Earthworks

Earthworks are artificial features formed by the deliberate shaping of the ground through excavation, deposition, or both. In civil engineering and land development, they include embankments, cuttings, dams, canals, terraces, and large mounds created to alter drainage, provide foundations, or accommodate transport routes. In archaeology and cultural landscape studies, earthworks refer to ancient and historic earth and stone formations such as ditches, banks, mounds, and hill forts that reveal past social and ritual practices.

Production and techniques: Earthworks are produced by moving soil, rock, and other materials, using manual labor or modern earthmoving equipment. Construction methods emphasize grading, compaction, and stabilization, as well as drainage to control moisture and settlement. In permanent landscapes, earthworks may be planted or faced with stones, turf, or vegetation to reduce erosion and improve appearance.

Functions and significance: They may serve defensive, territorial, ceremonial, or hydraulic purposes, or function as landscape design elements in parks and campuses. In archaeology, earthworks provide clues about labor organization, settlement patterns, and ritual practices, and they are often key factors in dating sites and understanding historical land use. Protection and management of earthworks face challenges from agriculture, development, and weathering.

Examples range from modern infrastructure projects such as road and rail embankments to prehistoric features like burial mounds and hill forts. The term encompasses a wide range of scales and purposes, reflecting the diverse ways humans shape the land.
