IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Morphological evolution of yangtze estuary on decadal-scale and its response to human interference

ABSTRACT
Previous studies indicated that Yangtze Estuary (YE) had experienced from sediment accumulation to net erosion in
submerge delta front within last half century responding to the reduction of fluvial sediment input caused by upstream
dam constructions. The present research analysis the morphological evolution of the entire estuary including tidal
channel within estuary and mouth bar area based on historical navigation charts and observed bathymetric maps.
Results indicated that the response to human interference (fluvial sediment reduction, engineering works) varied spatially.
The mouth bar region was still accumulating sediment after upstream sediment input declined while the tidal channel
within YE converted from deposition to erosion especially in shallow area.
