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.
Rain gardens are small-scale vegetated gardens used for storage and infiltration. They are typically applied at a property level and close to buildings, for example to capture and infiltrate roof drainage. They use a range of components, typically incorporated into the garden landscape design as appropriate. Under the vegetation layer is a filter bed substrate…
All kinds of blue and green infrastructure in the settlement areas (rivers, river valleys, water reservoirs, natural and artificial wetlands, parks, squares, orchards, gardens, allotments, green street strips, grasslands and other) decrease runoff and increase retention capacity. Preservation of the existing elements and creation of new elements is a contribution to heavy rain risk management…
Flood early warning systems – if existing for the area – provide information that allow the actuation of emergency action (e.g. set up of a command unit, observation of risk areas) prior to the event and before damages occur. However, reduction of losses is possible only if early warning information are interpreted and assessed correctly,…
