Effect of temperature and drying-rewetting of sediments on the partitioning between denitrification and DNRA in constructed urban stormwater wetlands

•Both denitrification and DNRA decreased due to drying of sediments, but DNRA decreased more than denitrification.•Rates of both denitrification and DNRA increased with increasing temperature in slurries.•The relative increase in DNRA was more than denitrification with increasing temperature.
