Soil Identification by Visual-Manual Methods

John Huang, Ph.D., PE and John Poullain, PE

This two hour online course discusses methods for the identification and description of soils based on visual and manual examinations. The methods are used not only for soil identification in the field but also in the lab or office. The equipment is minimalized to items such as a pocket knife, magnifying glass, scale and some hydrochloric acid. Values determined by visual-manual methods are approximate and have subtle differences from lab classifications. However they are meaningful and good indications of existing soil properties.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
