The Upper Rhine Graben (URG) is a distinct geomorphic feature in SW Germany, with its southern part representing the border region with France. Being a large-scale endogenic morphostructure, the URG also hosts diverse exogenic fluvial and aeolian landforms, which well illustrates an interplay of endogenic tectonic and volcanic processes with climatically driven exogenic geomorphic processes. In recent centuries, anthropogenic activities such as gravel mining or river correction have come into play as an additional formative factor. The river Rhine as one of the largest rivers in Europe flows in south–north direction through the URG, dominantly controlling its sedimentary system and landforms such as fluvial terraces and dunes. In addition, thick alluvial deposits of the URG represent valuable sedimentary archives for reconstructing the geological, geomorphological, and environmental history of the URG. Furthermore, these graben fillings provide important aquifers as well as important sources for raw materials, e.g., gravel for the building industry. However, the URG is not only prominent from a geoscientific perspective, but due to its soils and favorable climatic conditions it is also intensively used for agriculture, including viticulture.

The Upper Rhine Graben: A Diverse Landscape Shaped by Endogenic and Exogenic Processes

摘要

The Upper Rhine Graben (URG) is a distinct geomorphic feature in SW Germany, with its southern part representing the border region with France. Being a large-scale endogenic morphostructure, the URG also hosts diverse exogenic fluvial and aeolian landforms, which well illustrates an interplay of endogenic tectonic and volcanic processes with climatically driven exogenic geomorphic processes. In recent centuries, anthropogenic activities such as gravel mining or river correction have come into play as an additional formative factor. The river Rhine as one of the largest rivers in Europe flows in south–north direction through the URG, dominantly controlling its sedimentary system and landforms such as fluvial terraces and dunes. In addition, thick alluvial deposits of the URG represent valuable sedimentary archives for reconstructing the geological, geomorphological, and environmental history of the URG. Furthermore, these graben fillings provide important aquifers as well as important sources for raw materials, e.g., gravel for the building industry. However, the URG is not only prominent from a geoscientific perspective, but due to its soils and favorable climatic conditions it is also intensively used for agriculture, including viticulture.
