The specific aim of the study was to investigate how four adjacent geomorphological systems – a lake, a dune field, a small alluvial fan and a slope system – responded to the same impacts. Lake Tresssee is a shallow lake in the North of Germany (Schleswig-Holstein). During the Holocene, the lake’s water surface declined drastically, predominately as a consequence of human impact. The adjacent inland dune field shows several traces of former sand drift events. Using 30 new radiocarbon ages and the results of 16 OSL samples, this study aims to create a new timeline tracing the interaction between lake and dunes, as well, as how both the lake and the dunes reacted to environmental changes. The water level of the lake is presumed to have peaked during the period before the Younger Dryas (YD; start at 10.73 ka BC). After the Boreal period (OSL age 8050 ± 690 BC) the level must have undergone fluctuations triggered by climatic events and the first human influences. The last demonstrable high water level was during the Late Bronze Age (1003–844 cal. BC). The first to the 9th century AD saw slightly shrinking water levels, and more significant ones thereafter. In the 19th century, the lake area was artificially reduced to a minimum by the human population. In the dunes, a total of seven different phases of sand drift were demonstrated for the last 13,000 years. It is one of the most precisely dated inland-dune chronologies of Central Europe. The small alluvial fan took shape mainly between the 13th and 17th centuries AD. After 1700 cal. BC (Middle Bronze Age), and again during the sixth and seventh centuries AD, we find enhanced slope activity with the formation of Holocene colluvia.

该研究的具体目的是研究四个相邻的地貌系统（湖泊，沙丘场，小型冲积扇和斜坡系统）如何对相同的影响做出反应。Tresssee湖是德国北部（石勒苏益格-荷尔斯泰因州）的浅湖。全新世期间，湖水面急剧下降，主要原因是人为影响。相邻的内陆沙丘场显示出一些以前的沙丘漂移事件的痕迹。本研究使用30个新的放射性碳年龄和16个OSL样本的结果，旨在创建一条新的时间表来追踪湖泊和沙丘之间的相互作用，以及湖泊和沙丘对环境变化的反应。推测该湖的水位在Younger Dryas（YD；始于公元前10.73 ka）之前的时期达到峰值。在北方时期（OSL年龄为8050±690 BC）之后，水平面必须经历了由气候事件和第一批人为因素引起的波动。最后一个可证明的高水位是青铜时代晚期（公元前1003–844 cal）。公元前一世纪至九世纪，水位略有下降，此后更为明显。在19世纪，湖泊面积被人口人为地减少到最小。在沙丘中，过去13,000年共显示了七个不同阶段的沙丘漂移。它是中欧最精确的内陆沙丘年代学之一。小型冲积扇主要在公元13至17世纪形成。1700卡路里后 公元前（中世纪青铜时代），以及公元六，七世纪
