Aare river system

The Aare and its tributaries have two special features compared to the rest of the Rhine system :

They flow through numerous natural lakes.
Several of the bodies of water do not arise from a single source, but rather begin with an original glacier.

Outline of the course of the river

The course of the Aare essentially consists of three parts:

First of all, it is an alpine river that drains into two fjord lakes . The originally contiguous lake was divided by sediments from the Lütschine tributary . The catchment area of this alpine section of the Aare largely corresponds to the Bernese Oberland .
Then it flows northwest from the edge of the Alps to the foot of the Jura Mountains .
There they followed, as did their einmündender of West Creek, which consists predominantly of the Neuchâtel existing Zihl , the foot of the Jura . East of Brugg it turns north and flows through a wide Jura river to the Rhine.

Grouping the tributaries

The route from the Alps to the Swiss Plateau is similarly taken by its left tributary Saane and then the two large right tributaries Reuss (river) and Limmat , which reach the Aare close to each other at the foot of the Jura, 15 and 14 km respectively before its confluence with the Rhine . At 11,709 km², the catchment area of the Aare above the mouth of the Reuss is roughly the same as that of Lake Constance (11,487 km², discharge 78.4 km above the mouth of the Aare). Below the mouth of the Limmat, the mean discharge of the Aare is greater than that of the Rhine before the mouth of the Aare.

Of the tributaries of the Aare in the Swiss Plateau, the southwestern ones gather in the Zihl. The others flow almost parallel to each other and flow into the Aare between Lake Biel and the Reuss.

The major tributaries from the Jura are shaped by the peculiarities of these limestone mountains: the Orbe flows between its upper reaches in a valley bordered on both sides by the catchment area of the Rhone and the lower reaches through a sinkhole . The Areuse receives water from high valleys without surface drainage through two lateral karst springs . The Schüss rises in a karst area north of the Vue des Alpes pass and crosses various Jurassic clusters on its course. In the middle of its course, the Dünne river cuts a lump in the Jura rock and reaches the Mittelland near Oensingen .

River system board

The Aare, its main tributaries and their most important tributaries order upstream, lakes and glaciers as river sections
Representation: A body of water flows into that of the river courses listed above, the name of which begins above the indication of the confluence side ("right" / "left") of the flowing water. The position of each confluence is given in km from the next higher ranking, I (BS) is the zero point of the Swiss Rhine station in Basel, II the confluence of the Aare into the Rhine, etc. s. w. IIIS, IVS etc. are distances from the confluence with a lake. The distance from this mouth to the sea axis of the main body of water flowing through the lake is in the entry to the mouth after the +. Q-II and like. = flow path from the source to the mouth of a higher-ranking river. Q = distance between the mouth of a tributary and the source of the receiving water. The "length to the source" information in https://map.geo.admin.ch/ results in hydrological rivers that can be distributed over several GEWISS numbers. Where a river name appears several times due to lakes that have flown through it , the length information in the first line (or the one in the first line after the slash) refers to the entire course of the river, (the one before the slash and) the one in the following lines to sections. GEWISS numbers registered for glaciers refer, strictly speaking, to the (assumed) stream under the ice. It is generally shorter than the length of the glacier on the surface. Lengths of lakes refer to the valley path of the water flowing through or from the highest-ranking inflow to the highest-ranking outflow. Arrows point downstream and mark the upper parts of a previously mentioned river course. If both bodies of water arriving at a confluence are officially classified as source rivers of the body of water below, their mouths are marked with "↑ left" and "↑ right".
