Lengthening periods between precipitation have been recorded and we can see a change in the distribution of rain over time. An increased number of these phenomena has also been confirmed by the IPCC. Due to this change in the redistribution of rainwater and the impact of high urbanization, sewerage systems are affected. The problem of a high number of impermeable areas is also associated with a high degree of urbanization. During torrential rains in combination with impermeable surfaces, the time of outflow into t...

At present, surface runoff represents serious environmental problems in the urban environment, causing adverse effects on socio-economic and natural systems. Surface runoff is a complex source. The creation of surface runoff is described by various hydraulic hydrological processes, from the impact of water on the surface to the mouth into the sewer network or recipient. The formation of the precipitation-runoff process depends on several factors. Land-use change is a key factor that significantly affects the quali...

Low impact development (LID) facilities are used to reduce the inflow of rainwater into the sewer network. Their use is welcome in highly urbanised areas where they decrease the network overloading during heavy rains. The aim of this paper is the implementation of LID facilities into the sewer network of the residential districts in cities. Subsequently, the assessment of their impact on network congestion at different load conditions will be done.

Stormwater presents a significant problem in urban areas, especially in large cities. The intensified formation of impermeable surface leads to suppressing permeable-vegetation areas and, subsequently, substantial changes in the area's hydrological, environmental, and ecological characteristics. By changing the city's spatial structure, there may be an increase in flood peak, volume of runoff, and rising pollution in urban stormwater. As a result of this phenomenon, the aquatic environment can be degraded by chang...
