• Description:
• Creating continuity on federal waterways is a legal obligation and a high-priority task of the Waterways and Shipping Administration (WSV). The Federal Institute of Hydrology (BfG) provides expert advice on this. To address urgent ecological questions In order to answer questions about the continuity of large rivers, the BfG is carrying out a research and development concept "Establishing ecological continuity at barrages on federal waterways". An important part of this R&D concept includes questions about the function of Fish passes (FAA). Their construction is intended to enable good ecological status or good ecological potential in accordance with the WFD/WHG. The functionality of the FAA has so far been assessed directly at the site. In order to be able to assess beyond this assessment whether this also results in stable In order to establish populations of the fish cenosis, a model should be developed that shows the influence of continuity on fish populations against the background of the respective habitat offering. Population aspects, connectivity and habitat availability must be analyzed together become. In order to be able to calibrate and validate the model using real data, detailed data on the available fish-relevant habitats must be collected for two project areas. This tender includes the shallow water surveys of the bank area in the project area "Moselle". These are intended to close larger gaps between existing bearing data and state survey data. As part of the project, a multi-field echo sounder survey of the banks of the Moselle and individual weir areas is to be carried out. Manned and unmanned measuring systems are possible for recording. It is crucial that, in addition to positioning and orientation sensors appropriate to the measuring system, fan sounding systems are used that detect sloping banks or take measurements up to the Water stop line...
