Calculation method of rainfall risk criteria in city

摘要

The present invention relates to a method for estimating the risk of heavy rainfall, which can precisely alert a dangerous situation to heavy rainfall concentrated in a short time, A method for estimating the risk of heavy rainfall by analyzing the amount of rainfall per hour and causing a storm warning and storm warning to be triggered, The process of defining the range of rainfall per hour that corresponds to the level of attention, boundary, and risk by analyzing the past actual damage histories, rainfall habits, and correlation analysis through frequency analysis, Based on the risk criterion for the amount of rainfall per hour derived through the correlation analysis, and performing a matrix analysis of the occurrence frequency of the disaster for a more specific time, thereby setting a risk rainfall criterion for each hour, And a method of estimating each heavy rainfall risk standard based on a rainfall observation point based on a range included in a thixotropic network so as to sufficiently reflect regional characteristics.
