The Aalbach (from the confluence to Roßbrunn also: Ahlbach ) is a 26.5 km long, left and eastern tributary of the Main in Bavaria and Baden-Württemberg .

geography

The course of the river Aal begins at the confluence of two watercourses about 2.5 km northwest of Waldbrunn . Both branches only periodically carry water over long distances. The shorter left watercourse is called Haselbach , the longer right Waldbüttelbrunner Augraben , like the Aalbach, has the water code number 2458 and is officially counted as part of the main strand of the Aalbach river system. If the two upper courses are dry, the Aalbach only carries water permanently from the Pfetzer spring, southeast of Mädelhofen , near the ruins of the Mädelhofen hunting lodge .

Upper course Waldbüttelbrunner Augraben

Confluence of the Waldbüttelbrunner Augraben (right) and Haselbach (left)

This upper course begins on the road An der Weed in Waldbüttelbrunn at about 296  m above sea level. NHN and runs roughly west-southwest along its entire length. Its first 700 meters on the northern edge of the village to its western end are not on the main line, but rather its tributary Weidengraben is included . This, also popularly known as the Franzosengraben , is being built on the south-east corner of the Waldbüttelbrunn location near the sports fields and the Sumpfler road at around 314  m above sea level. NHN . It then flows along the southern edge of the village to its western end, where it flows from the left into the aforementioned shorter upper course of the Waldbüttelbrunner Augraben . This now continues in a little deepened terrain in the corridor, on the flat left forest hills after a little over a kilometer of forest. The B 8 accompanies him along its entire length. The Waldbüttelbrunn Augraben takes on a few tributaries from the left and right and flows northwest of Waldbrunn and 6.2 km down from the Weidengraben origin with the Haselbach at about 247  m above sea level. NHN to the Aalbach together.

Pfetzerquelle

Pfetzerquelle

If the two source streams are dry, the Aalbach only carries water permanently from the Pfetzer source. The contained spring is surrounded by some trees between Mädelhofen and Waldbrunn , at the foot of the Brunnrains (291 m), near the ruins of the Mädelhofen hunting lodge . The spring stream that sprang from there reaches the bed of the Haselbach after about 360 m. According to the Federal Transport Infrastructure Plan 2030, the planned federal highway 26n could lead directly past the source and possibly impair it.

course

The Aalbach then flows to the west with an initial curve to the north. It passes Madelhofen , crosses Roßbrunn and then the mostly right-hand Uettingen . He then passes through Holzkirchen in a narrower valley, mostly wooded on the slope, and passes the Wüstenzell district , after which he moves to the town of Wertheim in the Main-Tauber district of Baden-Württemberg . There Dertingen is mainly on the right bank, from which the A3 runs for a while in the wider valley next to the stream. After this motorway has left the valley in a northward direction, the Aalbach touches Bettingen on its southern edge and flows into this place below Main-kilometer 166 at about 139  m above sea level. NHN from the left into the Main, which here in the southeast of the Mainviereck river section just runs into the Urpharer Mainschleife .
