Layer showing the intensity of a modeled 50-year flood event. The intensity of a flood event depends on the water depth and the discharge.

Station serving to pump water up to a higher point.

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

scenario of the flood hazard map which shows the floodplain of a modeled 10-year flood event, as demanded by the floods directive 2007/60/EC

Layer showing the intensity of a modeled 100-year flood event. The intensity of a flood event depends on the water depth and the discharge.

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

Draft of the grand-ducal regulation regarding the safeguard zones around the Upper Sûre Lake (initial version)

Layer showing the different hazard zones or degrees of danger which affect humans, animals and goods. The intensity and the frequency of 10-year, 50-year, 100-year, 200-year and extreme flood events are combined in a matrix in order to express the degree of danger: the stronger the intensity and the more often the event occurred, the stronger is the hazard. One distinguishes between high, medium, low and remaining hazard.
