The Pearl River Estuary is one of the most complex river network areas in the world

which is located in the core region of Guangdong-Hong Kong-Macao Greater Bay Area. The dynamic and harmonious coexistence of sea

river

people and city is the goal of the Pearl River Estuary governance. Flood and drought disasters such as storm surge

salt tide and flood are prominent problems faced by the the Pearl River Estuary

and the construction of sluice at the estuary is feasible engineering options to these problems. In view of the comprehensive benefits of flood control

tide control and salinity resistance brought by the construction of sluice at the estuary

this article explores and studies the possible scheme for the construction of sluice at the the Pearl River estuary

calculates and analyzes the advantages and disadvantages of each scheme

providing references for future research on the construction of sluice at the Pearl River Estuary.
