The Franzosengraben is a 1.7 km long floodplain ditch to the right of the Ehebach between the parish village of Ullstadt von Markt Sugenheim and the parish village of the neighboring municipality of Langenfeld , both of which belong to the district of Neustadt an der Aisch-Bad Windsheim in Middle Franconia .

geography

course

The Franzosengraben begins its course at about 298  m above sea level. NHN about 50 meters from the course of the Ehebach opposite the Ullstadt moated castle next to the sports field on the edge of the village. From there it moves in slightly changing and never more than 150 meters from the course of the Ehebach to the east, initially between fields, later mostly next to meadows and with sporadic tree cover on the bank. Half a dozen ditches flow into it from the right, mostly from the lower right slope of the Ehebachtal, the longest of which, at around 1.0 km, is clearly fed by springs at the lower edge of the Jewish tendril in the south, the others, all of which are inconsistent, take only that temporary runoff from the surrounding agricultural areas.

The last fifth of the run is close to the border in the area of ​​the municipality of Langenfeld. Between their Lamprechtsmühle on the other side of the Ehebach and Langenfeld itself, the Franzosengraben flows out at about 294  m above sea level. NHN from the right into the Ehebachs.

Catchment area

The catchment area is about 1.6 square kilometers and only a small portion at and on the small plateau above the Jews vines wooded in the south, on the southern watershed with quite uniform to 404- 405  m above sea level. NHN has the greatest height. The catchment area of ​​the Rempelsbach , a medium-sized tributary of the Aisch , is adjacent to this in the southwest on only a short section , otherwise in the south that of a still quite long stream that flows into the Ehebach near Hambühl , the pasture ditch in the southeast, that of a tributary now above Ullstadt in the West.

In terms of natural space, the area is part of the southern (front) Steigerwald sub-area of the Steigerwald . The Franzosengraben runs in the broad Quaternary floodplain sediment band of the Ehebach. The largest part of the catchment area is in the Gipskeuper ( grave field formation ), the small plateau above the Jewish tendrils perhaps even reaches the sandstone keuper above .

history

The Franzosengraben is already marked on historical maps from the 19th century. The rather irregular course also points to an older creation.
