Germany 69 15 71 Abstract 17 73 Reconstruction of coastal development, environment and settlement history is one of the main objectives of coastal archaeology 19 in Schleswig–Holstein. The fieldwork program concentrated until 1975 on the excavation of dwelling mounds, and after that on the 75 reconstruction of the landscape and settlement history of large areas. Cultural elements of the coastal area were mapped in several surveys integrating archaeological, geological andpalaeobotanical aspects on the islandof Sylt (Archsum project), in the North 21 77 Frisian tidal flats (Norderhever project), on the Eiderstedt penisula, and in Dithmarschen. According to this kind of research, environmental changes dominated the settlement history and settlement pattern in the 1st 23 millennium AD. Archaeological finds and excavations indicate that the earliest coastal settlements were founded in the salt marshes 79 of Schleswig–Holstein in the early Roman period. In Dithmarschen as well as in the southern part of Eiderstedt the river marshes 25 and salt marshes were densely populated during this period. In the 1st and 2nd century AD the inhabitation of the area took place in 81 a phase of lowering of the sea level. The settlements were erectedon the natural surface of the coastal marshland,preferably on 27 elevated areas. Thereafter, a rising sea level and intensified flooding led to the abandonment of some settlements. At other localities 83 the inhabitants protected themselves against the storm surges by the construction of dwelling mounds, so-called Wurten. The first 29 phase of inhabitation of the coastal marshlandendedatabout AD 450. A secondphase of inhabitation of the coastal marshes began 85 in the middle or late 7th century AD. It started with new settlements on the natural land surface of the marshland and was followed 31 by as secondphase of Wurt construction. 87 The present-day North Frisian tidal flat area was covered with extended peat bogs and could not be inhabited before high Medieval times. Starting with this period the natural landscape changed to a cultural landscape. Cooperatives of peasants and the 33 parishes played an important role in this process. Dikes were built and deep seated areas were drained and cultivated. In the late 89 Middle Ages catastrophic storm floods had terrible effects: the sea destroyed large parts of the North Frisian Utlande. Remnants of 35 this periodlike Warften, dikes, field pattern, and churches, are still visible in the present-day tidal flats. The unfavourable 91 combination of human activities (peat cutting for salt production) and natural geological processes was responsible for the 37 catastrophic floods of late Medieval times. 93 Cultural monuments of this evolution are still preservedin the coastal landscape.The protection of the Cultural Heritage is of 39 high value for the future. 95 r 2003 Elsevier LtdandINQUA.
