Broye

The Broye at Moudon

The Broye ( [ bʀwa ]; Freiburg Patois Brouye / i, already in 1155, as mentioned Brodiam? ) Is a 72 km long river in the western Swiss Plateau with a catchment area of approximately 850 km ². The German name Brüw is no longer used today, even in German-speaking Switzerland. In contrast, here is the pronunciation [ bro ( ː ) jə ] naturalized.

Several small source streams on the western slope of the Niremont and Alpettes in the Fribourg Pre-Alps southwest of Bulle unite in Semsales to Broye. These first flows parallel to the foothills chains to the southwest, the direction then changes about 10 km but abruptly northward into the Swiss Plateau. Between Oron- la -Ville and Moudon it runs first in an open valley floor, in which it has carved a gorge south of Moudon. In Moudon the general flow direction changes again, this time to the northeast. Between Moudon and Payerne Broye uses a ausgeschliffenes from glacial Rhone Glacier valley with a broad, flat valley floor and steep, partly rocky slopes.

At Payerne, Broyetal opens out into a wide, up to 5 km wide valley basin with intensive agricultural use. Shortly before its confluence with Lake Murten Broye the left takes its longest tributary, the Petite Glane on. Murten leaves the Broye at its northeast corner. After it runs, wedged into a channel bed in the Jura water correction to the Vully and westward into Lake Neuchâtel. This final section between Murten and Neuchâtel is also Broye Canal (French: Canal de la Broye) called. A channel with a similar course was already used by the Romans, among other things, for the long-distance trade as well as for the procurement of materials for the construction of Aventicum ( quarries in the Jura ). Other inflows from left to Bressonne and Lembe, from the right Arbogne.

Only the upper reaches, the Broye yet natural shore, below Moudon it has been channelized and straightened as a result of numerous floods of the flat valley floor in the 19th and early 20th century.
