河网水动力模型在防洪排涝工程建设作用评价中的应用

Application of Hydrodynamic Model for River Network in Evaluation of Flood Control and Drainage Projects

甬江流域地处浙江省东部,在2013年"菲特"台风严重受灾后,宁波市推进一系列干流防洪工程和平原排涝工程建设。为科学评价防洪排涝工程建设的作用,建立河网水动力模型,对工程建设前后重要平原的防洪排涝能力进行对比分析。结果表明,工程建设一定程度上提高了甬江流域整体的防洪排涝能力。

Yongjiang River Basin is located in the eastern Zhejiang province.The Ningbo government promoted a series of river food control and drainage projects after Typhoon“Fitow”affected the city in 2013.This study used hydrodynamic model for river network to research the projects’benefts by simulating the urban food situation.The results show that the construction of the food control projects have increased the Ningbo city food control and drainage capability.The research ideas of this paper can provide reference for other cities and regions to evaluate the benefts of food control and drainage projects.
