  • The percentage of analysis in which the parameter pesicides sum meets the threshold value

  • This layer contains the saveguard zones.

  • The percentage of analysis in which the parameter polycyclic aromatic hydrocarbons meets the threshold value

  • This map shows the extent and inundation depth of surface runoff in a 50-year heavy rainfall scenario [D60T50].

  • This layer contains the discharge points of the existing discharge structures (stormwater overflow basins, stormwater overflows and pumping stations with overflow)

  • Layer description: These climate parameters are part of the climate analysis for Luxembourg. The heat load PET (Physiological Equivalent Temperature) during the day (2 p.m.) is shown, which describes the “felt temperature”. The PET (Physiologically Equivalent Temperature) is a human bioclimatic index for characterising the heat load of humans, which combines statements on air temperature, humidity, wind speed and short- and long-wave radiation flows and is derived from a heat balance model. The PET has the unit [°C] and refers to a height of 1.1 m above ground (centre of gravity of the human body) and to the situation at 2 p.m. during a low-exchange radiation weather situation in summer. Explanation: The present geodata are taken from the regional climate analysis of Luxembourg (GEO-NET & LIST 2021) which was published with the report “KLIMAÖKOLOGISCHE SITUATION IN LUXEMBURG - Modellbasierte regionale Klimaanalyse / (La situation au Luxembourg en matière d’écologie climatique)” by the Administration for Environment. Source: -> https://environnement.public.lu/fr/klima-an-energie/changement-climatique/klimaanalyse.html -> https://data.public.lu/fr/datasets/klimaokologische-situation-in-luxemburg-la-situation-au-luxembourg-en-matiere-decologie-climatique/ Abstracts: The Luxembourg regional climate, which is formed during a low-exchange radiative weather pattern in summer, was investigated using high-resolution computer-based modelling. In total, the model area is described with 8,272,693 grid cells, with information on terrain height, land use, structural height and degree of sealing stored for each grid cell. The urban climate model FITNAH-3D according to Groß (1992) forms the basic framework for the modelling. The input data and model results are based on a horizontal spatial resolution of 25 m x 25 m. The model results are presented in maps. The model results are presented in cartographic representations of the nocturnal temperature field, the nocturnal cold air flow field (4 a.m. in each case) and the thermal load during the day (2 p.m.) and concretised in the form of a climate analysis map. The main product of the work process is a planning recommendation map with an associated catalogue of measures. On the one hand, the map makes visible the graduated need for action to improve thermal comfort in summer in all living/working and recreational areas (“load area”) of the population in Luxembourg. On the other hand, the planning recommendation map also assigns a value to all green and open spaces in the country ("compensation area") with regard to the climate-ecological functions they provide. Notes: - The geodata are only to be used in the context of the specific considerations of the above-mentioned report (e.g.: basic data as of 2018, specific meteorological framework conditions). - The composition of the layers is based on the corresponding maps from the above-mentioned report. Even though these layers can be combined with any other layers from other thematic areas in the geoportal, it should be noted that these representations can easily lead to misinterpretations. - Detailed explanations of this layer and the modelling methodology can be found in the sources mentioned above. - The assessments of the planning recommendation map are based on the climate-ecological functions without taking into account the concerns of other sectoral plans, i.e. the planning recommendation maps represent weighting material obtained from a climate perspective.

  • Watercourses with a significant risk of flooding

  • Risk assessment of the groundwater body regarding the failure of the good state in 2027.

  • According to the ordinance of april 16, 2021 of the sanitary protection zones of the Upper Sûre lake, the temporary storage of silage as mentioned in point 6.12.2. (Index 27) of the appendix II, compost (point 6.17.2., index 29, appendix II) and manure as mentioned in point 6.18.2. (index 30) of the appendix II on sub-parcels of the protection zones IIC and III that show a slope of less than 5% is allowed, respecting certain conditions. Citizens concerned can use the map to see which sub-parcels within the agricultural areas are affected.

  • The evaluation of the hydromorphological structure of surface water is made in two steps: First the method for the surface water development ability is applied. For this method the current structure of the surface water is analyzed for the different surface water sections. Constructing on the section-referred evaluation a total evaluation of the surface water development ability per surface water body takes place.
