The Kleditschgrundbach is a 1.7 km long left tributary of the Elbe , which in sections marks the city limits of Dresden . It rises west of the Saxon state capital in several sources in and near Weistropp and flows through the eponymous Kleditschgrund , one of the left Elbe valleys . After its confluence between Wildberg and Niederwartha at river kilometer 70.25 in the Elbe, it leaves the Dresden city area after a good 30 kilometers.

The open stream is a sloping, near-natural body of water, only the last 140 meters from federal highway 6 to the mouth are straight and partially paved.

course

The Kleditschgrundbach rises at about 235  m above sea level almost at the western end of the forest area, which connects to the north of the village of Weistropp (municipality of Klipphausen in the district of Meißen ) . HN in an easterly direction. After about a quarter of a kilometer, on the right-hand side, it takes up the Kleditschbach ( ), which comes from the south and rises east of the Weistropper Church , and which has the longer course of the stream up to this point. Almost 100 meters further on, it takes up the Guntzschbach, which is also coming from the south, and now turns itself for around 300 meters to the north-north-east, before taking an east-north-east direction again. The stream bed in the Kleditschgrund , in the sloping sections of which a notch valley has formed, consists of substrates rich in coarse material. After the stream has covered around 100 meters in altitude over a kilometer from the source, it overflows at 134.9  m above sea level. HN the Dresden city limits and reaches Niederwartha . On the following 260 meters to the edge of the forest, it still has a gradient of 4.8%. From there it turns to the northeast, flows along the city limits and crosses under federal highway 6 . Over the last 140 meters, the gradient becomes steeper again (5.7%) and the stream crosses under the Elbe Cycle Path before it flows into the Elbe . World icon

Flood

At the Kleditschgrundbach there is only a low risk potential, because of its natural bed it can get out of hand over long stretches. In the case of medium-long heavy rain events lasting around 3 hours, the greatest peak runoffs are to be expected. Even with a centenary event, the stream only has a peak discharge of 2.61 m³ / s. Unless it is narrowed by sediment deposits, the bridge of the federal road can discharge 2.7 m³ / s in the dammed state.

The bridge of the Elberadweg at the mouth of the Kleditschbach is almost completely flooded from an Elbe level of 7 meters. When the Elbe floods, the water in the Elbe only reaches around 80 meters into the relatively steep Kleditschbach, while this can be around 400 meters in the nearby Tännichtgrundbach and almost 2 kilometers in the Lotzebach . Accordingly, the damage from the thousand-year heavy rain event on May 27, 2014 was also lost. Destructive masses of water came to Niederwartha from the Tännichtgrund in particular , while the damage from the Kleditschgrundbach was significantly less.

Protected areas

The Kleditschgrund with the Kleditschgrundbach lies in the Elbe Valley landscape protection area between Dresden and Meißen with valleys on the left bank of the Elbe and the Spaar Mountains .

  • ... and 2018

In the Dresden section of the Kleditschgrund is the Political Book ( ) on the right . As a single tree, it has been a natural monument since 1958. The red beech , once around 25 meters high , suffered a broken crown six meters above the ground in autumn 2017. World icon
