Dams

The Leibis/Lichte dam is the second largest dam in Germany and is used to supply drinking water in eastern Thuringia. The dam system consists of the main dam and the Deesbach reservoir. The raw water discharge and the ecologically required minimum discharge are used to generate energy.

The Malter dam was built between 1908 and 1913. It is located north of the town of Dippoldiswalde in the Eastern Ore Mountains. The dam is a gravity dam made of quarrystone masonry with a solid cross-section. The historic structure is primarily used for flood protection, local recreation and hydropower generation.

In order to restore flood safety, it is necessary to lower the collecting channel…

The dam was put into operation in 1914. Its main purpose is to provide raw water and flood protection for the region and the state capital Dresden. The dam is an Intze gravity dam made of quarrystone masonry with a curved axis. Following damage caused by ageing and as a result of the 2002 flood, the complex was extensively refurbished between 2006 and 2013.

The Lichtenberg dam was put into operation in 1975. It is used to supply drinking water, for flood protection and to raise low water levels. Urgent maintenance work is required on some components, in particular on the connection joint between the dam complex (KBW) and the asphalt surface seal (AOD). The measures on the connecting joint require the dam to be emptied. During this time, a costly…

Stadtwerke München (SWM) operates the Großhesselohe weir facility built in the 1920s on the Isar in the south of Munich. A replacement for the weir system is intended to guarantee the functions of flood protection and water regulation in the future as well as create ecological continuity at the site.

The planning includes the new construction of the weir on the Isar with three new weir fields and…

For the main tributary catchment areas of the Danube in Bavaria, the catchment areas of the Regen, Lech, Naab and Isar rivers, possible sites for the construction and expansion of large flood retention basins with a potential supra-regional impact were to be identified and evaluated. Restrictions relating to settlement areas, transport routes, hydropower plants and the specific storage volume had…

The end of lignite mining in the Senftenberg region has resulted in the creation of a chain of lakes from the remaining holes in the former open-cast mines. The connecting channels between the mining succession lakes to be created have already been completed. Lakes Geierswalde, Partwitz, Großräschen and Sedlitz are connected via canals and will have corresponding lake water levels in the future.…

The Aldingen barrage is one of 27 barrages on the navigable Neckar between Plochingen and the confluence with the Rhine and consists of a lock, a hydroelectric power station and a weir system. The barrage is spanned by a box girder bridge.

At almost 80 years old, the weir in Aldingen has already exceeded its calculated lifespan and therefore requires fundamental repairs or a new replacement. In…

The Quellitzsee dam was completed in 1979 and has been operated by the municipality of Döhlau as a bathing lake ever since. The lake is approx. 900 metres long, 80 metres wide, 6 metres deep and has a total storage capacity of 130,000 cubic metres. The dam is an earth dam with an inner seal made of clay. It has a crest length of 90 metres, a crest width of 6 metres and a height of 8 metres above…

Reliability deficits were identified at the extraction tower of the drinking water dam built between 1960 and 1966. The standardised load-bearing capacity could not be demonstrated under the exceptional impacts, failure of the existing drainage under full damming as well as failure of the ice-free system at the operating damming target and one-sided ice pressure. The operational safety of the…
