The Seckach flows into the Jagst

The Seckach is a small river in the north of Baden-Württemberg , which has its origin in the Odenwald and flows into the Jagst from the right and north in Möckmühl in the Heilbronn district .

The Seckach is about 28 km long, its catchment area covers 262 km². Of this, the Kirnau tributary , which is around 8 kilometers longer than the Seckach at the confluence, is around 100 km².

geography

course

The Seckach rises near the Buchen district of Waldhausen in a spring -rich area and takes on secondary branches early on. It initially flows in a south-east and south direction.

Between the communities of Seckach and Adelsheim, the Seckach takes on a few increasingly powerful tributaries. The Schlierbach flows into rooms. The Rinschbach flows between Hemsbach and Adelsheim and rises in the building land near Götzingen . Finally, in Adelsheim, the Seckach receives its largest tributary, the Kirnau, which has its origins in the building land near Altheim . What is striking at the mouth is how much the water of the Kirnau pushes that of the Seckach to the side. so that it is unclear which of the streams is the stronger. After the confluence, the Seckach can be called a small river.

On its further way towards the Jagst, the Seckach flows in large swings to the south and takes in other permanently water-bearing brooks, of which the Fischbach is the largest. It flows a little south of Sennfeld.

In Möckmühl, the Seckach used to flow parallel to the city wall and offered a picturesque perspective at a weir together with the old town. Today it is twisted over a length of several hundred meters . Its mouth was moved a bit to the south around 1900 when the Jagst Valley Railway and an electrical power station were built.

Tributaries

overview

The Seckach has five tributaries of over five kilometers in length, namely the left Hiffelbach with 7 km and a catchment area of ​​about 27 km², the left Schlierbach with 6 km and a catchment area of ​​about 9 km², the left Rinschbach with 16 km and a catchment area of about 40 km², the left Kirnau with 24 km and a catchment area of ​​about 101 km² and the right Fischbach with 7 km and a catchment area of ​​about 15 km².

fauna

The water of the Seckach is very rich in oxygen, clean and relatively cold. This fact favors the trout , which are found in abundance here. There are also eels in the lower reaches . Crayfish once lived in the Seckach .

Flood protection

After heavy rainfall on December 21, 1993, the streams in the catchment area of ​​Seckach and Kirnau burst their banks. The Seckach reached a discharge rate of 154 m³ / s near Sennfeld and thus exceeded the average discharge rate of the Neckar in Mannheim. There was flooding in the entire area, with Adelsheim, Möckmühl, Roigheim and Osterburken on the Kirnau river particularly hard hit (see also Rhine flood 1993 ). The highest water level since 1732 was measured in the old town of Möckmühl.

After another flood in 1995, the municipalities in the catchment area of ​​Seckach and Kirnau founded a special purpose association for flood protection in 1997 to initiate improvements in flood protection and flood prevention. By 2008, 15 flood retention basins had been built to protect the area from a flood of the century . Further protective measures were taken in Möckmühl in particular. There, dams and concrete walls were built on the Jagst on the old town side and on the Seckach, and devices for mobile sheet pile walls were also attached to the gates of the city wall. Walls and dykes were also built on the Jagstufer on the left opposite the Seckach.

Hydropower

Mills already used the water power of the Seckach in the Middle Ages . The town mill of Möckmühl is occupied in 1471 and probably existed for a long time, as did the neighboring Lohemühle . In the section of the river from Sennfeld to the mouth at Möckmühl alone, 23 water thrusters have been identified. Until the 19th century it was mainly grinding mills, grinding mills, sawmills, hammer mills, oil mills and the like, but from the late 19th century the water of the Seckach mainly drove turbines to generate electricity. Some small power plants along the river are still in operation today and go back to former mill locations, such as the power plant on the site of the former Gernerschen Mühle near Möckmühl. Several industrial locations in the region go back to earlier mill locations, including a. Pucaro in Roigheim or Texon and Agria in Möckmühl.

Protected areas

A small part of the Seckach valley in the upper reaches shortly before the town of Seckach was designated as a nature reserve by order of the Karlsruhe regional council of August 25, 1992 under the name Seckach valley . The NSG bears the number 2,152 and has a size of around 63.4 hectares. The purpose of protection is to secure and maintain the valuable mosaic of different habitats in this area, namely the stream with its water quality as a habitat for a diverse aquatic flora and fauna, the riparian woodland as remnants of near-natural alluvial forest communities, the wet valley meadows accompanying the water and the valley flanks, which because of their Structural wealth are an ideal retreat for a large number of plants and animals.

The nature reserve is part of the FFH area No. 6522341 “Seckach and tributaries” , which is 1,624.3 hectares in size and extends over the Main-Tauber district and the Neckar-Odenwald district.

Others

The alluvial cones are of geological interest due to the regular floods up to modern times .

Several charming old natural stone bridges lead over the Seckach: in Zimmer and Adelsheim each with two arches, in Sennfeld two bridges with several arches.
