Article Synopsis
- Dry-wet cycles in sediments are important for greenhouse gas emissions, especially nitrogen oxide (NO), in both flowing (lotic) and stationary (lentic) aquatic systems.
- The study reviewed existing literature on how drying and rewetting influence NO emissions, revealing that sediment exposed during dry phases can significantly emit NO due to processes driven by water fluctuations and microbial activity.
- Although these NO emissions peak briefly during dry-wet cycles, their overall impact on global greenhouse gas emissions is not clearly quantified, highlighting a need for further research on this topic.
The parafluvial zone is frequently exposed to drying-rewetting cycles with critical consequences for the biogeochemistry of soil and sediment in river-floodplain landscapes. Upon restoration of the hydrological connectivity, substantial changes in biogeochemical processes are expected. The effects of water fluctuation on the magnitude of GHG emissions were investigated in the parafluvial zone of a restored river floodplain in Austria.
