The Rhine is one of the major European rivers, which has its sources in Switzerland and flows in an mostly northerly direction through Germany and The Netherlands to the North Sea. The river begins in the Swiss canton of Graubünden in the southeastern Swiss Alps, forms part of the Swiss-Liechtenstein, Swiss-Austrian, Swiss-German and then the Franco-German border, then flows through the German Rhineland and the Netherlands and eventually empties into the North Sea.
The Rhineland is the name used for a loosely defined area of Western Germany along the Rhine, chiefly its middle section.
The Ruhr is a polycentric urban area in North Rhine-Westphalia, Germany. With a population density of 2,800/km2 and a population of over 5 million (2017), it is the largest urban area in Germany and the third-largest in the European Union. It consists of several large cities bordered by the rivers Ruhr to the south, Rhine to the west, and Lippe to the north. In the southwest it borders the Bergisches Land. It is considered part of the larger Rhine-Ruhr metropolitan region of more than 12 million people, which is among the largest in Europe.
The Rheinisch-Bergische Kreis is a Kreis (district) in the Cologne Bonn Region of North Rhine-Westphalia, Germany. Neighboringdistricts are Oberbergischer Kreis and Rhein-Sieg, and the district-free cities Cologne, Leverkusen, Solingen and Remscheid.
The Dissected Till Plains are physiographic sections of the Central Lowlands province, which in turn is part of the Interior Plains physiographic division of the United States, located in southern and western Iowa, northeastern Kansas, the southwestern corner of Minnesota, northern Missouri, eastern Nebraska, and southeastern South Dakota.
The European Plain or Great European Plain is a plain in Europe and is a major feature of one of four major topographical units of Europe - the Central and Interior Lowlands. It is the largest mountain-free landform in Europe, although a number of highlands are identified within it.
The North German Plain or Northern Lowland is one of the major geographical regions of Germany. It is the German part of the North European Plain. The region is bounded by the coasts of the North Sea and the Baltic Sea to the north and Germany's Central Uplands to the south.
This division of Germany into major natural regions takes account primarily of geomorphological, geological, hydrological, and pedological criteria in order to divide the country into large, physical units with a common geographical basis. Political boundaries play no part in this, apart from defining the national border.
The Westphalian Lowland, also known as the Westphalian Basin is a flat landscape that mainly lies within the German region of Westphalia, although small areas also fall within North Rhine and in Lower Saxony. Together with the neighbouring Lower Rhine Plain to the west, it represents the second most southerly region of the North German Plain, after the Cologne Bight. It is variously known in German as the Westfälische Bucht, the Münsterländer or Westfälische Tieflands- or Flachlandsbucht.
The West Hesse Depression is part of the West Hesse Highlands and Lowlands region in the north of the German state of Hesse. Like the East Hesse Depression, it is a series of separate depressions that form a natural corridor and have been an important historical trade route.
The Gäu Plateaus form the largest natural region in the German state of Baden-Württemberg. Not surprisingly, the individual geographical units of this large region show considerable variations in climate and soil types. A common feature of the region, however, is its landscape of flat-topped hills of Muschelkalk, gently rolling tracts of loess and plateaus in which the layers of Muschelkalk have been covered by sediments of Gipskeuper and Lettenkeuper.
The Weser Depression or Weser Lowlands is the region north of Porta Westfalica in Germany, where the River Weser no longer flows through a valley, but a broad plain consisting of meadows and river terraces.
The Dümme Geest Lowland is a natural region unit of the 3rd level in northwest Germany that mainly extends over southwestern Lower Saxony with a small area over the border in North Rhine-Westphalia. Its uniqueness consists in the very varied juxtaposition of different landscape elements of the Northern Lowlands of which the Dümmer Geest Lowland is a part.
The Lower Germanic Limes is the former frontier between the Roman province of Germania inferior and Germania Magna. The Lower Germanic Limes separated that part of the Rhineland left of the Rhine as well as the Netherlands, which was part of the Roman Empire, from the less tightly controlled regions east of the Rhine.
The Jülich-Zülpich Börde is a landscape in the Rhineland in the German state of North Rhine-Westphalia on the northern edge of the Eifel. It forms the western part of the Lower Rhine Bay, west of the Rhine, excluding the actual Cologne Lowland, from which it is separated by the ridge of the Ville. It is divided into the Jülich Börde around the town of Jülich in the north and the Zülpich Börde around the town of Zülpich in the south, the two areas being separated from one another by the Bürge forest. Both parts are natural region major units of the Lower Rhine Bay.
The Middle Rhine Basin is the central landscape region of the Middle Rhine in Germany and, along with the Limburg Basin, forms one of the biggest intra-montane lowland regions within the Rhenish Massif. The basin is divided into the valley bottom of the Neuwied Basin, the Neuwied Basin Perimeter east of the Rhine and the Lower Moselle Valley west of the Rhine in the south, and the Maifeld-Pellenz Hills in the north.
The Limburg Basin is one of the two large intramontane lowland areas within the Rhenish Massif in Germany, the other being the Middle Rhine Basin. It forms the central part of the natural region of the Gießen-Koblenz Lahn Valley between the Weilburg Lahn Valley Region and the Lower Lahn Valley on both sides of the Lahn around the town of Limburg.
