The Erf , as its name is on the lower reaches of Bavaria , previously mostly called Erfa on the upper and middle reaches of Baden-Württemberg , is a forty kilometers long left and southeast tributary of the Main in Baden-Württemberg and Bavaria (Germany).
Surname
The name of the river is derived from the Old High German "erpf" for brown and probably comes from the color of the water, especially during the annual flood when the otherwise tranquil water can turn into a raging river.
geography
course
The river has its source near Buch am Ahorn in the Main-Tauber district , a district of the Ahorn municipality in the building land . Its source is about 391 m above sea level. NHN and about 1.3 km northeast of Buch am Ahorn on the southern edge of the Machlanden forest that is part of the large Ahornwald forest area . From here he first crosses the books clearing island with the village itself in the middle of the southwest to the otherworldly forest Won Buschwindröschen to begin a turn to the north-northwest and through the re-open Upper Valley to achieve at the end of court Stetten.
From here on it moves in a very steady direction through the associated villages of Erfeld and Bretzingen in open fields, mainly on the left on the edge hills but often accompanied by forest, to Hardheim itself, where it flows for a short distance to the northwest. From the welfare mill he strives in the meanwhile deeply cut, narrow and uninhabited valley in the old north-north-westerly direction, between the wooded slopes Wolfsgrube right and Kappelberg left. Then the Katzenbach runs to him at Hofgut Breitenau (in Hardheim) from the right through the Katzental and he turns to the northwest.
Immediately afterwards it crosses the state border to Bavaria and then reaches the Lower Franconian valley village of Eichenbühl-Riedern. Behind the smaller Pfohlbach, a longer uninhabited valley section joins again to Eichenbühl itself, after which the Kohlbach flows in from the right, the Erf turns to the west and its valley widens to the funnel. In the middle is Bürgstadt , through which the Erf then from the left to about 125 m above sea level. NHN flows into the Main, less than two kilometers from its southern tip near Miltenberg .
Catchment area
The 246.91 km² catchment area of the Erf lies in the natural areas of building land , sandstone-Odenwald and sandstone-Spessart . A good two thirds of it lie around the upper and middle reaches in northern Baden-Württemberg, where the river is usually called Erfa , and the remaining almost third in Lower Franconia in Bavaria. It drains it over the Main and the Rhine to the North Sea .
The catchment area borders
- in the northeast to the catchment areas of the two main tributaries Haagbach and Wildbach
- in the east to that of the Schönertsbach , which drains over the Tauber to the Main
- in the southeast to that of the Tauber tributary Brehmbach , to that of the Umpfer tributary Schüpfbach and to that of the Umpfer itself, which also flows into the Tauber
- in the south to that of the Rinna , which drains into the Neckar via the Kirnau , Seckach and Jagst
- in the southwest of the Seckach itself
- in the west to that of the Marsbach , which drains into the Main via the Billbach and the Mud
- and in the northwest to that of the mud tributary Weilbach .
While open farmland predominates on the upper reaches of the Erf, the Erf flows from Hardheim through a narrow, wooded and sparsely populated valley. On the last kilometers, between Eichenbühl and Bürgstadt, the vineyards of the Centgrafenberg vineyard are located on the right slope of the Erftal .
