pattern flood
3.Flooding frequency has an increasing trend in Aksu River basin since 1987. 500 hPa circulation pattern of mixed flood in flooding season of Aksu River basin is characteristics of Xinjiang High ridge steady over middle and east parts of Tianshan Mountains, and north boundary of 5 880 gpm height line steady in /over Tianshan and North Xinjiang regions and west boundary extend to south Xinjiang closed to Pamirs Plateau, and subtropical low trough in central Asia.
4.The System skillfully takes advantage of the naturltopography and the eurved waterflowing pattern om the middle reach of the Mingjiang River, thus combining water-bifurcation, flood-diversion, sand-dredging and water-controlling as a whole gravity irrigation system, which guarantees the Chengdu Plain a land of abundance.
6.Abstract: This paper summarizes a series of tests and inve stigations on general layout,const ruction diversion,flood disposal,navigation,river closure,form of gate opening s ection,pattern of energy dissipation and scouring under sluice carried out for F eilaixia Proj ect by the Scientific Research Institute of PRWRC during the period from 1983 to 1998 and presents their major results.
