Geotechnical classification of sediments in accordance with DIN 18311 (2010) - Wet dredging work
Drill data evaluation 1-2m GOK
Description
The map of sediment classes for dredging works represents on a scale of 1: 250,000 information on the distribution of sediments of the same composition at the seabed surface 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 work in 7 classes (see legend). The map is based on sediment samples from the seabed surface to a depth of 0.2 m and strata descriptions of drilling at 0.2 m depth as well as in the above-mentioned depth areas, which were available in the German North Sea region until January 2013. These basic data are stored in databases at the BSH and LBEG, and data collected in the future will be integrated into them.
Dredging is necessary, e.g. if shoals created in waters by sediment rearrangement are to be removed in shipping lanes, material must be removed from the sea for coastal protection or construction purposes, as well as during pipeline or cable laying in the seabed. A basis for the commissioning and implementation of the corresponding work is the “DIN 18311 - General Technical Specifications for Works – Dredging”. This classifies the soil species to be found according to their nature in 10 classes, which are the basis for the evaluation of the sediment data on the seabed of the North Sea.
