Self-protection against floods is becoming increasingly important. This is particularly true for the protection of residential buildings. The new information tool FLOOD.Bi can be used to determine and minimise the risk of flood damage to buildings. The Leibniz Institute of Ecological Urban and Regional Development (IOER) developed the tool together with the Saxon State Office for the Environment, Agriculture and Geology (LfULG) in the EU project STRIMA II. On 11 and 12 September, a team from both institutions will present the new online tool at the "Bauen Kaufen Wohnen", a fair on construction and real estate in Dresden.
