Construction of Debris control structures have important role on the protection of watershed basins as well as aquiferous basins. It also had a great influence on preventing the movement of sediment deposits from upstream to downstream of these basins. Of these watershed basins, more attention should be given to GOLESTAN watershed province and its different basins. These types of watershed with special characters and high flood– water areas should also get special attention and precise planning. In such basins, varieties of deposits are transported from upstream to downstream. Since the residential areas and access roads are located on the flood–channels and downstream of these basins, remarkable damages are usually expected to take place on the infrastructures as well as on the installations (or industrial plants). Therefore, it is very important to control the movement of the upstream sediment deposits by reducing the slope of the existing channels or constructing sediment control structures as well as Debris control structures for trapping the debris and sediments. One example of these Debris control structures are the small earth dams at the height of 6–10 m that are built in different areas of GOLESTAN province.It is essential to construct earth dams with sediment control structures in the upstream channels of the basins due to the existence of high erodible soils in the region. Geologically, MALEK ALI TAPPEH basins are located in loess covered regions. Sinceloess soils are weak with high settlement potential, construction of structures should be carried out with special plan. Also due to the lack of suitable construction materials in the region as well as economic reasons for transporting these materials, the construction of the earth dams was carried out from the in situ materials in the region.<\div>
