The Sandgraben is a brook almost four kilometers long in the Lower Franconian district of Main-Spessart in Bavaria , coming from the north-west north of the Lohr district of Rodenbach from the right into the Main , north of the Lohr district of Rodenbach , including its longer right upper course Lochbrunnengraben .

geography

Spring streams

The sand ditch arises from the confluence of the Lochbrunnengraben and Landgraben .

Lochbrunnengraben

The two kilometer long Lochbrunnengraben on the Unterlauf also known as Kleiner Graben is the right, longer and more water-rich source stream. It is therefore also seen by many as the upper reaches of the sand ditch .

The Lochbrunnengraben rises south of the Lohrer district Wombach im Walde at an altitude of about 300  m above sea level. NN at the Hägwiese in the Wombacher Loch the Lochbrunnen . Its source lies in the area of ​​the Wombach district in the Lohr-Rothenfelser Main Valley .

The Lochbrunnengraben initially flows about 40 m northwards through the forest and then enters a forest meadow tongue. It runs in a north-northeast direction about 800 m through the meadow, partly also on the left edge of the forest. To the south of a sports field, it then picks up a forest stream on its left. At the area of ​​the Lebenshilfe for people with disabilities Main-Spessart eV it reaches the locality of Wombach and is fed almost 300 m downstream south of the street Zur Wolfwiese on the same side by another small forest stream. The Lochbrunnengraben now disappears piped into the underground and runs east-northeast along the Bachstrasse . When Hirtenackerweg it flows underground verdolt turn on the left, a small town ditch. The Lochbrunnengraben now crosses the Wombacher Straße and then reappears on the surface east of the Church of St. Peter and Paul. It then moves south-south-east along the western edge of a green area and finally joins the left Landgraben to the Sandgraben south of the Herrenackerweg .

Land moat

The approximately one kilometer long ditch is the left and smaller source stream of the sand ditch . It is therefore also seen by many as its tributary. On old maps, however, the unified stream flows into the Main under the name Landgraben .

The only intermittently water-bearing Landgraben appears in Lohr at the southern end of the western bypass opposite the confluence of the street Am Landgraben on the surface.

It first flows southwards through fields and meadows in the west of the Lohr-Süd industrial park , then crosses under the Neuer Weg and changes to the Wombach district. It then runs south-south-east along the eastern edge of a green area and then joins south of the Herrenackerweg with the right Lochbrunnengraben to form a sand ditch.

course

The now unified sand ditch flows east-southeast through farmland, still crosses the state road St 2315 and finally flows about half a kilometer north of Rodenbach at an altitude of 147.3  m above sea level. NN at about Main km 194.6 from the right into the Main flowing in from the north .
