The State Dam Administration of the Free State of Saxony intends to commission a terrestrial survey of approx. 17 km of Wesenitz from Porschdorf K8512 to the state border, as well as a further approx. 7.5 km of secondary waters and approx. 39 buildings.

A two-dimensional hydronumeric model is to be created for the Wesenitz river. The basis for this is the measurement of the water, structures and breaklines of the study area from river km 15 + 830 to 32 + 800. 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 the 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 extends along the Wesenitz, starting in the locality of Porschendorf directly behind the district road 8715 (river km 15 + 830) through the entire municipal areas of Dürrröhrsdorf - Dittersbach and the town of Stolpen to river km 32 + 800, as well as a further approx. 7.5 km of tributaries , including the structures. The Wesenitz usually has a bottom width of approx. 5 m to 10 m. The work to be contracted essentially consists of the inclusion of broken edges, cross profiles (plus edge strips each 10 m from the top of the slope) and structures on and in the water.
