Abstract

The present invention discloses a method and a device for determination of rainfall features, belonging to the technical field of hydrology. The method comprises the steps of: obtaining one rainfall rain-type feature matrix of each rainfall station in a plurality of rainfall stations of an urban area to be researched and a time feature matrix of the rainfall stations, and determining one sample rainfall type of each sample rainfall station through a first preset cluster algorithm according to the sample rainfall rain-type feature matrixes of the sample rainfall stations; performing fuzzy identification of the rainfall rain-type feature matrix of each rainfall station according to the sample rainfall type of each sample rainfall station, and obtaining one rainfall type where each rainfall station belongs to; performing statistics of relative time of the maximum rainfall happening of the rainfall stations after clustering through a second preset cluster algorithm according to the time feature matrix of the rainfall stations; and determining a rainfall type of the urban area to be researched according to the relative time of the maximum rainfall happening of the rainfall stations after clustering and the rainfall types where the rainfall station belong to.

Description

technical field [0001] The invention relates to the field of hydrology, in particular to a method and device for determining rainfall characteristics. Background technique [0002] In recent years, large-scale urban waterlogging disasters caused by extreme rainstorms have gradually increased, and the property losses caused by waterlogging disasters to urban residents have also increased. Therefore, analyzing and studying the rainfall characteristics of urban rainfall, so as to take countermeasures before the arrival of the rainstorm, to reduce the losses caused by the waterlogging disaster caused by the rainstorm, has become one of the problems that those skilled in the art are more concerned about. [0003] In related technologies, those skilled in the art usually set up a rainfall gauge station in an urban area in advance, and collect the rainfall of the rainfall gauge station in multiple rainfall events, and count the rainfall frequency of the rain gauge station within a ...
