Source and mouth of the Broye

The Broye ([ bʀwa ]; Friborg patois Brouye ^{? / I} , mentioned as Brodiam as early as 1155 ) is a 89 km long river in the western Swiss plateau with a catchment area of ​​around 850 km² and an average water flow of a good 12 m³ / s. The German name Brüw is no longer used even in German-speaking Switzerland. On the other hand, the pronunciation [ ˈbro () jə ] has become common here.

geography

course

Several small spring streams on the western slope of the Niremont and the Alpettes in the Freiburg Pre-Alps south-west of Bulle unite at Semsales to form the Broye. This flows first to the southwest parallel to the foothills of the Alps, but then changes direction after about 10 km abruptly to the north into the Swiss plateau. Between Oron-la-Ville and Moudon , it runs first in an open valley into which it has dug like a gorge south of Moudon. At Moudon the general direction of flow changes again, this time to the northeast. Between Moudon and Payerne , the Broye uses a valley carved out by the Ice Age Rhone glacier with a wide, flat valley floor and steep, e.g. T. rocky slopes.

At Payerne the Broyetal opens up into a wide, up to 5 km wide valley depression with intensive agricultural use. Shortly before its confluence with the Murten lake , the Broye takes on its longest tributary, the Petite Glâne , from the left . The Broye leaves Lake Murten at its northeast corner. Then it runs in a canal bed from the Jura water correction around Mont Vully to the west into Lake Neuchâtel . This last section between Lake Murten and Lake Neuchâtel is also called Broyekanal (French: Canal de la Broye ). A canal with a similar course was already used by the Romans, among other things for long-distance trade and for the procurement of materials for the construction of Aventicum (quarries in the Jura ). Further tributaries are the Carrouge and Lembe from the left and the Arbogne from the right .

Only in the upper reaches of the Broye still has near-natural banks, below Moudon it was canalized and straightened as a result of numerous floods in the flat valley floor in the 19th and early 20th centuries.
