Heightening very high gravity dams is one of the solutions considered as part of the energy transition and to mitigate the effects of climate change. The paper presents a stepwise approach to assess the potential for dam heightening and its impact on the h ...
Dams are civil structures essential to modern civilization. However, they can be a threat if not properly designed and operated. A particular risk that potentially can lead to dam failure is the blocking of the spillway inlet with driftwood or debris. This ...
Hydropower has a long tradition in Europe and contributed significantly during the last century to industrial development and welfare in most of the countries in Europe. The ambitious plan for an energy transition in Europe now seeks to achieve a lowcarbon ...

Dam heightening can provide large incremental positive impacts on storage with minimum incremental negative impacts, but requires deep knowledge of the structure and its foundation. Very high gravity dams are usually well studied and documented due to thei ...
A promising pathway to follow in order to reach sustainable development goals is
an increased reliance on renewable sources of energy. The optimized use of these energy sources,
however, requires the assessment of their potential supply, along with the dem ...

Only 42 % of the mean annual production of large hydropower plants in the Swiss Alps is stored in their reservoirs. Once the reservoirs are full at the end of the summer semester, plants are operated as run-on-the-river in order to avoid spilling. A signif ...
