Abstract

Abstract

The temporal and spatial variations of the net sediment flux overtopping the South Leading Jetty in the North Passage of the Changjiang Estuary are studied based on the field measured data.The results show that: (1) timely varying unit width net overtopping sediment flux has a good linear relationship at each field measuring stations along the South Leading Jetty; (2) sections of S4 to S7 jetty and S2 to S3 jetty are the leading sediment overtopping channel with extreamly high sediment transportation rate;and(3) Annual averaged net sediment flux overtopping the South Leading Jetty is about 296.6Mt, 62.24% of which happens in the flood season and 37.76% does in the dry season.
