Gallejaur dam safety – hydraulic concerns related to spillway flood discharge

Abstract [en]

In dam-safety evaluations of Gallejaur dam, commissioned 1965, a few safety issues were identified. The main concern is associated with use of the spillway for discharge of higher floods in light of the updated design-flood criteria. The operation of the dam has indicated insufficient energy dissipation that gives rise to frequent damages in the erosion protection of blasted rock riprap in the spillway canal. The canal has also too low sidewalls that have to be heightened in order to prevent overtopping during higher floods. Hydraulic model tests are conducted to serve as a basis for examinations of related issues. Existing flow conditions of the spillway and in the canal are investigated. Potential solutions are tested for their technical suitability. For some issues, numerical calculations are made for comparison with the experimental results. The model studies prove to be a useful tool in the rebuilding of the dam.
