The Moorbach is a three-kilometer orographic left tributary of the Odenbach in the Rhineland-Palatinate districts of Kaiserslautern and Kusel .

geography

course

The Moorbach rises in the district of Morbach, which belongs to Niederkirchen, at an altitude of 369  m above sea level. NHN underground a small pond .

The stream first passes the village in a northerly direction and then flows in places accompanied by bushes and trees in a wide valley almost 700 m through the fields and meadows of the Flur Im Brühl on the western slope of the Krippes ( 391.2  m ). He then turns northeast in the hallway in the pool and then walks south past a small biotope. From the corridor in the lower hub it then marks the border between the district of Kusel in the north and the district of Kaiserslautern in the south up to its mouth. Immediately afterwards the brook on its left side is fed by the little Frohnbach .

The Moorbach now squeezes through a narrow with hornbeam mixed oak forest bewachsenes V-shaped valley, that between the southwest of the village Relsberg lying Kahlberg ( 396  m ) on its left side and the hill wide tail ( 374.2  m is) on the right side. His further run then leads him first through the corridor on the broad hedge and then through the corridor in the Bocksrück . A little further down the stream, the Brühler Graben, coming from the west, flows towards him on his left .

The Moorbach now runs eastward in a strip of forest bounded to the right and left by fields through the Mohrgraben corridor on the southern slope of the Schwanenberg ( 360.6  m ), then crosses under the state road 382 ( valley road ) and finally flows between the Niederkirchen residential area Bügenmühlerhof in the south and the local community Hefersweiler in the north directly on the community boundary to Hefersweiler at an altitude of 236  m from the left into the Odenbach coming from the south .

Catchment area

The 3.4 km² catchment area of ​​the Moorbach is located on the upper course in the natural area of the Lichtenberg ridge and in the mouth area in that of the Moschel heights . Both natural areas are sub-areas of the North Palatinate Bergland and thus also part of the Saar-Nahe Bergland . The highest point in the catchment area is the Störtzelberg, north-west of Morbach, at a height of 446.4  m . Other notable hills are the 396  m high Kahlenberg southeast of Relsberg, the Krippes hill north-northeast of Morbach with 391.2  m , the Breitheck hill south-east of Relsberg with 374.2  m and east of Relsberg the 360.6  m high Schwanenberg .

The area of the bog brook bordered on the southwest by the catchment area of Lauter inflow Rossbach , as well as to the area of the tributary Gray Bach and northwest competes in the Glan confluent Sulzbach . In the north its catchment area is bounded by the Wambach tributary of the Odenbach and in the south by the Weilerbach , which has the same receiving water. The largest part of the Moorbach catchment area is occupied by sandy - loamy fields, with a smaller part also grassland. The stream meadows are mostly overgrown by forest. In the catchment area of ​​the Steinbach, the village of Morbach, which belongs to the Kaiserslautern district, is located in the southwest, and the local community of Relsberg, which belongs to the Kusel district, is located in the northwest.

Tributaries

Data

The Moorbach drains over the Odenbach , Glan , Nahe and Rhine into the North Sea . The difference in altitude from its source to its mouth is 133 m, which corresponds to a mean bed gradient of 43.2 ‰ over a run length of 3.077 km. Its catchment area of ​​3.394 km² contributes about 3.9% to the catchment area of ​​the Odenbach (85.956 km²). Its structural quality is mainly assessed as unchanged (quality class I) or slightly changed (quality class II), only parts of the Oder and the estuary area have a poorer rating.

geology

The upper reaches of the Moorbach lies in the Rotliegend of the Permocarbons in the Upper Glan subgroup . The upper part of the sediment layer consists of red, conglomerate arkose of the Oberkirchen Formation , underneath are alternating layers of gray clay , silt and sandstones . There are also tuff and limestone . The area of ​​its lower reaches is shaped by igneous rocks of the Nahe subgroup of permocarbons. There are basaltic andesite and tholeiitic basalt rock as well as a gray-black, fine-grained matrix of plagioclases , some pyroxes and specks of mostly altered olivines .

nature and environment

The marsh marigold

The Moorbach flows through two protected areas. The 17.5 ha biotope Moor-Bachtal southeast of Relsberg with the area number BK-6412-0234-2009 and the 34.6 ha biotope Moorbachtal, springy meadow valley and structured slopes with lean grassland S and O Relsberg with the area number BK-6411- 0479-2009.

Northwest of the crib is a bush hedge at ground level. Pedunculate oaks , ash trees , dog roses and sloes as well as pear and sweet cherry trees grow there . The Kahlenborn drains a fat meadow . At the of finer sediments existing block and flat banks grow of there slow-moving and easy meandering brook Moor hazels , sloes, sallow , ash and alder . At the bottom of the ground grows the forest ziest , the real carnation , the marsh marigold , the real meadowsweet , the great nettle , the small-flowered jumping herb and the great witch's herb as well as the flaky grass and the ball of grass . Common well moss grows in the water at the bottom of the stream .

The heather grasshopper

In the mixed oak and beech forest at the southern foot of the Kahlenberg you will find Scots pines , red beeches and hazelnut bushes as well as English and sessile oaks . In the herbaceous layer , wood twigs , grasses , worm ferns , golden nettles and blackberries grow and the forest there has a rich population of old trees and dead wood .

At the mouth of the Brühler Graben there is a mixed beech forest with native deciduous tree species. There are beeches, ash trees, sycamore maples , spruces and Scots pine trees. The wood sorrel , the forest sedge , the common worm fern, the great witch's herb, the spotted arum , the wood twig, the mountain gold nettle and the stinker's beak thrive in the herb layer below .

In the past on the southern slope of the Schwannenberges rough pasture that grows Red bent grass , the red fescue , the Middle plantain , the Common bird's-foot trefoil , the sheep's fescue , the cypress spurge , the Fluffy meadows and yellow oat , the True bedstraw and the White bedstraw , the Small agrimony , the sprout end clove head that ragwort , the meadows and the white clover , the meadow milfoil that field scabious , the Spring and silver cinquefoil , the Common Dost , the wild carrot , which Hasenklee , the True centaury , the Small burnet , the Common oat , the lesser saxifrage , the tufts Elke , the Rapunzel bellflower , the pigeons cranesbill and Luzula campestris . The heather grasshopper also lives there .

To the west of the L 382 shortly before the confluence with the Odenbach, the field maple , pear trees, robinia and English oak also grow in a protection zone with oak trees . There are also black elder , sloe, privet , single- action hawthorn and hazelnut. The garlic mustard , wood sorrel, gundermann , ivy , spike grass, common worm fern, common carnation and stinker's beak thrive below . The entire area is subject to lump-sum protection under Section 24 of the Rhineland-Palatinate State Care Act.
