"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和不同工业的发展及其对河漫滩地貌动力的影响。鲁尔河绵延165公里，集水面积为2340平方公里，结合了海拔600米的森林高地和海拔200至30米的以农业为主的低地。与中欧的大多数其他河流集水区一样，人类活动造成了环境和河流形态的变化。在鲁尔河流域，主要河流及其支流受到以下因素的影响：扩大定居点、磨坊水坝、砍伐森林、采矿活动、工业污染、建造水坝、重新造林和土地迁移以及自然保护（例如，国家公园艾菲尔）。该项目的重点是利用地球科学和工程学的方法和手段，研究土地利用变化和其他人类活动在不同时期（如中世纪、现代、现在和未来）对河流系统的影响。这包括制图、取样、沉积学和地球化学分析、放射性碳和137Cs测年以及河流和洪泛区的数字建模，包括水坝的影响。重点也是不同的人类影响以及自然河流动力学在高地和低地。跨学科的方法将提供一个鲁尔河流域和人类的影响，从过去到现在和未来的愿景。

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.
