• Description:
• The service to be provided consists of a sediment echo sounder study of the water bottom of the German Inner Elbe in an approximately 2,700,000 m² river area (length of the Elbe section: 13 river km; width of the Elbe section: approx. 205 m) between Elbe km 508,000 and 521.00 including their preparation, implementation and follow-up. The services to be carried out serve to examine the water bottom with a focus on detecting any anomalies in the area of ​​the so-called remaining stretch of the Elbe, e.g. B. sand-covered head, base and bottom sills, i.e. control structures made of hydraulic stones in the riverbed lying transversely to the direction of flow. The services to be provided are carried out in cooperation with the WSV tracking system. The ESC At the same time, Elbe will continuously carry out a surface sounding of the water bottom and provide the contractor with the plausibility-checked data from the 2027 surface sounding for follow-up to the sediment echo sounder investigation. The services to be provided serve as a basis for the planning and prospective construction of the adaptation of the existing current control structures to reduce the strike line distance in order to improve shipping conditions in this area of ​​the federal waterway Elbe, which will be implemented in combination with hydromorphological measures to improve the water structure as part of the connection process to the overall Elbe1 concept. The aim of the project in relation to improving shipping conditions is one Stable fairway with a fairway depth FT of at least 1.40 m under GlW 20102 and a fairway width FB of, if possible, 50 m for GlW 2010. The services to be provided by the sediment echo sounder investigation are roughly summarized according to type and scope the professional one: Preparation of the sediment echo sounder survey, including: through the engineering planning of the longitudinal lanes, taking local conditions into account...
