Denitrification in a hyporheic riparian zone controlled by river regulation in the Seine river basin (France).

The article presents the result of the study concerning the denitrification and its development in a hyporheic riparian zone controlled by river regulation in the Siene River in France. It mentions that the riparian zone between the chalky hillsides and the river shows an important depletion of nitrate during the summer and autumn period. This depletion is attributed to denitrification which goes with a consumption of dissolved organic carbon and a decrease of redox potential. Moreover, it keeps the wetness of the riparian zone constant which allows the isolation of high temperature in summer and autumn as an important factor for denitrification.
