1-D and 2-D zonal coupling algorithm for flow and sediment transport;

The model can be used for real time prediction of flow and sediment transport in multiple connected river channels and is suitable for the area where topography map is not sufficient.

of north branch of the Yangtze estuary was carried out and the flow-sediment characteristics of north branch was obtained.

When studying the host-branch transformation mechanism of the YaoJian channel (curving minute branch channel),the author uses the approximated model experiment to obtain the current of water motion characteristic of the curving minute branch channel.

In many situations the foodstuff machine and the packing machine is often needed to realize reciprocating continuously and especially in high automatic There are many such machines and each one has itself movement characteristic In terms of long time application and the writer analyses and discusses several; devices′s movement characteristic these devices can be controled easil

It summarizes the study and achievements on fluid mud definition, the formed mechanism and condition, the movement characteristics under the action of flow and waves and under the integrated actions of stormy waves and flow at seacoast and river mouth studied by scholars for a long time.
