Rain gardens as a way of retarding loss of waste water in urban green areas

Abstract

Rain gardens are one of the simplest and highly effective ways to manage rainwater. Founded in the ground or in a container, contrary to appearances, they resemble "ordinary gardens", However, thanks to carefully selected species of hydrophyte plants, they become a natural water reservoir, especially in urban green areas. In many European countries and the US, research and design of rain gardens is one of the most current tasks of spatial planning and landscape architecture. Also in Poland in recent years it has been decided to implement this type of hydrotechnical buildings in the urban landscape. They arise on the citizens' initiative or are part of the commune budget. Regardless of the source of funding, they form the core of activities related to adaptation to climate change and slowing down the loss of rainwater in urban areas.
