Abstract: Variation of flow condition caused by the multi purpose regulation schemes has been investigated on the basis of measured date in river model.Flood-control of the upper river,operation of the power-station,safety of the bridge and power-station,navigation and evolution of the river are analyzed.A reasonable and feasible project alternative and the improvement measurement are proposed.

Key words: Tongnan reach of Fujiang, multi-purpose regulation scheme, flow condition

摘要： 涪江潼南河段防洪整治是一项以防洪为主体的综合性河岸整治工程,在平面二维数值模拟计算的基础上再进行河工模型试验,比较分析各防洪整治方案下潼南河段水流条件的变化,及其对上游防洪、河道、大桥、电站、航运、河势等的影响,提出合理可行的工程方案
