Description

The character reserves of the Igelsbachsee reservoir, the peninsula within the Kleiner Brombachsee, the Brombachmoor and the Sägmühle are also located on the Brombachsee. The water level of the Kleiner Brombachsee, like that of the Igelsbachsee, which is fed by the second massive tributary Igelsbach, is kept largely constant by a pre-dam. At the Eckersmühlen lock it’s channeled from the upper water into the immediately neighboring Rothsee, a reservoir created within the Kleine Roth valley. The Danube-Primary transfer system includes a complete of three lakes, including the Altmühlsee with a ring dam and two dams with Brombach and Rothsee, which embody 5 dams due to their pre-dams, three hydroelectric power plants at the dams and the Hilpoltstein lock, the canal routes to the Altmühlsee and from there to Brombachsee in addition to 27 different weirs on watercourses, a few of which have been expanded to accommodate higher water move. This water then flows by way of a energy plant with 3 megawatts of electrical output on the Hilpoltstein lock with a head of 24.67 m. Since then, it has hosted numerous Max Planck young research groups and Alexander von Humboldt scholarship holders and, with the School of Engineering, has been concerned in the 2 Excellence Initiative establishments that have been arrange on the College of Erlangen-Nuremberg in 2004. Since 1994, water has been pumped from the Danube to the highest of the canal utilizing pumps at the 5 locks on the southern ramp of the canal, from the place it flows downwards over another barrage into the Rothsee, where the water is saved and, if obligatory, in two different ways can be delivered to the Regnitz. This is done via a energy plant with a design output of 630 kilowatts (two by-circulate turbines with 315 kW every). 9.Zero m³/s can bypass the power plant. As well as, floodwater in the upper Altmühl near Ornbau is diverted into the switch system, which is intended to protect the Altmühltal under from flooding. When the Altmühl floods, excess water is channeled into the 5 km lengthy Altmühl feeder near Ornbau to the Altmühlsee. Without the addition, the Regnitz can carry lower than 10 m³/s of water at the Hüttendorf gauge in dry situations. With the Danube-Primary transfer, the water management authorities of the Free State of Bavaria divert water from the Danube river system into the Regnitz and Fundamental system in Franconia, which is threatened by short-term drought. There are additionally components and facilities of the main-Danube Canal that concurrently serve different functions: the canal itself between the connection to the Danube and the outlet into the Schwarzach, along with the inlet and outlet structures, as nicely as the pumping stations on the south ramp.While inside the title Fundamental-Danube Canal the rivers in the phrase correspond to the geographical arrangement on the north-dealing with map, the time period Danube-Essential transition reflects the circulation direction of the water pumped from the Danube and flowing towards the primary. Its longest tributaries also stream into this lower section of its course, particularly the Schwarzach, formerly also the Sulz, which has now been cut up due to using its valley and water for the primary-Danube Canal and its predecessor, then the one that, to a sure extent, represents it immediately Canal itself and eventually the Weiße Laber, all left-hand tributaries, whose great length and catchment area displays the way more distant location of the left watershed to the Rhenish system in this area. This water will enhance the water quality of Regnitz and Major, which has been affected by intensive industrial and agricultural use. This introduced with it significant restrictions on use and ecological dangers, e.g. B. for the removal of financial institution filtrate for irrigation of the Middle Franconian vegetable growing space, which solely grew to become attainable with the switch, or by way of using cooling water, etc. In the long term, a mean annual switch by way of your entire system of 150 million m³ of water is expected, 5/6 of that by way of the primary-Danube Canal. When water is low, water can also be launched from the lake back into the Altmühl, but as a rule it’s initially transported from the Altmühlsee via the 8.7 km lengthy Altmühl overpass, which crosses under the watershed in a tunnel over a distance of 2.7 km the Kleiner Brombachsee and from there into the instantly adjacent Großer Brombachsee. Between 1995 and 2013, a median of 27.9 million were bought this manner each year. M³ of water over the water sheath was transferred, after the end of the installation, a median of 26.5 million m³ had been transferred in 1999-2013 and 28.7 million m³ from the Brombachsee had been given, whereby 11 million m³ of additional inflow from the catchment area of ​​the Brombach turns into. In the years 1994-2013, an average of ninety seven million m³ of water had been t
