Mountainous River

Located in the north of Yun’nan Province, Shuifu wharf on the Jinsha River is an important port on and a key waterway along Yangtze River. The navigation channel is typically mountainous river, with its water area narrow, its trough winding, its surroundings complicated and a variety of cross-river or on-river projects as obstructions. To ensure the safety of navigation and port operation, the two methods of numerical simulation and prototype ship test are adopted to determine the water flow for restricted navigation in Shuifu wharf, i.e., 8000m3/s.

Interpolation Functions

The finite difference method was applied to simulate the morphological processes for a. navigation channel Mathematical equations were based on the SUTRENCH and PROFILE models proposed by L. C. van Rijn. The difficulties of treatment for bed boundary conditions were overcame flexibly by using the interpolation functions with high accuracy. The results obtained showed that the simulation is very suitable and able to be applied to practice problems.

Design And Construction

In view of the serious problem of siltation rate in Waterway Engineering, feasibility of the scheme is studied from the perspective of sedimentation on Pussur River of Bangladesh in this paper. Based on the analysis of the tide, sediment and topography of the waterway and numerical simulation, the characteristics of the flow movement in the project reach, the influence of the dredging channel on the flow and the siltation were analyzed. With the excavation of channel, due to the influence of dynamic changes and elevation difference, the siltation of the channel is about 0.70–1.79m/a near Inner Bar area, and is more severely in the upper section near Chalna. The implementation of the preliminary regulating structure can increase the velocity and reduce the siltation of the local section. Yet the siltation of the upstream and downstream sections may be added due to changes of flow with the structure. The further scheme should be optimized from the angle of increasing the velocity in channel and reducing the influence to upstream and downstream. The feasibility results can provide scientific basis for the design and construction departments.
