Subsoil - Sediment classes for dredging works in the German North Sea
Description
The map "Sediment classes for dredging works" presents information on the distribution of sediments of the same nature at the seabed surface down to a depth of 0.2 m and for the depth ranges 0-1 m and 0-2 m in accordance with DIN 18311 (2010) - Dredging works in 7 classes (see legend) on a scale of 1 : 250,000. The map is based on sediment samples from the seabed surface down to a depth of 0.2 m as well as layer descriptions from boreholes at a depth of 0.2 m and in the above-mentioned depth ranges, which were available in the German North Sea area until January 2013. Dredging works are necessary when, for example, shoals in waterways caused by sediment shifting have to be removed, material has to be taken out of the sea for coastal protection measures or construction purposes, and when pipelines or cables have to be laid in the seabed. One basis for commissioning and implementing the corresponding work is "DIN 18311 - General technical regulations for construction work - Dredging work". This classifies the soil types to be encountered according to their nature into 10 classes, which are the basis for the evaluation of sediment data on the seabed of the North Sea.
