Abstract : variation of flow condition caused by the multi - pur pose regulation schemes has been investigated on the basis of measured date in r iver model . flood - control of the upper river , operation of the power - station , saf ety of the bridge and power - station , navigation and evolution of the river are a nalyzed . a reasonable and feasible project alternative and the improvement measur ement are proposed 文摘:涪江潼南河段防洪整治是一項以防洪為主體的綜合性河岸整治工程,在平面二維數值模擬計算的基礎上再進行河工模型試驗,比較分析各防洪整治方案下潼南河段水流條件的變化,及其對上游防洪、河道、大橋、電站、航運、河勢的影響,提出合理可行的工程方案
