The flow through the system was modelled with the FLOW-3D program. One of the pictures of the spillway crest with water is given below. The colours show the computed pressure. This is an instentaneous picture of the solution before convergence and a steady state is achieved.
The resulting rating curve is given below.
We want to thank Statkraft AS for funding the physical model study and for allowing us to publish the results.
