geography

course

The Altfelder trench created in the Sandstone-Spessart in the natural area 141.2 Oberwittstadt Bacher Spessart foreland in the field of the district of Marktheidenfelderstraße district Altfeld from two source branches.

The southern main source load arises at a height of about 295  m above sea level. NHN in the corridor Kirchweg Feld above the Sauerweg on the southern edge of the Altfeld industrial area I-II directly south of Michelriether Straße, a source that only carries water intermittently .

The strongly straightened stream flows first, lined with a meadow on the right and a field on the left, about a hundred meters south-southeast and then bends north of the MSP 31 district road leading from Michelrieth to Triefenstein to the east. Accompanied by the district road, he now runs for almost three hundred meters through the fields of the Langer Grund corridor and is then fed on his right side at the level of the road Am Schloßfeld by a small ditch along it. It continues to run eastwards for a good two hundred meters along the northern edge of the Altfeld IV industrial area, then between fields on both sides of the road. At the next junction of the side road, a good hundred meters down the stream, another field ditch runs towards it from the right. Two hundred and fifty meters later it crosses diagonally under the M 31 / B 8 intersection . North of a motorway maintenance depot , it then disappears underground and joins south of Wertheimer Straße with the second, northern source branch, which arises on the edge of the Altfeld settlement area to the tissue zone around the street Am Jöspershecklein , briefly flows on the surface to the south-south-west and then largely underground runs.

The now unified Altfelder Graben flows south of the alley Am Graben south-east, then leaves the village and soon afterwards enters the forest in a now deep valley notch. A good hundred meters later, the Kirschengraben coming from the northwest runs towards him on his left . The Altfelder Graben now passes the municipal boundary to Triefenstein and changes to the district of its suburb of Trennfeld . He then squeezes east through a narrow and steep gorge . At the end of this it bends at a dirt road on the edge of the Mainaue as its sloping ditch almost at right angles to the south-southeast.

Two hundred meters further on, it takes the branching off of a stream running towards it, which in its main course strives so much further downstream to the Main, crosses under the dirt road there and continues on the other side in a ditch, which after another hundred meters towards east-northeast finally in the lower main valley in the natural area 141.02 Marktheidenfeld-Wertheimer main valley at an altitude of 142  m above sea level. NN at Main kilometer 176 from the right flows into the Main flowing in from the north.
