Rain is approaching, brace for heavy downpour. - Importance ofREADINESS for Heavily WATERLOGGED Precipitation
As the effects of climate change become increasingly evident, the potential for heavier rainfall events in Hesse, Germany, is a growing concern. While further research is needed to definitively prove that heavy rain is becoming more frequent, it is expected that this trend may continue.
To help residents prepare for such events, it is essential to adopt a proactive approach that focuses on awareness, avoidance of hazards, and effective planning.
One of the first steps is to avoid driving or walking through flooded areas. Flood waters, even shallow ones, can be deeper and swifter than they appear, posing severe risks to both vehicles and pedestrians. It is also crucial to stay away from electrical hazards, keep clear of downed power lines and electrical wires to prevent electrocution, and be alert to other dangers such as gas leaks.
Official road closures and safety warnings should be strictly adhered to, as roads may be closed to protect public safety. Knowing your property’s flood risk is also important, and residents are advised to consult local floodplain maps to understand if their home or workplace is in a flood-prone area.
Preparing your property beforehand can help minimise damage. This can include securing loose items, elevating electrical appliances, installing flood barriers, and ensuring proper drainage around buildings. Engaging with community resources and outreach programs can provide updated flood risk information and preparedness tips.
Urban flood mitigation often involves infrastructure and design measures guided by professional standards. For instance, buildings may be required to withstand flood loads and reduce damage during such events, as set out in standards like ASCE 7-22.
Expert Heike Hübenner from the Hessian State Office for Nature Conservation, Environment and Geology (HLNUG) advises that all cities and communities should deal with their respective situation and take countermeasures. Thomas Deutschländer, a hydrometeorologist at the German Weather Service (DWD), agrees, stating that this is currently being intensively researched.
The DWD defines heavy rain based on the amount of rain and the time period in which it falls, with a severe weather warning issued for more than 25 liters per square meter in one hour or more than 35 liters in six hours. If more than 40 liters are expected in one hour or 60 liters in six hours, the weather service warns of extreme severe weather.
The HLNUG offers special flow path maps to indicate local danger situations, and the city of Frankfurt warns against underestimating the danger posed by rapidly spreading water, particularly in tunnels, train stations, and basements. Entering flooded underground garages or tunnels is strongly advised against.
In addition, preventive measures such as installing a backflow preventer to prevent water from the sewer from entering the house, waterproofing windows and doors, and avoiding storage of valuable items in the basement can help protect homes and businesses during heavy rain events.
With increased awareness and proactive planning, residents of Hesse can better prepare themselves and their properties for the potential impacts of heavy rainfall and flooding.
- The science behind climate change reveals that heavy rainfall events might become more frequent, echoing the concerns in Hesse, Germany.
- Adopting an environmental-science approach to flood preparation can aid in understanding the risks related to exposure to carcinogens in floodwaters.
- As the Commission drafts directives on the protection of workers, it has been consulted on the risks related to exposure to carcinogens in floodwaters.
- Engaging in sustainable-living practices, such as proper weather-forecasting to anticipate heavy rainfall, can enhance one's preparedness towards flood events at home-and-garden.
