INHERENT DAMPING IN A PARTIALLY DRY RIVER

Abstract [en]

As intermittent power sources such as solar power and wind power gains traction in Scandinavia it is likelythat the electricity production will become increasingly dependent on hydro power as a buffer in times ofpower deficit from intermittent power sources due to weather conditions. Rapid changes in hydro powerdemand can rapidly change the flow conditions in proximity to the power plant. This paper aims to model thetransient behavior and quantify the inherent damping in a dry reach in proximity to the largest hydro powerplant in Sweden, with respect to production. A two-dimensional model solving the Navier-Stokes equationswith shallow water approximations was set up using the open-source solver Delft3D. The Manning numbers inthe reach was calibrated with measured steady state water surface elevation data. The simulation data wasthen validated with transient water level measurements. The results show that it's possible to calibrate theManning numbers using steady state water level measurements. The model also shows that it's possible tocapture the inherent damping and more transient behavior using Delft3D. The results can be used to bettermodel rivers without the need for resolving the upstream reach. The results can also be used forecohydraulical applications where the transient behavior is important
