There has no matching water quality model reported in literature so far, although the hydraulic model of plain river network has been established by utilizing the celldividing method in the past decades. The feasibility and efficiency of the cell-dividing method used to solve water quality variables is demonstrated in this paper. A novel combined-cell water quality model based on cell-dividing method is proposed and applied to stimulating the water quality of Nantong river network of China, with results, showing the efficiency and accuracy of the proposed method. © 2011 IEEE.

Emergency management of sudden disasters needs a quick and efficient decision made by a group. The authors propose a visual discussion technique in group decision making of sudden disasters and construct the main technique process based on visualization theory. Based on this, Through the key techniques are researched and implemented. As for Multiagents in the discussion, they can obtain more accurate cognition of current sudden disaster situation and form efficient emergency predetermined plan by discussion and analysis in the short time.

Yamen channel is the important sea-route from Yinzhou Lake to Gaolan harbor in Zhuhai city through Huangmaohai Sea. Based on the recent hydrologic data and the seabed change, the numerical model is validated, and some advanced dredging plan for Yamen channel is simulated in the movement of tidal current and sediment, and the number of the sediment silting in channel is calculated. The result shows that there are some preponderance for the east channel in the tidal current and sediment, and the sediment is filling up in the mouth bars mostly. Moreover, the east channel has the potential to improve the channel standard, which can be developed firstly in the common condition. © (2014) Trans Tech Publications, Switzerland. Source

In order to show the calculated results from numerical model of tidal current easily, the Mapinfo software may be help for the graphics display as its outstanding function, and its relation database also storages and manages the mass data from numerical model expediently. GIS technology would be applied by a square cell in map, and the combined application is discussed in the stage of modeling, computation and demonstration, including the original data in AutoCad document, computed data in numerical mode and graphic data in the table sheet of Mapinfo software. This method is tested in Shizi Yang channel, and the model results can be shown and inquired, which can improve the efficiency of mathematic model in modeling, debugging and after-managing. © (2013) Trans Tech Publications, Switzerland.
