Study Of Regulate Lead On The Area From Zhuqi To Kegong In Minjiang River

with the rapid development of innovation and opening ,The economy of Minjiang River area developed very fast. But in Minjiang River drainage area, river networks are densely covered, influx are great and mountain floods happen casually in tycoon season. At the same time, as a result of human activity and natural matters etc, the falling and breakage of dams, bridges, docks happened frequently, which influence the economy development of Fuzhou and people's living in this area. For this reason, the comprehensive layout and integrated regulation of the area from Zhuqi to Kegong in Minjiang River are urgently needed, these measures will improve the natural conditions of Minjiang River and enhance the ability of flood controlling, shipping and drainage to insure the security of Fuzhou.Based on the experience of existing waterway regulation, using a great deal of field data, analytic data and existing research findings, the ragulate lead on the area from Zhuqi to Kegong in Minjiang River are studied by using physical models and schemes are recommended in this thesis. Additionally, the feasibility of schemes are further proved. In order to solute the problem of diffluence mouth's uppityness in the underneath boundary in physics model, the dissertation adopts numerical model to calculate the area from Zhuqi to Baiyantan ,and offer the physics model and the water level of Wenshanli and Kegong and the diffluence rate .at the same time, the dissertation compare the result between physics model and numerical model in different project.
