Sieber (river)
Southwesterly resin with Sieber ( source river here about a kilometer shorter Schluft )
The Sieber is a 35 km long, north-easterly and orographic right-hand tributary of the Oder in the Harz Mountains and south of the Harz mountains in the district of Osterode am Harz, Lower Saxony.
Course
The Sieber rises in the Upper Harz Harz National Park. Your source is in each case just south of the rupture peaks (about 927 m above sea level. NN ) and from the original site of the Skikreuzes of ski clubs Altenau at around 900 meters above sea level. NN.
Initially flows Sieber, which passes through the multi-part nature reserve Siebertal, to the south. After about 1000 m flow distance it is from the Clausthal Flutgraben ( sometimes called Rothenberger ditch ) crossed a ditch slope of the Upper Harz Water Regale. This initially extending to approximately 820 m trench passes at low tide almost all the waters of Sieber first east and then northeast to the Bruchberg around and feeds it to the dam ditch.
The Sieber even under traverse about to about 760 m altitude, the federal highway 242, and cuts from now on around 10 km flow distance a deep, V-shaped valley in the spiral wave resin a plateau. Then the valley widens slightly, and now but located outside the Harz National Park, within the Harz Nature Park river runs only in western and then southwestward along the country road 521 He touches - after inflow of Kulmke - the village Sieber directly southeast. In this village, the gold sink opens a.
Some further southwest, where the border of the national park until nearly enough to the river that flows through Sieber at open out the Lonau the core city of Herzberg where it leaves the resin and the natural park. There, a portion of its water is diverted through the mill ditch, formerly several mills were powered by the. Below Herzberg and the former munitions factory in the mill stream flows back into the screener.
From Herzberg Sieber runs - after passing under the highway 243 and railway Herzberg Seesen - in the south of the Harz mountains roughly along the county road 27 to the B243 beyond located them a short distance to the north- west, where between the Great Steinau and little Steinau to about 1,000 m length pushes the border of the nature park to the river. Then finally it flows outside the park.
After passing of Hörden and Elbingerode, the Sieber flows along the county road 7, it opens in Hattorf after passing under the southern Harz range to about 173 m above sea level. NN in the Rhume inflow Or; just below the mouth of the Oder Sieber is dammed by a small weir to a small lake ( 172.6 m above sea level. NN ).
Catchment and inflows
The catchment area of Sieber is about 141 km ². Its tributaries include with orographic mapping (l = left side, R = right side), and - if known - river length, Mündungsort catchment size ( downriver considered ):
- Schluft (r, 2.5 km), in the upper reaches slightly below the break mountain ( often referred to as Sieber )
- Fischbach ( l ;), in the headwaters of some below the break Bergs
- Kulmke (r; 2 km), above Sieber, 13.5 km ²
- Gropenborn ( l, 2 km), directly Sieber 0.9 km ²
- Gold sink ( r; 4 km), directly at Sieber, 5.9 km ²
- Well Beeke (r ;), directly Sieber
- Tiefenbeek ( l; 2.9 km ), adjacent to Sieber, 2,5 km ²
- Lonau (r, 3.5 km), Herzberg, 14 km ²
- Large Steinau (r, 7.5 miles), between Herzberg and Hörden
- Small Steinau (r; 8.7 km ), between Herzberg and Hörden
Seepage
In the Harz foreland Sieber between Herzberg and Hattorf runs through the karst landscape of the southern Harz Zechsteingürtels, so that there is (also called shrinkage) to seepage. There seeps average of almost a third of its water into the ground. During prolonged dry periods, it may even happen that the river drops at times quite dry by the seepage. The seepage in this area, water enters the nearly 9 kilometers south-west lying Rhumequelle back to the surface. One of these shrinkage was between Herzberg am Harz and Hörden in front of the steep northeast slope of Nüllbergs ( Null ). At sufficiently high water level in the Sieber here versackte part of the water. Today this place is about 20 m away from the river bank.
Karl Thürnau colored at its hydrological studies of the Rhumequelle Sieber inflow Eichelsbach ( Herzberg / Harz) in February 1910 with 6 kg of uranine. Three days later, the slightly colored water appeared in the main source of Rhumequelle. This is also confirmed in 1980 by dyeing tests conducted by the Lower Saxony State Office for Soil Research. It also corresponding compounds of Rhumequelle with the screener at Hörden and the Oder in Scharzfeld were detected.
Dam
Between the 1960s and mid-1980s were followed by the Harzwasserwerke plans to use the water of the screener with one or more reservoirs. Some plans envisaged a complete flooding of the village Sieber, on resettlement of citizens to a new location. The spa town of resettled were promised " the best possible start ." Other plans called for a high dam just before above the village. The final plans, the so-called multi-step solution that consisted of two smaller storage structures in the upper Siebertal and in the Kulmke for transferring water in the Söse and construction of the lower dam Sieber between Sieber and Herzberg. Ultimately caused strong resistance of the population from the southern Harz region that these plans were stopped. Today, the Sieber is one of the largest unregulated rivers in the Harz Mountains.
Others
The river is named after the place Sieber Siebertal, are shown by the large components as a nature reserve Siebertal.
In the Lonauerhammerhütte the water power of the screener was used for a stamp mill.
Due to the karst area in the river course in the area around Herzberg during the last 400,000 years has shifted several times. The surface of dolomite or gypsum has repeatedly altered by leaching and sinkholes. One of the former rivers ran along what is now State Road 27 through the floodplain, that is, the Sieber flowed south around the castle hill of castle Herzberg, several miles distant from the present run. An even older former course of the river ran over today Nüllfeld Pass ( between Schlossberg and Nüllberg ) to Elbingerode.
The small street in the upper Siebertal since the late 1980s locked from the forester's house royal court for motor vehicle traffic and is partly in the Harz National Park. It leads to the federal highway 242 northwest of Sonneberg.
