Damage from pluvial floods can be reduced by taking pluvial floodwaters into consideration in development and zoning plans and by establishing free pathways for runoff. This can be done by building regulations, e.g. by designation of special grassland or protection zones in risk areas in the zoning plan. Such zones serve for retention and a…
Organisational precautions as well as emergency measures are taken immediately after an event in order to guarantee the functionality of structures that aim at the protection against pluvial flooding (e.g. removal of debris and mud).
Surface runoff at meadows and pastures is attenuated compared to land under arable crops. Thus, a high proportion of meadows and pastures increases the retention capacity of agricultural used land and reduces the surface runoff. Therefore, the preservation of existing meadows against cultivation of crops or building activities especially in head water areas, on slopes,…
These solutions retain rainwater coming from infiltration. Everywhere where vegetation solutions are used for supporting retention, regardless of whether they are grass, trees, shrubs, plants used to create green roofs or green walls, the development of these plants can be supported by water absorbing geocomposite (GSW).
Pieces of land which have been zoned for development but are as yet undeveloped are declared to be unsuitable for building, or building permission is not granted.
Flood barrier systems consist of rails (angle brackets, which are installed next to the front door, for example) and dam beams, which are inserted into these rails. In the time of need this can be done quickly. The bottom of the dam bar has to be sealed. The suitability of the measure might be limited…
