Swiss Alps: New Dam for Hydroelectric Power
- A new dam is being constructed in the Swiss Alps due to the old dam being damaged beyond repair.
- The original dam, Spitalam, was built between 1925 and 1932 and is one of the world's first large Arch gravity dams.
- Spitalam has a volume of 94 million cubic meters and is used to generate hydroelectric power.
- In the 60s, a crack was discovered in Spitalam, leading to concerns about its stability during earthquakes.
- Repairing the original dam was deemed too risky due to potential long-term damage and sediment buildup behind it.
- Building a new dam in front of the old one and flooding the space between them was the chosen solution.
- The new dam is a double curvature dam, allowing for thinner walls while maintaining strength.
- Construction involves controlled explosives, staggered tower segments, and a tunnel for water discharge.
- The project faces challenges like snow cover halting work for half the year and remote location difficulties.
- The dam project is crucial for generating hydroelectric power and maintaining electricity balance in Switzerland.
