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…
Easily understandable and accessible information is important to raise flood risk awareness and support the implementation of private risk reduction measures. It can be made available as reading materials, for example in print products (handbooks, guidelines, brochures, flyers) or on online platforms. The products should be tailored to a specific target group, e.g. citizens, homeowners,…
Check dams act as barriers to swift creeks and gullies or usually dry pathways of concentrated surface runoff. They can be constructed in form of a sill or a step. The measure reduces the longitudinal slopes, serves the accumulation of surface waters and controls the velocity of the concentrated surface runoff during intense rainfall events.…
Through the vegetation of the soil substrate on the roofs water is retained and can evaporate. Two system of green roofing can be distinguished based on the level of maintenance: extensive green roof to an intensive green roof.
