Abstract

Contemporary area drainage dimensioning standards are presented in this paper. Hazards for drainage systems arising from climate changes are discussed and trends of changes in the precipitation structure are presented using the example of data obtained from Wrocław. The need for changes within precipitation scenarios is indicated for modelling overflow in channels and a research methodology and assessment criteria of the degree of reliability of the drainage system are proposed. Results are presented of an analysis of the operation of the rainwater drainage system in the Gaj and Tarnogaj housing estates in Wrocław – these were conducted using a calibrated hydrodynamic model in SWMM software. It was proved that the examined system does not meet the standards of PN-EN 752:2008, DWA-A 118:2006 and Merkblatt no. 4.3/3:2009 with regard to instances of flooding from channels and that adaptation to climate change is required.
