The verification was carried out for two criterial rainfalls: the Euler model rainfall with occurrence frequency C = 3 years and an actual rainfall with C = 5 years. Two parameters: degree of flooding (DOF) and specific flood volume (SFV) were adopted to indicate potential system overloads. The simulations showed numerous outflows from the sewers, which means, that the investigated system needs adapting to climate changes. The causes of this should be sought in the too small diameters of the sewers and so in the insufficient hydraulic capacity of the sewerage system dimensioned in the past using methods which are inadequate today.</p>}, number={2}, journal={Periodica Polytechnica Civil Engineering}, author={Nowakowska, Monika and Wartalska, Katarzyna and Kaźmierczak, Bartosz and Kotowski, Andrzej}, year={2019}, pages={641–646} }
