The geodetically quality controlled data set we are creating is unique in the world and will help to gain a better understanding about the strength, progress and scale of urban flash flooding events\u201d, explains Dietmar Backes, doctoral researcher at the University of Luxembourg who coordinates the project.\u00a0<\/p><p>This large data base provides the key to establish a detailed digital model required to optimize urban flood modelling and push the accuracy and efficiency of \u00a0flood inundation predictions, which are currently conducted by RSS-Hydro. \u201cTo my knowledge this is one of the few occasions in which flood modelers have worked hand in hand with geodetic experts despite the apparent need for such a multi-disciplinary approach\u201c, says Dr <a href=\"http:\/\/www.rss-hydro.lu\/2018\/03\/about.html\" target=\"_blank\" title=\"\" rel=\"noopener\">Guy Schumann<\/a>, CEO and lead scientist at RSS-Hydro.\u00a0<\/p><p><figure class=\"wp-block-dev4-reusable-blocks-image  object-fit--contain\">\n    \n<img decoding=\"async\" class=\"wp-block-image unilux-custom-image-block\"\n                alt=\"\"\n            src=\"https:\/\/www.uni.lu\/wp-content\/uploads\/sites\/11\/2023\/07\/video_rtl.jpg\"\n                    style=\"object-position: 50.00% 50.00%; font-family: &quot;object-fit: contain; object-position: 50.00% 50.00%;&quot;; aspect-ratio: 16\/9; object-fit: contain; width: 100%;\"\n        loading=\"lazy\"\n\/>    <\/figure><\/p><p><strong>Support from the city and citizens<\/strong><\/p><p>RSS-Hydro, together with the University of Luxembourg, outlined the need of such a scientific study to the City of Dudelange chief engineer, who was eager to support this project and very much welcomed the idea that it would not only advance flood engineering studies but also be part of a PhD research project.<\/p><p>In the past, in particular in 2016, the study area has been hit by urban flash flooding. This study will provide a better understanding of the problem, support local innovation but also address the concerns of residence who suffer from frequent flooding.\u00a0\u00a0\u00a0<\/p><p>In addition, the study has been very well received by the community. \u201cThe support of the local population is key for the project we initiated. Although with brought support and all necessary authorisations from the local council, we still needed the agreement and understanding of the local residents, especially for the capture of the high-resolution data with laser scanners and drones. All of the enquiries and questions from the population were relatively easy to address and many critical voices became supporters of the project. We periodically receive emails from residents who provide photographic evidence of the flash flooding \u00a0that we can compare to our simulations\u201d, comments Dietmar Backes.<\/p><p><\/p><\/div><\/section>","protected":false},"excerpt":{"rendered":"<p>The University of Luxembourg and the start-up RSS-Hydro\u00a0are working together to optimise the prediction of flooding in Burange in the south of Luxembourg.
