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).
By diverting the water away, adverse consequences in areas at risk are prevented in the event of floods up to design event levels. E.g. the property or parts of the property can be protected by a wall that surrounds the building and keeps running surface water away from it. However, before constructing a wall, investigations…
Visualisation of specific hazard and risk at site (e.g. on maps, installed billboard at locations etc.) is an effective way of pointing out dangers to affected persons and institutions. Maps indicate the specific hazard and risk on site and could be provided on the municipality’s online portal for example. Easily understandable information for the interpretation…
Underground tanks work as retention basins. They can be integrated in the planning process of urban infrastructure in the underground like underground car parks.
Terracing is an ancient technology allowing the farming and building on steep and indented terrain. Farmland terraces consist of terrace platforms and terrace slopes or walls. In rural settings, the measure can reduce erosion and surface runoff by slowing rainwater to a non-erosive velocity. The measure is recommended for farmland with slopes >15°. However, terraces…
Traditional surface water drainage systems are often overloaded in case of heavy rain and thus cause flooding and damages. They can be developed further to “sustainable urban drainage systems” aiming on increasing their capacity e.g. when it comes to heavy rainfall and aligning them with natural water processes. There is a large collection of structural…
