The Friedrichsgrundbach is a tributary of the Elbe in the east of Dresden . It is named after the Friedrichsgrund , a side valley on the right bank of the Elbe, which extends between the Dresden district of Pillnitz and the Meixmühle.
course
The stream rises in the Reitzendorf district of Dresden . It flows first in a southerly direction, then in a south-westerly direction. After 4.3 kilometers of flowing, the brook flows north-west of Pillnitz Castle orographically right into the Elbe.
In the upper reaches the brook runs through Reitzendorf. There buildings, traffic areas and ditches extend right up to the water. Most of the bank is paved with stones and sea walls. The stream is piped for short sections. Then the brook flows through the Friedrichsgrund. Up to the Meixmühle it is in a natural state there, and is piped to the mill itself. As far as Pillnitzer Meixstraße, the stream runs again in an often unobstructed bed. To maintain the parallel hiking trail, there are dry stone walls on the right bank. As soon as the development boundary of Pillnitz on Meixstrasse is reached, the Friedrichsgrundbach is enclosed on both sides with bank retaining walls. The sole is paved with natural stones there. On the wall of Pillnitz Castle, the stream divides into the orangery ditch, which feeds the English pond, and into an underground tunnel. After 200 meters the parts unite again and shortly afterwards flow into the Elbe.
In the 4.3 square kilometer catchment area of the Friedrichsgrundbach there are twenty near-natural to partially natural seepage, flowing and linear springs: the Friedrichsgrund-Seitengrund sources 1 to 14, the Vogelgrundbach source and the Vogelgrund-Seitengrund sources 1 to 5. The Land use in the catchment area is predominantly characterized by agriculture.
Water condition
Due to its catchment area of less than 10 square kilometers, the Friedrichsgrundbach is not a separate body of water according to the European Water Framework Directive (WFD). The brook belongs to water body type 5 (WFD): "Coarse material rich, silicate low mountain brooks". The Friedrichsgrundbach is an Elbhangbach with a steep slope. The stream bed mainly consists of substrates rich in coarse material such as stones and gravel. The geological subsoil is characterized by granodiorite , block rubble and loess loam . Valuable structures made of dead wood and flotsam can be found in sections in the near-natural upper reaches .
There are no water retention or dam systems in the course of the Friedrichsgrundbach. Rainwater is discharged at one point in Reitzendorf and at four points in Pillnitz. A bed load trap and four flotsam traps were set up in Pillnitz.
natural reserve
The Friedrichsgrundbach is located in the nature reserve "Dresdner Elbehangs" and in the landscape protection areas Schönfelder Hochland and Elbehangs Dresden-Pirna as well as in the FFH area Elbehangs between Loschwitz and Bonnewitz .
At Friedrichsgrundbach there are 178 protected biotopes such as numerous orchards, swamps, spring areas, natural or near-natural areas of flowing and standing inland waters including their banks and the associated natural or near-natural vegetation accompanying the banks, lean fresh and mountain meadows and cave-rich islands of old wood. The occurrence of bitter foam herb is worth mentioning .
Cultural monuments on the Friedrichsgrundbach
There are numerous cultural monuments in the course of the Friedrichsgrundbach. Among other things, the Meixmühle, first mentioned in 1403, with the Drachenburg built in 1903. Shortly before its mouth, the Friedrichsgrundbach flows through the park of Pillnitz Castle.
In May 2007 , a new fountain was inaugurated on the Pillnitz village square, near the former town hall of Pillnitz . The piped Friedrichsgrundbach runs under the well. The new fountain visualizes the course of the stream. The stream itself becomes visible through a cylindrical shaft. Three water basins are reminiscent of the original shape of the fountain. The edge of the pool is made of Saxon sandstone and the bottom of the pool is made of reddish Finnish granite. The well system is fed with rain and drinking water. A circulation pump ensures water movement. The well is emptied into the stream. The fountain system cost 65,000 euros, the green area 15,000 euros. The project was financed with funds from the city and donations. The well is the successor to a well that was decommissioned in the 1990s.
Flood
In the Reitzendorf location there has so far only been local flooding with minor damage. In the local area of Pillnitz, floods in the Friedrichsgrundbach have often caused major damage.
On July 27, 1850, after heavy precipitation on the Borsberg, there was considerable runoff. In Pillnitz, the water masses carried away some houses and Meixstrasse was completely destroyed. Major damage was caused mainly by rubble. The wall of the Pillnitz Castle Park was torn down and the water or mountain palace damaged.
During a flood event on July 4, 1918, the embankment wall in the Orangeriestraße area was destroyed and Dresdner Straße was washed away. A resident was swept away by the floods and could only be recovered dead from the Elbe.
There was further major damage, especially on the river bed, but also on Pillnitz Castle Park, on May 31, 1995, in August 2002 and in June 2013 .
