COMPARISON OF THE PHYSICAL MODEL MEASUREMENTS AND COMPUTATIONS

摘要

The physical model, which was previously constructed for the evaluation of variousrnriver training alternatives, was used later for the verification of the numerical model.rnDetailed measurements were conducted on the physical model but after somernsimplifications. The numerical model, with basic equations which were obtained byrndepth-averaging and spatial filtering with turbulence model with Sub Grid Scalern(SGS) turbulent kinetic energy, was developed and verified with measurements onrnphysical model. The agreements between calculations and measurements werernbasically very good. However, the discrepancies exist in regions where basicrnassumptions of shallow water flow are disturbed.
