  3. Digging - Wikipedia

    en.wikipedia.org/wiki/Digging

    An excavation lake (also a flooded gravel pit) is an artificial lake, which usually has its origins in the excavation of gravel or sand for construction materials or in some other kind of surface mining. In many cases, the excavation holes are landscaped according to the land restoration required by law.

  4. Geotechnical engineering - Wikipedia

    en.wikipedia.org/wiki/Geotechnical_engineering

    Geotechnical engineering, also known as geotechnics, is the branch of civil engineering concerned with the engineering behavior of earth materials. It uses the principles of soil mechanics and rock mechanics to solve its engineering problems.
