The State Dam Administration of the Free State of Saxony intends to carry out a terrestrial survey of approx. 18.7 km of the Gottleuba from Pirna Bridge Mühlenstraße to the downstream dam Gottleuba as well as a further approx. 5.5 km of tributaries, approx. 15.5 km longitudinal structures and approx. 38 bridges plus substructures and culverts to be commissioned.

A two-dimensional hydronumeric model is to be created for the Gottleuba river. The basis for this is the measurement of the water, structure and breaklines of the study area from river km 2 + 400 to 21 + 100. The primary aim of the measurement is to produce a basic plan (digital location and elevation plan) for the water level position calculation, which relates to hydraulically relevant structures of the water hose are concentrated and consist of height-occupied, neatly connected line elements and possibly points.

The editing u. The study area stretches along the Gottleuba from Pirna Höhe Bridge Mühlenstraße (river km 2 + 400) through the municipalities of Pirna, Dohma and Gottleuba - Berggießhübel to below the Gottleuba dam (river km 21 + 100) and along another 5.5 km of tributaries and 15.5 km of longitudinal structures including the structures. The Gottleuba generally has a floor width of approx. 5 m to 10 m. The work to be contracted consists of recording breaklines, cross profiles (base width plus edge strips each 10 m from the top of the slope) and measuring structures on and in the water. Furthermore, the existing inventory measurements of the Gottleuba from the mouth into the Elbe river km 0 + 000 through the city area of Pirna to the bridge Mühlenstrasse river km 2 + 400 are to be integrated into the documents.
