Trier, Germany-based Geoka has release a new mapping technology claims to show the exact locations of areas that are affected by natural processes caused by heavy rain, i.e. landslides, mudslides, erosion, or underminings. The Ladwein Map of Geoka recognizes the areas of the earth’s surface where strong rain can result in damages.
The results of the Ladwein Map are said to be extremely precise. According to Geoka, if there are two properties next to each other, the map can clearly distinguish if natural processes are affecting only one of them.
Mudslides and landslides only occur at locations which the Ladwein Map discloses as a weak zone. River banks only collapse at places which are already weakened according to the Ladwein Map.
The areas which the technology of Geoka identifies as weak zones often seem to be very stable and safe to experts, but when holes are drilled and the material is analyzed, it is often found that the earth is stronger in these areas than elsewhere in the slope, which can lead to the false impression of security. In contradiction to conventional methods, Geoka’s SPIRS procedure states that these weak zones can collapse when there is sufficient strong rainfall.
According to Geoka, studies from four different universities have proven the results of the Ladwein Maps and feedback from engineers using the technology has been enthusiastic.
For example, in the area surrounding the devastating landslide in La Conchita, Calif., the Ladwein Map is able to show where and why the landslide took place.
The results of the Ladwein Map enable the residents of an area to assess their individual hazard potential more objectively, says Geoka. The Ladwein Map also enables effective preventive measures, therefore securing investments in buildings or infrastructure.
As the events arising from extremely heavy rains are mounting worldwide due to the climate change, the mapping information of Geoka offers much needed information on natural processes that can result in damages.
