Abstract

Hydraulic model studies of the Rusfors dam were previously made, the purpose of which was to examine the rebuilding solution for safe discharge of its design flood. In this work, two-phases computational fluid dynamics simulations were conducted to provide essential insights that help better comprehend the model test results. The hydraulic characteristics investigated in numerical modelling included the velocity profile, flow pattern profile and energy dissipation capacity.

Through analysis of the results obtained from numerical modelling and hydraulic model tests, the modified dam was found to have better energy dissipation capacity and sediment cleaning ability than the previous dam.
