[en] The current study presents a new type of vertical slot fishway. The main difference of this trapezoidal fishway compared to the standard design of a vertical slot fishway remains in the separation of the pools into two zones: the migration corridor and the energy dissipation zone. The structure is first investigated in a physical model to optimize the training walls and slot geometry in order to avoid recirculation of the flow. Velocity and flow depth data from experimental flow measurements is later compared to the three-dimensional numerical model which provides a deeper insight into the flow field. The proposed design is found to avoid large vortices within the migration corridor. Moreover, uniform flow conditions are also found within the energy dissipation zone, thus providing an alternative corridor for fish passage.
