There have been many cases of flooding in the Grand Duchy over the years.
On Monday afternoon, the revised up to date flood risk and danger maps were presented at the Ministry of the Environment, Climate and Sustainable Development. This project forms part of he European flood management plan of 2007.
Firstly, it is important to distinguish between floods and extreme weather situations, such as those experienced in Greiveldange last year.
In order to produce these maps, people had to check the archives for the trends of the last years, but also take into account what negative consequences are to be expected in the case of floods.
Injury too people and material damages are some of the considerations, but the impact on the economy, the environment and culture, including old buildings and museums, is also taken into account.
Flood discharge areas were also newly defined. Maps of the country now show which areas flood first and which flood the most, said Claude Schortgen. He explained that you could imagine this to look like a three-dimensional digital model.
This model is important for hydraulic modelling, as it can show the areas near shores, which are needed to calculate water levels.
Some 570 kilometres of water were measured - 94 of them in great detail. The maps can and should be consulted on Geoportail or at Waasser.lu said Minister for Environment, Carole Dieschbourg. She also emphasised the importance of receiving feedback in the context of an open procedure where people can share their opinions on the new maps using the feedback tool on Geoportail until 17 September.
Following last year's serious floods in Mullerthal and Greiveldange, among other places, a map will be added to reflect strong rains. You can fill in a questionnaire on the matter at flashfloods.lu
