Problems solved by technology

[0007] The object of the present invention is to provide a method and system for deriving and designing rain patterns using the P&C method. By adopting the Pilgrim&Cordery method (abbreviated as "P&C method"), data cleaning is performed on the rainfall data of more than consecutive years of data years, and the "first rain" is excluded. Effect” is not obvious, and each rainfall is analyzed and screened, and the proportion of rainfall in each corresponding sequence period of multiple years of rainfall is statistically averaged to determine the average rainfall of each period of rainfall, and to calculate the initial rainwater closure. The short-duration rain pattern design solves the problem that the existing technology uses the most representative local rainfall process or the rainfall sample of the largest rainfall every year as the design rain pattern. The representativeness of the rainfall sample is not enough, and the design rain pattern cannot meet the "initial rain" pollution. serious technical problems

Abstract

The invention discloses a method and a device using Pamp; the invention discloses a method and system for deducing and designing a rain pattern through a C method. The use of Pamp; the method for deducing and designing the rain pattern through the C method comprises the steps of determining a designed rain pattern statistical sample, determining and sequencing the rainfall proportion of each time period of single rainfall, counting and averaging the rainfall proportion of the corresponding sequence time period of multiple rainfall, determining the rainfall proportion of each sequence, and deducing and designing the rain pattern. According to the method, data cleaning is carried out on rainfall data of more than continuous years of data years, statistics and average processing are carried out on rainfall proportions in corresponding sequence time periods of multiple rainfall in multiple years, the average rainfall in each time period of rainfall duration is determined, and a short-duration design rainfall pattern suitable for initial rainwater interception is deduced; the problems that when the local most representative rainfall process or a rainfall sample with the maximum rainfall every year is adopted as the design rain pattern, the representativeness of the rainfall sample is insufficient, and the design rain pattern cannot meet the design requirement for serious pollution of initial rainwater are solved.

Description

technical field [0001] The invention relates to the technical field of designing rain patterns, in particular to a method and a system for deriving a design rain pattern by using the P&C method, and more particularly to a short-duration design rain pattern that is suitable for initial rainwater interception and deduced by using the Pilgrim & Cordery method (referred to as "P&C method"). type of method and system. Background technique [0002] Rain pattern is the distribution process of rainfall intensity on the time scale. The rainstorm intensity formula expresses the law of the average intensity and the strongest period, but does not describe the process of the rainstorm intensity; and different intensity processes have the same effect on the runoff curve and the regulation and storage calculation. have an important impact. Therefore, the study of rain pattern is the foundation of modern urban rainstorm management as well as the establishment of the rainstorm formula, and ...
