand and gravel potential. For this project, mapped units with significant sand and gravel potential are typically associated with proglacial outwash and ice contact features. The quality of sand and gravel varies throughout the project area.
Soil porosity
Soil porosity (n) is the ratio of the volume of voids to the total volume of the soil: n = (V_v) / V. Where V_v is the volume of the voids (empty or filled with fluid), and V is the total volume of the soil. Porosity is usually used in parallel with soil void ratio (e), which is defined .

Unified Soil Classification System Wikipedia
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 classification system can be applied to most unconsolidated materials, and is represented by a twoletter symbol. Each letter is described below (with the exception of Pt):
Soil classification
Soil classificationis the separation of soil into classes or groups each having similar characteristics and potentially similar behaviour. A classification for engineering purposes should be based mainly on mechanical properties, permeability, stiffness, strength. The class to which a soil belongs can be used in its description.
