Abstract: | Purpose Although the water quality of the Rhine River in Europe has improved, contaminated sediments may still threaten fish populations.
This is particularly likely in Upper Rhine oxbow lakes, which are connected to the main river channel only at one end, except
for extreme flood events. The impact of such extreme flood events on the sediment toxicity has, however, not yet been investigated,
although numerous oxbow lakes exist with varying degrees of connection to their main river channels. |
