The necessity to adjust salinity in the sand analysis of the tidal river is raised and the method to check salinity and correct it is designed.

Numerical simulation of regulation for tidal estuary inlet;

Numerical simulation of flood on movable bed of a tidal estuary;

Effects of multi-bridge piers on flooding at tidal estuary;

Development of environmental decision support system for tidal river networks and its application to the Pearl River Delta;

In recent years, prompted by the urgent need of water pollution control, scientists and engineers on the Pearl River Delta have developed a series of flexible, accurate, and easy to use mathematical models especially suitable for tidal river networks; at the same time many new concepts and new techniques with academic as well as practical values have been advanced.

EDSS is a comprehensive software system for water quality management in tidal river networks in general and for the Pearl River Delta in specific.

Based on the hydrodynamics features,this paper builds a one-dimensional hydrodynamic mathematical model to simulate the variation of water level and flow rate in the tidal river network.
