Abstract: A numerical model has been developed to predict the three-dimensional flow character within low scope vertical slot fishways (VSFs). The modek solves the three dimensional Reynolds averaged Navier-Stokes equations, closed with the renormalised k-e turbulence formulations. The model employs the volume of fluid method to deal with the free surface. Results are presented for velocities and surface elevations utilising two fishway designs from prototype and laboratory studies. The respective data from the studies are direct compared to the numerical model predictions forming the basis of verification. The model is shown to predict critical design velocities, slot flow characteristics, flow recirculation and water surface elevations well enough to be useful in low slope VSF design.
