20.500.12556/RUL-143810 Interdisciplinary design of a fish ramp using migration routes analysis The study presents several steps of a fish ramp geometry optimization performed with a 3D numerical model DualSPHysics, which is based on the smoothed particle hydrodynamics (SPH) method. The optimization process led to the design of a bottom ramp that is capable of providing suitable conditions for the migration of target fish species (Salmo truta, Phoxinus phoxinus, Cottus gobio, and Eudontomyzon vladykovi). Migration routes were determined as complex 3D volumes of fluid according to the simulated velocity field in various steady flow conditions. Including three categories of potential migration zones (rest, effort, and limit zones), migration routes were quantified in high detail in terms of the size and position of each zone, and in terms of the distance from a given fluid part to the nearest rest zone. The interdisciplinary approach of this study also led to the development of new tools for the DualSPHysics model, specifically suited to improve functionality in eco-hydraulics research. fishway river restoration smoothed particle hydrodynamics DualSPHysics ramp ribja steza renaturacija rek hidrodinamika zglajenih delcev DualSPHysics true false true Angleški jezik Slovenski jezik Članek v reviji 2023-01-12 13:58:53 2023-01-12 13:58:58 2023-02-13 09:41:37 0000-00-00 00:00:00 2023 0 0 12 str.
