The assessment of the flows and the pollutant load discharged into the natural environment requires the installation of an adequate instrumentation. The knowledge of the hydraulic operation of the Combined Sewer Overflows (CSOs) is thus essential. We use 3D modeling (FLUENT) in order to understand the hydrodynamics in these works. Initially, the numerical results arising from 3D modeling of the flows in side storm overflows were validated in experiments in laboratory. In the second time, we applied the 3D modeling to the CSO of Clichy (France). Simulations enabled us to know the various shapes of water lines and the evolution of the overflow rate along the weir. The location of the free surface was done by means of VOF method. The analysis of the results of simulation was enabled to improve the instrumentation of this CSO.
