The incidence of extreme rainfall has increased in recent decades. This negative impact of climate change also calls attention to when dealing with the recovery and reconstruction of sewer networks. Slovak cities have built a combined sewer network, which in the event of heavy rainfall, is not able to fulfill their primary function. The pipes are not able to carry the large volume of mixed wastewater, and network overload occurs. This paper focuses on the assessment of individual collectors of the sewerage network...

By building artificial landscape elements, significant changes occur in the spatial structure of the city. The intensification of the formation of paved surface changes the hydrological characteristics of the area. Impermeable surface prevents the penetration of atmospheric waters into the soil horizon, which causes an increase in the volume of runoff, flood peak, and pollution loads in urban stormwater. As a consequence of this phenomenon, during heavy rains, a critical part of the city may be flooded. To reduce ...

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...
