Hydraulic safety of handling extreme floods of at Edensforsen dam, Sweden
2010 (English)Conference paper (Refereed)
Edensforsen is a high-hazard dam. Along with other engineering measures, a significant increase in its spillway discharge capacity is needed in order to meet the existing dam-safety criteria. A number of design options are examined in order to achieve cost-effective rebuilding. The options includes (A) the use of the existing spillway in combination with extra storage of water above the legal reservoir level, (B) modifications of the abandoned log flume into a spillway, (C) threshold lowering in the existing sector spillway (D) a new, wider spillway with the log flume removed. Some of the options might be combined. To evaluate the measures, hydraulic model studies are made of discharge capacity, energy dissipation and flow patterns downstream. The final choice of refurbishment depends mainly upon the technical feasibility and economical considerations.
