Abstract: In the lower reaches of the Huaihe River Basin, there is a large range of plain water network area, with staggered terrain and dense water system and polder. The Lixiahe Region in Jiangsu Province is its typical representative. Affected by regional rainfall, highland water enters the low-lying area quickly, and polder drainage water mix, jointly raise the rivers water level, cause floods, from the flood and waterlogging, both the surrounding highlands to low-lying polder caused by flood disaster, also have low-lying polder drainage to the polder itself and the upstream highland waterlogging flood disaster. In the face of the complex flood situation, the primary task is to construct a water network pattern that adapts to the location and terrain characteristics and meet the multi-destination drainage area so as to provide possibilities for multi-target utilization. This paper carries out water network planning with the help of resilience theory, seeks the combination of flood control and drainage management scheme with avoidance, recovery, adaptations and utilization, and discusses the realization method from the perspective of optimizing the structure and function of water network. The construction method of resilient water network driven by flood is studied, and the hydrological-hydrodynamic numerical model is established to evaluate the flood control and waterlogging capacity of the existing engineering system and compare the efficiency of planning measures. Regional flood conversion mechanism and existing problems are summarized, flood impact factors are analyzed, resilience object of rivers-lakes-channels-polder and connotation are identified, the scheme is planned, the scale of polder and canal system layout is controlled. The model calculation shows that the single measures can reduce the storage level of the water network and improve the drainage efficiency; the strong to weak effects ranking are river treatment. From the perspective of system governance and influence correlation, at least two combined measures are recommended; the comprehensive scheme significantly reduces the drainage water level of the rivers network. Compared with the current situation, the scheme can reduce DAHWL of the hydrological stations by 0.28～0.36 m, and the water network is good at flood control and drainage, meeting the design standard. On this basis, through the layout of rivers and lakes connectivity scheme, lakes are divided according to functional utilization, mainly by comprehensive utilization, flood detention and ecological restoration, realizing multi-functional coordinated and integrated development, and laying a foundation for multi-objective utilization such as water quality improvement. The study reveals the combination of planning measures such as remodeling of water network spatial pattern, storage capacity, improvement hydrodynamic and hydrological process regulation, which forms the main content of building resilient water network and provides a reference for water network governance. Resilience theory provides a new paradigm for plain water network planning and governance.
