The Plessur is a river, 33 km (21 mi) long, and a right tributary of the Rhine running through the Swiss canton of Graubünden. Its head is near Arosa in the Plessur Range. It then flows through the Schanfigg valley before emptying into the Rhine at Chur.
A tributary or affluent is a stream or river that flows into a larger stream or main stem river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean.
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, emptying into 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.
Arosa is a statistic town and a municipality in the Plessur Region in the canton of Graubünden in Switzerland. It is both a summer and a winter tourist resort.
The Langwieser Viaduct, an early reinforced concrete railway bridge constructed in 1914, spans the Plessur near Langwies.
The Langwieser Viaduct is a single track reinforced concrete railway bridge spanning the Plessur River and the Sapünerbach, near Langwies, in the Canton of Graubünden, Switzerland.
Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (rebar) and is usually embedded passively in the concrete before the concrete sets. Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of steel, polymers or alternate composite material in conjunction with rebar or not. Reinforced concrete may also be permanently stressed, so as to improve the behaviour of the final structure under working loads. In the United States, the most common methods of doing this are known as pre-tensioning and post-tensioning.
Its main tributaries include the Rabiosa, the Welschtobelbach, Sapünerbach and Fondeierbach.
The Rabiosa, also called the Rabiusa or, on in the municipality of Malix, the Landwasser (Alemannic), is a 7.9-kilometre-long, left-hand tributary of the Plessur in the Swiss Canton of Grisons.

The Aare or Aar is a tributary of the High Rhine and the longest river that both rises and ends entirely within Switzerland.
The river IJssel, sometimes called Gelderse IJssel to avoid confusion with the Hollandse IJssel, is the branch of the Rhine in the Dutch provinces of Gelderland and Overijssel. The Romans knew the river as Isala. The IJssel flows from Westervoort, east of the city of Arnhem, until it discharges into the IJsselmeer. The River IJssel is one of the three major distributary branches into which the Rhine divides shortly after crossing the German-Dutch border.
The Erft is a river in North Rhine-Westphalia, Germany. It flows through the foothills of the Eifel, and joins the Lower Rhine. Its origin is near Nettersheim, and its mouth in Neuss-Grimlinghausen south of the Josef Cardinal Frings Bridge. The river is 106.6 kilometres (66.2 mi) long, which is significantly shorter than it was originally. Due to the open-pit mining of lignite in the Hambacher Loch, the flow of the river had to be changed.
The Alpine Rhine Valley is a glacial alpine valley, formed by the part of the Alpine Rhine between the confluence of the Anterior Rhine and Posterior Rhine at Reichenau and the Alpine Rhine's mouth at Lake Constance. It covers three countries and the full length of the Apine Rhine is 93.5 km.
The Lahn is a 245.6-kilometer (152.6 mi)-long, right tributary of the Rhine in Germany. Its course passes through the federal states of North Rhine-Westphalia (23.0 km), Hesse (165.6 km), and Rhineland-Palatinate (57.0 km).
The Ill is a river in Alsace, in north-eastern France. It is a left bank, or western, tributary of the Rhine.
Ahr is a river in Germany, a left tributary of the Rhine. Its source is at an elevation of approximately 470 metres (1,540 ft) above sea level in Blankenheim in the Eifel, in the cellar of a timber-frame house near the castle of Blankenheim. After 18 kilometres (11 mi) it crosses from North Rhine-Westphalia into Rhineland-Palatinate.
The Oude IJssel or Issel is a river in Germany and the Netherlands approximately 82 km (51 mi) long. It is a right tributary of the river IJssel. Oude IJssel is Dutch for "Old IJssel"; the Oude IJssel was the upper course of the IJssel until the connection with the Rhine was dug, possibly in the Roman era.
The Plessur Alps are a mountain range in the Alps of eastern Switzerland. They are considered to be part of the Western Rhaetian Alps. They are named after the river Plessur, which originates from the center of the ranges. The Plessur Alps are separated from the Glarus Alps in the west by the Rhine valley; from the Rätikon range in the north by the Landquart river valley (Prättigau); from the Albula Alps in the south-east by the Landwasser river valley; from the Oberhalbstein Alps in the south by the Albula river valley.
The Wied is a river in Rhineland-Palatinate, Germany, and a right tributary of the Rhine.
The Sauer is a river in France (Alsace) and Germany (Rhineland-Palatinate). A left tributary of the river Rhine, its total length is about 70 kilometres (43 mi). Its upper course, in Germany, is called Saarbach. Its source is in the Palatinate forest, near the French border, south of Pirmasens. It flows into France near Schœnau, and continues through Wœrth and north of Haguenau. It flows into the Rhine in Seltz, opposite the mouth of the Murg.
The Elz is a river in Baden-Württemberg, Germany, a right tributary of the Rhine. It rises in the Black Forest, near the source of the Breg. The Elz flows through Elzach, Waldkirch and Emmendingen before reaching the Rhine near Lahr. Its length is approx. 121 km (75 mi).

The Lauter is a river in Germany and France.
The Hinterrhein is one of the two initial tributaries of the Rhine in the canton of Graubünden in Switzerland, flowing from the village Hinterrhein near the San Bernardino Pass through the Rheinwald valley into a gorge called Roflaschlucht. In this gorge an equally sized tributary, the Avers Rhine, adds waters from the deep Val Ferrera and the very remote alp Avers and its side valley Valle di Lei on Italian territory. After the Rofla Gorge, the valley widens into a section called Schams. The Hinterrhein then reaches Andeer, before passing through another gorge, Viamala just before Thusis. Now another tributary of slightly bigger volume reaches the Hinterrhein as the Landwasser, draining a system of valleys, which is commonly known as Davos joins via the Albula coming from the Albula Pass, which is also the name of a railway line that has become a UNESCO world heritage. Another big tributary of Albula river is Gelgia from the Julier pass area. After flowing to Rothenbrunnen through a valley called Domleschg with an incredible number of castles again the river is left alone from civilisation in the floodplain Isla Bella near Rhäzüns, before it joins the Anterior Rhine at Reichenau, all of them also in Graubünden.
The Kraichbach is a 60 km long right tributary of the Rhine River running through the German state of Baden-Württemberg. Its source is in the Kraichgau region near the municipality of Sternenfels. The brook then flows to the northwest through Kürnbach, Oberderdingen, Kraichtal, Ubstadt-Weiher, Bad Schönborn and Kronau, all in the district of Karlsruhe. It then enters the district of Rhein-Neckar-Kreis and flows through Sankt Leon-Rot, Reilingen, Hockenheim and Ketsch before joining the Rhine.
The Alb is a river in the Northern Black Forest in Germany. It is a tributary of the Rhine, and flows through the cities of Karlsruhe, Ettlingen and Bad Herrenalb.
The Rein da Curnera is a right tributary of the Anterior Rhine and one of the main tributaries of the Rhine. It is fed from multiple sources and glaciers at the southern end of the valley. The river is about 8 kilometres (5 mi) long and flows north through the Val Curnera. Approximately in the middle of its route, a dam was constructed by Kraftwerke Vorderrhein AG, which formed Lai da Curnera. At this point, the Rein da Curnera takes up a left tributary, the Rein da Maighels.
