"Humanized River Systems“ – Influence of land use change and industry development on the morphdynamics of small rivers between uplands and lowlands: Examples from the Rur River catchment (Northrhine-Westfalia)

研究了鲁尔河流域人类活动引起的土地利用变化、不同产业的发展及其对河漫滩地貌动态的影响。鲁尔河全长165公里，集水面积2340平方公里，结合了高达600米的现有森林高地和高达200至30米的以农业为主的低地。与中欧大多数其他河流集水区一样，人类活动导致环境和河流形态发生变化。在鲁尔河流域，主要河流及其支流受到定居点、磨坊水坝、森林砍伐、采矿活动、工业污染物、建造水坝、重新造林和重新安置土地以及自然保护(如国家公园艾菲尔)的影响。该项目利用地球科学和工程方法，重点研究不同时期(如中世纪、现代、现在和未来)土地利用变化和其他人类活动对河流系统的影响。这包括测绘、采样、沉积学和地球化学分析、放射性碳和137Cs测年，以及河流和泛滥平原的数字模拟，包括大坝的影响。重点也是不同的人类影响以及高原和低地的自然河流动力。这种跨学科的方法将提供对鲁尔河流域以及从过去到现在和未来的人类影响的一个直观的了解。

Human induced landuse change and the development of different industries and their influence on the morphodynamic of river floodplains in the Rur River catchment are investigated. The Rur River stretches 165 km with a catchment size of 2340 km² and combines a nowadays-forested upland up to 600m with a lowland dominated by agriculture between 200 and 30 m NHN. As in most other river catchments of Central Europe, human activities caused changes in the environment and river morphology. In the Rur River catchment the main river and also its tributaries were influenced by enlargement of settlements, mill dams, deforestation, mining activities, pollutants by industries, construction of dams, re-forestation and relocation of land as well as natural conservation (e.g. National Park Eifel). This project focuses on the influence of land use change and other human activities on the fluvial systems in different times (e.g. Middle Ages, modern times, present and future) using geoscientific and engineering approaches and methods. This includes e.g. mapping, sampling, sedimentological and geochemical analysis, radiocarbon and 137Cs dating, and numeric modelling of rivers and floodplains including the influence of dams. Emphasis is also the different human impact as well as natural fluvial dynamics in the uplands and lowlands. The interdisciplinary approach shall provide a vison of the Rur River catchment and the human impact from the past to present and future.
