Statistical High Flow Calculations
Statistical high flow calculations for 24 dams in Sweden
Description of the project:
The project comprised calculation of Q100-floods for 24 dams, and dam break calculation for two dams.
Determining the Q100 (Class – II flow) for 24 dams owned by Fortum.
- The flow was determined by statistical analysis of measured flows;
- Dam break calculations of Jösseforsen Dam;
- The dam break hydrograph and flow levels where calculated for Jösseforsen Dam;
- Dam break calculations of Stora Jangen Dam;
- The dam break hydrograph and flow levels where calculated for Stora Jangen dam.
One difficult and time consuming part of the flow calculation was accounting for the 19 bridges that lie in the flood path.
