Dams

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.

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…

As part of the construction of the new Inn joint power plant in the Swiss-Austrian border region, a new dam is being built. It consists of the weir, the headrace intake for the power plant located on the orographic right bank of the Inn, the fish ladder as well as the doping power plant. The doping power plant ensures a dynamised minimum water discharge into the Inn, which is currently subject to…
