Abstract: In the lower reaches of the Huaihe Rivers 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 quickly into the low-lying area, 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 exist 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 meets 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. Summarize regional flood conversion mechanism and exis
