Outflow area of the ÜG Elbe from 01.10.2018
Description
Outflow area of the ÜG Elbe 2018
The drainage area is part of the defined floodplain of the Elbe (ÜG). Its outer boundary is included in the maps for ÜG Elbe. The runoff area became valid with the public interpretation of the maps of the ÜG Elbe in the period from 1 October to 15 October 2018.
This area, in which a flat, directed flow occurs in the event of flooding, is essential for the unhindered discharge of the flood. The current shape of the runoff area was mainly determined in 2004 and depends in particular on the so-called runoff intensity (flow velocity > 0.5 m/s and intensity as a product of flow velocity and water depth > 0.5 m2/s). Obvious errors in the demarcation were corrected for the map presentation valid from October 2018 and the boundary of the drainage area was largely adapted to the lines of the existing flood protection systems. However, the experience from the major floods in 2006 and 2013 and analyses based on the updated 2D-HN model Elbe show that the outflow intensity is not sufficient as the sole criterion for a technically correct demarcation of the outflow area. A review and revision of the runoff area is currently underway. Once completed, an update will be made.
