The Neue Graben is a right, periodic tributary of the Main in the Bavarian Spessart . It arises in Hausen from the confluence of the Harzgraben and Triebgraben .

geography

Spring streams

Drive ditch

The Triebgraben rises between Roßbach and Hausen at the foot of the Eichhöhe ( 307 m above sea level ) at about 245 m above sea level. NHN . It flows in a south-westerly direction towards Hausen. It is the left and, with a length of about 1.0 km, the more water-rich source stream with a partial catchment area of about 1.3 km².

Harzgraben

The approximately 0.8 km long right Harz ditch rises north of Hausen at about 223 m above sea level. NHN . It runs to the southeast, drains about 0.7 km² and unites in the northern part of the village at about 193 m above sea level. NHN with the Triebgraben to the Neuer Graben .

course

After the confluence of the source streams, the Neue Graben runs along the district road MIL 25 south to south-west through the town of Hausen. Its largest tributary flows into Hofstetten , the Eichelsbach , which comes from the southeast . The Neue Graben then flows westwards, among other things past the northern edge of an industrial park in the already wide valley funnel towards the Main valley. It passes a first quarry pond on the north side, crosses under the route of the state road 2309 and is then almost to the last border stream between Markt Elsenfeld in the south and Markt Kleinwallstadt in the north. After he immediately afterwards also the railway line Aschaffenburg-Miltenberg has crossed, it flows at a small quarry pond on the small side Wallstadter over and then culminated earlier last on Else Fields area at the treatment plant from the right in the still Bavarian Lower main . Today, however, it is led in a ditch close to the river bank about 1.0 km to the north to the local area of Kleinwallstadt, where it is 112.5 m above sea level. NHN enters the underwater of the Wallstadt barrage immediately after the structure .

Catchment area

It covers 16.6 km² and lies for the most part, namely down to the valley widening to the Main, below Hofstetten, in the natural area of the southwestern sandstone Spessart , here the landscape is very steep and wooded at the greater heights. The smaller one in the eastern lower valley slopes down quite flat towards the Main.

In the mountainous part there is middle red sandstone in the higher elevations and lower red sandstone in the lower slopes and valleys . In the subsequent part to the right of the Main near the mouth, the river has left terraced gravel and sand behind. Below Hofstetten at the widening of the valley to the Lower Maine Plain, a fault crosses the valley in a north-westerly direction.

The catchment area borders in the south and southeast on that of the more important Elsava , which flows a little upwards into the Main, in the northeast and north on that of the Leidersbach , which drains further downstream into the river via the Sulzbach . On the north-west side, the smaller bush trench that runs up to it just below Kleinwallstadt competes.

By far the largest mountain Eichelsberg rises in the east near the headwaters of the largest tributary Eichelsbach a little north of Eichelsbach , its summit reaches about 406 m above sea level. NHN . Only on this side of the Elsava watershed is the ridge over 300 m above sea level. NHN , almost everywhere else below.
