INVESTIGATION ON IMPROVEMENT OF YANGTZE ESTUARY

Yen Kai, Yan Yixin

Abstract


The improvement of the Yangtze Estuary has attracted much attention in China. The fluvial processes of the estuary are rather complicated. The frequent move of sandbanks in the estuarine channels and the bar forming at the mouth give much trouble to navigation. Investigation on the guiding principles and schemes for the improvement of the Estuary has been carried out since 1958.Comprehensive field survey, laboratory experiments and numerical modeling as well as planning work have been done in the past 30 years with some preliminary achievement. A scale model study with horizontal scale 1:1600 and vertical scale 1:120 was conducted by the Nanjing Hydraulic Research Institute.
