Research on Rainwater Infiltration

Abstract

Rainwater management in urban areas takes into account the needs of both the environment and people. The urbanization process has a dramatic impact on water retention hydrology, leading to increased volumes and outflow rates, filtration losses and subsurface flow. The creation of paved surfaces results in drainage of rainwater into a drainage network, which contributes to the reduction of natural filtration. The essence of the solution to urban hydrology lies in finding an acceptable compromise as an alternative solution for the drainage of rainwater from a territory. The subject of the research described in this chapter is a solution to water infiltration from surface runoff and a comparison of the results obtained from field measurements, laboratory analyses and numerical calculations. Such research is necessary mainly due to insufficient information in the technical standards of the Slovak Republic in the field of infiltration systems and rainwater infiltration, as well as solutions to them.
