Crux of the matter
The studies on managing the ‘Reiherstieg’ sluice in order to influence the oxygen conditions showed different outcomes. On one hand the oxygen supply will raise rapidly inside the ‘Reiherstieg’ channel. On the other hand the remobilization of sediments caused by the occurrence of higher flow velocities and the subsequent rise in the biological oxygen demand (BOD) will affect the content of dissolved oxygen that entered the ‘Reiherstieg’ by the new operating scheme, too.Additional studies on sediment consistency, amount, quality and time-varying remobilization have to be carried out to define the long-term effects the oxygen conditions in the investigation area.
