The Kirnau is an almost 24 km long left tributary of the Seckach in the northern Baden building land .

It arises just north of Altheim , flows only in southern südsüdöstliche to directions, then abruptly southwest, which happened Limes town Osterburken , forming in Adelsheim a small tufa - waterfall and flows there from the left in the Seckach. With almost the same water flow, it is their largest tributary and exceeds this here in length by about 8 kilometers.

Its own largest tributary is the Rinna , about 9 km long , which flows in a little above Rosenberg at its bend in the direction of its lower course. Another of the tributaries is the Brünnbach flowing to the left , it flows into Adelsheim shortly before the confluence of Kirnau and Seckach and competes with the Hergstgraben .

geography

Origin and course

In Osterburken

Kirnau passes Adelsheim Castle

While the TK25 does not clearly name any origin and labels three of the five possible spring branches with their own names, the sources offered by the LUBW consistently draw the Roscheltgraben spring branch mentioned in the TK25 up to its origin as Kirnau. A different definition would only result in a slight change in the overall length. We follow this convention here.

The Kirnau rises about 3 km east-northeast of the center of Buchen-Hettingen, namely about 100 m east of the junction of the Römerstraße / Alten Straße from the L 518. It initially flows east-south-east, and after a little more than 1 km from the left it joins the Heutelsteingraben and after almost 3 km, on the outskirts of Altheim, again from the left the stream that emerged from the confluence of three northern spring branches, takes its direction and now flows for a long time in directions from south to southeast.

Before the southern end of Altheim it takes on the Brügelgraben from the left , at the end of the village from the right a draining channel from the Schalltal shortly thereafter another from the same side. Shortly before the Untermühle, the Holzgraben flows from the right , and a little afterwards from the right the Mühlformtalgraben . After about 7 km of its course, it reaches Rosenberg- Sindolsheim , at the downstream end of which the Grundgraben flows from the left . After about 9 km it passes the Sindolsheimer Talmühle, after about 10 km and just before the Gaimühle it reaches the Sindolsheimer Graben from the left . While it previously took a fairly straight path, it now lays itself in meadow meanders, a little below it also begins to form valley meanders. It takes its largest tributary, the Rinna , about 1 km further from the left and then flows consistently in its direction to the southwest towards its mouth.

After about 12 km you will pass the old center of Rosenberg, which lies in a right loop on the right slope of the valley. A little below the Birkengraben flows from the left , then immediately at the valley mill of Rosenberg (almost 15 km) from the right the over 4 km long, sometimes dry valley of the Wammersgraben and a smaller, constantly water-bearing valley of Dörrhof. Almost another kilometer down the valley, you flow from a forest valley to the right of the Gießer Graben . Shortly before the Osterburkener Talmühle and at it you reach two more watercourses from the left, then it flows through the town of Osterburken, where shortly after the old town (approx. 19 km) the brook through the Hahnklinge and at the end of the village still that through the Hagerklinge from the left they flow. After a little over 22 km, it reaches the outskirts of Adelsheim, a little afterwards takes on the Brünnbach from the left and, when it reaches the old town border, feeds a moat going off to the right, which flows around it in an arc to the northwest and then southwest and about 200 m upstream itself flows into the Seckach. The Kirnau has covered a distance of almost 24 km at its mouth, the Seckach itself about a third less.

Catchment area

The catchment area of ​​the Kirnau covers 101 km².

In the far north it borders on the Erfa , which flows north and flows into the Main , with which the watershed between Neckar and Main stretches from west to east a little above the sources of both Kirnau and its tributary Rinna.

East of the sources of the Rinna are those of the Umpfer , which also flows over the Tauber to the Main. Further south, namely approximately east of Rosenberg, the catchment area of ​​the Jagst tributary Kessach joins, where its tributary (Berolzheimer) Kästle competes directly . Between Osterburken and Adelsheim, the catchment area of ​​the smaller Hergstbach with its feeders is squeezed between these two catchment areas to the east .

To the west of the Kirnau, the Rinschbach , another tributary of the Seckach, competes over the entire length of the river , which, after having come close to the Kirnau just half a kilometer earlier, flows into the Seckach just under two kilometers above it. With its three directions east-south-east, south-south-east and south-south-west, the course of the Kirnau has roughly the shape of an arch open to the west, the north-south of which is the Rinschbach chord.

Tributaries and side valleys

The limestone - karst landscape of building land is characterized by many dry or dry falling valleys of partially small size, so those which opens into Kirnbachtal valleys below are listed with. In these, the routes of the climbs to the surrounding hills typically run in the middle, the watercourses in them are often led as inconspicuous ditches next to the road when it is dry, but can sometimes lead to considerable amounts of water in heavy rainfall.

• H Beutelsteingraben, from the left near Altheim, 1 km
• (Dry valley Forntal ), from the right near Altheim, 1 km

• Holzgraben , from the left in front of the Altheimer Untermühle, 4 km (upper course Dörntaler Graben )
• Mühlformtalgraben , from right to the Altheimer Untermühle, 1 km (temporarily dry valley, ditch next to the road)
• Grundgraben , from the left at the downstream end of Rosenberg – Sindolsheim, 2.0 km

• (Bach from the Hahnklinge ), twisted from the left at Osterburken train station, 2 km
• (Bach from the Hagerklinge ), from the left at the downstream end of Osterburken, 1 km
• (Brook from the Fuchsenloch ), from the left opposite the fork in the railway line below Osterburken, 1 km (dry valley, an intermittent water-bearing brook for a little more than the last 100 m before the mouth)
• Brünnbach , from the left a little above the Adelsheim-Ost train station, 5 km ( left )

About 300 m before the confluence of the Kirnau into the Seckach , a moat goes off to the right, which surrounds the old town to the northeast, north and then northwest and flows into the Seckach after a little more than 400 m, about 200 m above the Kirnau itself .

traffic

Most of the Frankenbahn Stuttgart - Würzburg runs in the straight line, about 18 km long as the crow flies, running from southeast to northeast of the lower Kirnau and Rinna valleys. In the area around Rosenberg, where the valley is narrow and meandering, it avoids the valley floor.

The B 292 Sinsheim – Königshofen runs along the lowest Kirnau between Adelsheim and Osterburken in the valley, but then climbs the south-eastern slope and leads past Rosenberg and Hirschlanden on the southern heights, then turns east and moves away from the Rinna .

In the upper Kirnau valley, the L 518 runs in the valley between Sindolsheim and Altheim.

Protected areas

The valley of the Kirnau between Hirschlanden and Osterburken was designated as a nature reserve and landscape protection area with an ordinance of the Karlsruhe regional council of May 19, 1994 under the name Kirnautal with a size of around 205 hectares . The nature reserve has a size of around 87 hectares (protected area number 2.177), the complementary landscape protection area is 118 hectares. (Protected area number 2.25.033). Both protected areas are part of the FFH area 6522341 “Seckach and tributaries” , which is 1,624 hectares in size.
