| Study on the Application of Nature-based Solutions in Planning for Urban Rain and Flood Resilience |

| Abstract: |
| The occurrence of urban rain and flood disasters is
closely related to climate change, land use, the spatial distribution
of flood control and drainage infrastructure. A large number of
existing facts indicate that the traditional method of planning that
relying solely on the municipal storm water pipe network has
high engineering cost and great difficulty in reconstruction, whose
actual effect is not ideal. The Nature-based Solutions (NbS), which
advocates minimal intervention to the ecosystem and combines
grey-blue-green infrastructure, provides a new planning idea for
urban rain and flood resilience. This paper adopts the research
method of "theory research + application case". Firstly, the way
of the application of NbS to planning for urban rain and flood
resilience is analyzed, with some planning thoughts for establishing
urban rain and flood resilience. Secondly, the paper uses MIKE
FLOOD Model to evaluate the flood risk of storm water. Finally,
combining with the characteristics of the application cases, the
concrete scheme that integrates NbS into planning for urban rain
and flood resilience is expounded, which is mainly based on dike
shoreline, water network and water level management. The results
show that planning for urban rain and flood resilience can be
feasible from the perspective of NbS. This paper aims to play a role
in promoting the implementation of NbS in China. |
