The Wehrbach is a brook in the Steigerwald foreland in the area of ​​the town of Iphofen in the Lower Franconian district of Kitzingen , which, after a roughly 5 km long, essentially south-westerly run near the town, joins the other upper reaches of the Siechhausbach to the Sickersbach . The brook arises on the southern slope of the Schwanberg at about 412  m above sea level. NHN . It is a 3rd order flowing water all year round .

geography

Right main strand upper course

The Wehrbach rises on the south-eastern, wooded flank of the Schwanberg (summit at 474  m above sea level ), east of the castle of the same name . In a steep Kerbtal valley it first runs south, receives a short tributary from the left, and then more and more towards the east. Already a little flatter, it flows around the Kirchberglein 348  m above sea level in a wide right curve sweeping to the east . NHN , in order to finally find its final course south of this hump in the direction of the west-south-west. From now on, vineyards accompany the brook on the south-facing slope to the right to the city limits of Iphofen. Even east of Kirchbergleins flows very short, south of it, a 800 m long inflow from the forest Winter Klause from left to, and immediately take a brief source stream from right out of the water arc whose Wiesental depression separates the Kirchberglein from the slope down the valley and the Briefly interrupts the vineyard sequence. Up to this inflow, the Wehrbach has lost 124 m in height on a mere 2 km course, the gradient is therefore considerable at around 62 ‰. From now on it approaches the district road KT 19 Birklingen –Iphofen (in the village: Birklinger Straße ) in a flatter course and at an acute angle , which it finally crosses.

Left main strand upper course

The northern drop of the Ringsbühlrangen of the wooded Kalbberg ( 412  m above sea level ), which is now in the south, is drained towards the Wehrbach by three longer sloping brooks, which gather in a brook running a little south of the district road, which flows into the Wehrbach from the left and east immediately after it has crossed the road . Their sometimes multiple sources are up to 323  m above sea level. NHN height, with about 1.1 km on the longest strand and a partial catchment area of ​​about 1.1 km², this is about 241  m above sea level. NHN is the most important tributary of the Wehrbach, next to the road that converges, and some people have only started its name at this inflow.

Lower course

A good 200 meters after this tributary, the Wehrbach flows into the approx. 0.9 ha large Ringsbühlsee , which takes two more short inflows from the Kalbbergshang from the forest. On the section below this lake, the Wehrbach is sometimes also called Ringsbühlbach . It soon leaves the edge of the forest behind to the left, the valley widens and becomes very flat and there are now vineyards in the Iphöfer Kalb area on the left slope . The Wehrbach, still accompanied by a wood gallery, passes a group of ponds, takes up a ditch that only carries water for a while from the vineyards and, after crossing a pond, changes back to the northern side of the district road.

In a park-like area in the Iphöfer Weichbild, it now feeds the city lake on the southeast corner, an approximately 2.8 hectare area of ​​water with an almost square contour, around which a path extends. Two temporarily dry drainage ditches from the local vineyards also run towards the city lake from the east-northeast and the north. The Wehrbach leaves the lake at its north-west corner and then reappears about 150 meters further west in the moat of the city fortifications, on the north-east corner of the completely preserved city ​​wall of Iphofen . In the trench depression, a partially branched moat runs almost completely around the city, close to which the Wehrbach, which partially feeds it, runs, initially west, then south to the tower on Kanalgasse. There he leaves the route of the city moat and follows the Geiersbergstrasse to the southwest, takes another drain from the southern city moat arch from the left and finally crosses under the street Am Stadtgraben West . In a slight curve to the right, initially through the settlement area, it approaches the Siechhausbach coming from the left and unites with this little outside the residential development of Iphofens to the Sickersbach , which initially flows westwards in the direction of the Main .

Over a length of 5.7 km, the Wehrbach has an absolute gradient of around 169 meters in altitude and thus a mean bed gradient of around 29 ‰, in the steep upper reaches of 6.2%, in the lower reaches of only 1.2%.

Catchment area

It covers about 7.86 km² and is located in the northern Hellmitzheim Bay in front of the western Steigerwald in the sub-area of ​​the Steigerwald foreland of the Mainfränkische Platten natural area . The highest point in the catchment area is the Schwanberg , a western spur of the Steigerwald north of the source area, which is 474  m above sea level. Reached NHN .

The bay is located on a larger watershed, the waters to the east of it - the next main body of water is the Bibart - ultimately run in the old Danubian direction south-east into the Aisch , which also drains into the Main via the Regnitz , but into the Upper Main with one large detour through Middle and Upper Franconia, while the Wehrbach and its other neighboring waters drain via Sickersbach and other streams further upstream to the Main of the Main Triangle.

The competitors are in the east of the upper course arch around the Kirchberglein the nearby Bibart, in the south beyond the Kalbberg the other Sickersbach-Oberlauf Siechhausbach, on the northeast part of the watershed from the confluence of the two except for the Schwanberg only briefly the Rödelbach and beyond the northern watershed over the Schwanberg the Bimbach and the Gründleinsbach , whose catchment area meets that of the Bibart again, and whose outflow only reaches the Main via the Castellbach and Schwarzach .

The catchment area of ​​the two upper reaches of the Wehrbach is located in the LSG landscape protection area within the Steigerwald Nature Park (formerly protection zone) LSG-00569.01 and thus within the Steigerwald Nature Park .

The catchment area is part of the Natura 2000 network and designated as a protected area DE6327371, Vorderer Steigerwald with Schwanberg .

Geologically, the catchment area lies on the upper reaches and up to the Stadtgraben around Iphofen in Gipskeuper , while the remaining short lower reaches lie in the Unterkeuper .
