CFD modeling of a rain event on combined sewer overflow.

Stretching periods between precipitations have been recorded, and an adjustment of the dispersion of rainfall over the long run could be seen. An expanded number of these peculiarities have additionally been affirmed by the international panel on climate change. Due to this adjustment of the reallocation of water and the effect of high urbanization, the sewerage frameworks are affected. The aim of the work was to compare simulations of the rain event on the combined sewer overflow due to the reduced water quality recorded in the Trnávka River. The current state and the proposed building modification were compared because the current hydraulic and construction modification of the combined sewer overflow is absolutely not corresponding to the environmental regulations.
