Progress and Protects of China’s Estuarine Hydrographic Studies

The following are the major aspects of hydrographic studies of China's estuaries emptied into the sea: accumulated a large number data, develop widely the experiments of the physical models and mathematic simulations, and obtained much achievements of the estuarine tides, tidal current. salt-and fresh-water mixing, non-tidal circulation, wave, storm surge and sediment etc. aspects. The auth or suggests that we must improve the estuarine hydrographic observation station net, pay attention to the application of new techniques, such as the remote sensing and multi-discipline, strengthen the series observation for a long term, at the same time, pay attention to the basic theoretic study.
