Level house (Bad Düben)
The water level house is a historically significant building from 1893 in Bad Düben , which was used to measure the level of the Mulde until 1995 .
history
The measurement of the water level in the Mulde took place in Bad Düben from January 1, 1824, using a bar gauge on the bank of the Mulde . The gauge house was built in 1893 and is located next to the Mulde river in Bad Düben at kilometer 68.1 above the confluence with the Elbe. It is an octagonal clinker brick building with a tent roof and is of importance in terms of both architectural and technical history. The octagonal building consists of 8 side walls in which an access door and three windows are integrated. Inside there is a floor opening and using measuring instruments, a so-called writing level in the house, the water levels were measured from April 1, 1893. The task of the measuring point was to determine the main level of the United Mulde , flood level, yearbook level, level with data transfer transmission. On September 1, 1995, the measurements during the construction of the new bridge and the necessary construction of a gauge house with a cable crane system were discontinued. Since then, the building has been used as a small hydrological museum and is a listed building.

Water levels
The size of the precipitation area up to the level is 6,170 km². The hollow in Bad Düben usually has a water level of around 1.65 m. Statistically, the trough has an average water level between 1.67 m (flow rate 15.6 m³ / s) to 2.34 m (flow rate 64.0 m³ / s). The lowest water level measured so far was on August 14, 1998 at 0.58 m, at the time of the flood of the century in 2002 , the highest water level was measured on August 14, 2002 at 8.7 m.
Flood warning levels
| Alert level | Guide water level | Significance and measures of the water weir |
|---|---|---|
| 1 | 5.20 m | * the river bed is full, in places smaller embankments * no endangerment of the residents * increased vigilance |
| 2 | 5.60 m | * Embankments begin, which in the case of diked waters reach to the foot of the dike * Agricultural and forestry areas are flooded, in some cases slight traffic obstructions on main traffic and municipal roads * Control of bodies of water, endangered facilities and objects as well as the embankment areas * Removal of obstacles to runoff |
| 3 | 6.40 m | * Flooding of individual properties, streets or cellars possible * Closure of regional traffic connections * In the case of diked bodies of water, the water is up to half the height of the dyke * Constant security service on the dykes by the water weirs * Implementation of preventive safety measures at danger spots, removal of local hazards and damage * Start of measures for dike defense * Outsourcing of flood control materials to known danger spots |
| 4th | 7.60 m | * Flooding of larger areas, immediate danger to people, animals, objects and facilities * The stability of the dykes is at risk. Risk of flooding over the dike. * Active defense measures from dike defense to the evacuation of humans and animals |
For comparison: the statistical mean main value of the water level is 2.34 m.
