Valley infills are essential for understanding changes in hydrology and landscape. Anthropogenic activities are proven by prehistoric settlement remains, which mark distinct sediments and soils as usable land during certain time periods. In 2009 and 2018/19, excavations by the Saxonian Archaeological Heritage Office were conducted in the Elbe valley between Meißen and Dresden, preceding the construction of two natural gas pipelines. As a result, two important multicultural prehistoric sites were discovered on the Lower Weichselian Terrace (LWT) in different sediments and on varying stratigraphic levels. During this study sediments and soils at the excavation sites and throughout the pipe trench have been documented. Micromorphological, sedimentological and geochemical investigations and analyses of archaeobotanical and archaeological finds, complemented by 14C and optically stimulated luminescence (OSL) dating, enabled deciphering the structure of sediments and soils. Two major sites were the focus. At the Clieben site, an early Neolithic settlement and former topsoil, developed in a Weichselian valley loam above gravels and sands, are covered by younger overbank fines. At the Brockwitz site, shallow incision channels in the LWT were filled with clayey overbank fines during the Preboreal. An overprinting humic soil horizon was later anthropogenically overprinted during the early and middle Neolithic period. An omnipresent layer of Subboreal or younger overbank fines, covering the majority of the LWT in combination with the spatially confined Preboreal overbank fines, mirrors the ever-growing risk of flooding in a formerly attractive settlement area.
