Resumen

The paper presents results of numerical calculations of drag coefficientsof large sphericalsolidparticles. Several hydraulic cases were tested. The first one -the spheres were fixed at different heights above a roughbed of an open channel, the second one -the spheres moved along the channel bed and the thirdone -the sphere impacted and rebounded from a smooth surface. Finite Volumeand Lattice Boltzmann methodswere used for the simulations. The Particle Image Velocimetry (2D-PIV) was used to determine the velocity field in the open channel.
