Abstract

The present belongs to the technical field of reservoir operation, including following steps: selecting a dammed river to be tested, determining a study area in a riparian zone downstream of a dam, obtaining historical long-sequence water level data of the study area, and analyzing duration and amplitude variation ranges of a historical water level; setting a plurality of groups of flood waves according to the duration and amplitude variation ranges; establishing a riparian zone nitrogen transport and transformation numerical model to simulate a denitrification level of the riparian zone under different flood wave conditions; obtaining an A/T ratio value of one flood wave corresponding to a maximum value of denitrification capacity of the riparian zone according to results of all cases; and taking the obtained A/T ratio value as a threshold of a reservoir discharge hydrograph.
