Germany's Soils Subsidence/Sinkholes Blog

Image
  According to the website Research Gate, Germany has an increasing number of sinkholes that have been developing since the 1980's within large-scale depressions and are distributed over different kinds of surface materials; clayey mud, sandy gravel alluvium and evaporites (salt).  GERMANY'S SOIL SUBSIDENCE/SINKHOLES Tiny shifts in the land surface across the whole of Germany have been mapped for the first time, with the help of the Copernicus Sentinel-1 radar mission. As you can see in the map below, land- surface deformation, such as subsidence, often happens because of changes that take place underground such as groundwater extraction, mining, natural consolidation of sediments and rapid urbanization. As Phys.org points out this ground motion can be a major threat, in both urban and agricultural areas, where continuous shifts over time can cause, for example, damage to buildings, roads, bridges, dykes, and other infrastructure, and can cause changes in the way surface water...

 Germany's Mass Wasting Risks RIVER FLOODING : Germany has a High level risk for river flooding. According to ThinkHazard, potential damaging and life-threatening river floods are expected to occur at least once in the next ten years. As you can see from the Map above the area colored red is a high risk which pretty much covers the whole country. The orange is for medium risk, then yellow indicates low. Out of all of the Mass Wasting Risks, for Germany this is the most significant one. LANDSLIDES; MUDSLIDES and ROCKSLIDES For Germany the risk of landslide susceptibility, mudslides and rockslides are classified as a medium level risk . According to Thinkhazard, this means from the current information available Germany has rainfall patterns, terrain slope, geology, soil, land cover and (potentially) earthquakes that make localized landslides an infrequent hazard phenomenon. As you can see above the risk for landslides in Germany on the map in yellow is very low risk , which covers t...
