The Roethgraben is a slightly more than one kilometer long left tributary of the Buchgraben near the village of Ostheim in the Westheim community in the Weissenburg-Gunzenhausen district in Central Franconia .

geography

course

The Roethgraben rises at an altitude of 592  m above sea level. NN east of Ostheim on the northwest slopes of Rechenberg below a cave in the forest. It always flows in a north-westerly to westerly direction. After less than 500 meters, he leaves the Stockholz forest , in which he has taken a very short left tributary, behind him and then follows a corridor in the middle of its natural hollow field paths. After about 700 meters, from the right, a forest nose flows into a 400 meters longer right forest stream, this time a bit longer, after which it feeds a chain of half a dozen small ponds one after the other. After a bend to the west, it touches the Ostheim sports field on the north side and runs through a somewhat larger pond a few steps before its receiving water. After exiting again, the Roethgraben flows after a run of around 1.3 kilometers in total at an altitude of 474  m above sea level. NN northeast of Ostheim from the left into the book moat.

Catchment area

The Roethgraben drains about 0.7 km² in a total roughly west-northwest direction to the Buchgraben, whose own upper course catchment area borders on the northern watershed. In the course of the following section to that of the "western" Rohrach in the east, the highest points in it are on the northern Rechenberg at up to about 638  m above sea level. NN near the source of the Roethbach. Subsequently, beyond the southern watershed, the Riedbach competes with the Bruckbach , which only merged slightly above in Ostheim from the Buchgraben and a smaller upper course. All competitors in the area also ultimately drain into the Wörnitz .

The catchment area is located in the natural area foothills of the southern Franconian little west of the northern tip of the Hahnenkamm , the source and the top run in the Jurassic , one layer of which covers the island Rechenberg, the remaining portions of the Brown Jura .
