Assessment of the deposition of polluted sediments transferred by a catastrophic flood and related changes in groundwater quality

Popis výsledku v původním jazyce

In the second half of the 20th century, industry and agriculture in the mountainous part of the Czech reaches of the Elbe caused much water pollution and a high suspended load. The Les Královstvi reservoir was built in 1914 to prevent floods endangeringthe cities downstream. Approximately 20 % of its volume has now been filled with polluted sediments. These could potentially be transported downstream and settled in the flood plain, and could thus also influence the quality of the ground water. The authors carried out a radar investigation to find where the sediments were located and to compute the amounts of sediments. Samples were taken for quality analyses. The re-suspension conditions in the reservoir during a catastrophic 500-year flood were computed using hydraulic methods, and the upgraded FAST 2D dynamic flow model was used to compute a map of the sediments settled in the flood plain. The movement of the pollution below the ground was then described using the MT3DMS model.
