  • Numerical model of eco-hydraulics flow - towards designing a nature-like fish pass [Elektronski vir]
    Novak, Gorazd, gradbeništvo/hidrotehnika, 1978- ...
    Worldwide, the overwhelming number of man-made barriers in fluvial systems has been identified as one of themajor causes of the reported staggering average declines of migratory fish. Fish passages, ... in particular close-to-nature types, which mimic the natural conditions of rivers, have been shown to help mitigate such problems. This study focuses on the characterization of the flow pattern in a bottom ramp. A 3-D numerical model DualSPHysics was successfully validated against experimental data and then employed for the simulation of turbulent free-surface flow in a straight channel with complex geometry. The effects of bed roughness, channel slope, and flow rate were quantified in terms of flow depth, velocity fields, area-velocity ratios, and turbulent kinetic energy. During the study, several new tools were developed, leading to new functionalities in pre-processing, solver, and post-processing which increase the applicability of DualSPHysics in the field of eco-hydraulics.
