The development history of sand dams all over the world is related to the management of barren streams. As early as the14th century, countries in the European Alps built sand dams to trap the solid materials in the debris flow in the barren stream, so as to ensure the safety of buildings and facilities such as villages, roads and churches located on the alluvial fans of the barren stream. At that time, limited by technical and economic conditions, simple log sand dams, wooden frame stone sand dams, dry masonry sand dams and steel wire gabion sand dams were mainly built of trees or stones. With the development of water conservancy science and civil construction science, new dam types have emerged, such as orifice sand dam, slit sand dam, grid sand dam, grid sand dam and metal cable sand dam. Japan began to build sand bars in the17th century. In the practice of developing and utilizing land resources and soil and water conservation in mountainous areas, farmers in rocky mountainous areas in China have generally built a large number of dry masonry sand dams to intercept sediment and build agricultural land or orchards in ditches. In order to prevent debris (such as quartz sand) and soil sand from flooding the downstream farmland, farmers in the southern mountainous areas of China also built sand dams in ditches.
