Calculation on Tidal Ssediment in Changxingdao Sea Area;

Ecology characteristics in the island waters off Zhejiang Ⅰ. Species dominance of the zooplankton and ecology character of waters;

Assessment on environmental quality of Changxing Island in Dalian;

A hydrodynamical model for oilspill simulation in archipelagic waters with multiple open boundary conditions is set up and simulation/forecast tests in Zhoushan dingpu Port are performed.

The Shengli Chengdao sea area is located in the depositional system of the Yellow River delta, the original delta system has been eroded under the actions of wave and current, and the soft sediments are distributed on part of sea bottom.

A method,named as Recursive Method,has been applied for the calculation of submarine pipeline settlement in the Chengdao sea area of Shengli Oil Field,and the results from this method were compared with those from the Japan Code Method and the Limit Method,which are the two commonly used methods at the present.
