Partitioned parallel computing method and system for dynamic flood risk map

Abstract

This invention provides a method and system for parallel computation of dynamic flood risk maps. The method includes: matching a target first-level zoning scheme based on real-time meteorological forecast information of the target area to divide the spatial computation domain of the target area into multiple first-level computational zones, and performing parallel simulation calculations of flood risk factors on the multiple first-level computational zones; if an abnormal real-time computational load index value is detected in a target first-level computational zone among the multiple first-level computational zones, then matching a target second-level zoning scheme to decompose the target first-level computational zone into multiple second-level computational zones, and switching the simulation calculation for the target first-level computational zone to parallel simulation calculations of flood risk factors for the multiple second-level computational zones; generating a flood risk map of the target area based on the simulation calculation results of each first-level computational zone and each second-level computational zone. This invention achieves low-cost, fast, stable, and reliable parallel generation of dynamic flood risk maps.
