Neger (Ruhr)
BW
The Negro is a southwestern or orographic left tributary of the Ruhr in North Rhine -Westphalia ( Germany ). After a generally northward course of 17.7 kilometers in length it reaches a water flow of the average well 1.3 m / s
Geography
Course
The Negro rises in Rothaargebirge on the northwest flank of the mountain Klapper ( 729.9 m) at an altitude of 722 m above sea level. NN. Your source is approximately 1.5 km (airline ) northeast of Rehsiepen, a district of Schmallenberg.
First, the Negro flows into the east. After 1.5 km distance, the direction of flow bends southwest of Mount Frettloh ( 643.9 m above sea level. NN ) abruptly to the northeast. At this point, open several short rivers that flow to the Negroes of the slopes of the surrounding mountains. Henceforth, the Negro flows parallel to the main road 742, the valley widens now abruptly to a broad glaciated valley with karartigem valley. About 1.4 km downstream flows right Gutmecke, another 600 m later also the right side Renau, which flows past the hunting lodge Siedlinghausen shortly before her mouth close. It provides hydrographic considered the main river, since it is not only longer, but also 40 % higher water content than Negroes. When Mühlenhof opens on the left side, the coming out of the Hunaumassiv Birau ( Gier ), which drains a two hundred meter deep glaciated valley.
The first village on the Negro is Siedlinghausen. Here the right side opens the Nameless ( Lamelofe ), which originates northwest of Winterberg and 8.4 km in length is the longest tributary Negro. Between Siedlinghausen and Brunskappel opens on the right side the Hambkebecke before the negro a reservoir flows through 1 ( 428.9 m above sea level. NN ) of the power plant Stone Light. On the southern outskirts of Brunskappel left side flows the Hart Mecke. In the section between Brunskappel and Wulmeringhausen both sides open several short rivers that flow off the slopes of the surrounding mountains. Between Wulmeringhausen and Stone Light, a hamlet in the city of Olsberg, flow on the left side and a Fauleborn Lazy Siepen
Finally, the Negro flows with Light stone between the mountains (height in meters above mean sea level; NN ) Stone Light ( 612.7 m; in the northwest), Narrow mountain ( 714.2 m; west) and Wiedegge ( 732.3 m; in the West southwest) and Heidkopf ( 715.3 m; in the east) on the left side to 352 m above sea level. NN in the Ruhr. The Negroes here leads around one sixth more water than the Ruhr as namentlichem main river and surpasses this also a good 8 kilometers of length ( with Renau ). Immediately to the Negro mouth comes the L 742 on the highway 480
Between source and mouth of the Negro overcomes 370 m difference in altitude, which corresponds to an average bed slope of 20.9 ‰.
Tributaries
The most important tributary of the Negro is the 10.2 km long Nameless. With its 15.376 km ² large catchment area they drained 28.5 % of the territory of the Negro. The following are the tributaries of the Negro are listed in order from source to mouth.
Negroes and dysentery compared
Until her mouth negro (17,7 km, about Renau 19.1 km ) is not only longer than the Ruhr (16,7 km, about Hille 17.7 km ) up to that point, but also has a slightly larger catchment area ( 53.883 km ² vs. 52.977 km ²). The average discharge of the Negro is more than 1.3 m³ / s compared with 1.1 good m³ / s of the Ruhr. Therefore, the Negro is at least equal standing waters at the mouth.
History and Economics
The former village of Negro near Siedlinghausen was abandoned around 1550.
The projected from 1976 Negro Dam near Brunskappel with 44.5 million m³ storage volume ( low water regulation ) was not realized, as above Siedlinghausen the later planned Renau dam with a storage capacity of 18 million cubic meters (drinking water) ..
Above Siedlinghausen and from Wulmeringhausen the negroes of the water quality class I-II is associated with, in between lies a range of grade II The structural quality is still hampered by several barriers.
