Embodiment 1

[0050] Such as figure 1 As shown, it is a schematic flow chart of the method for predicting the degree of impact of stagnant water on urban areas described in this embodiment. The method described in this embodiment solves the technical problem that the degree of impact of stagnant water on urban areas cannot be accurately predicted in the prior art. . The method for predicting the degree of impact of stagnant water on urban areas described in this embodiment includes the following steps:

[0051] Step 101 , according to the data interface (API) opened to the public by the meteorological department, the rainfall information data of each area of ​​the city is obtained.

[0052] Preferably, this program can be set to analyze and obtain the rainfall information data of the target area in the city from the API of the meteorological department, and obtain the current rainfall intensity in the target area, and the current rainfall intensity in the target area reaches or exceeds the...

Embodiment 2

[0070] Such as figure 2 As shown, it is a schematic flow chart of the method for predicting the degree of impact of stagnant water on urban areas described in this embodiment. On the basis of Embodiment 1, this embodiment describes the water intake and The specific content of the simulation calculation of the drainage process. The method for predicting the degree of impact of stagnant water on urban areas described in this embodiment includes the following steps:

[0071] Step 201 , according to the location of the target area, obtain the surrounding water accumulation point location, water accumulation depth, water accumulation area, rainfall intensity and rainfall forecast information.

[0072] Step 202: According to the location of the accumulated water point, the depth of the accumulated water, the area of ​​the accumulated water, the intensity of rainfall, and the rainfall forecast information, and the historical rainfall data at the location of the accumulated water po...

Abstract

The invention discloses a method for forecasting a degree of influence of ponding on areas in a city. The method comprises the steps of: acquiring a ponding point position, a ponding depth, a ponding area, rainfall intensity and rainfall forecasting information around according to a position of a target area, comparing with historical rainfall data of the ponding point position, calculating similarities, carrying out sorting according to the similarities from bit to small, and according to a sorting sequence, acquiring one piece of historical rainfall data to use as forecast rainfall data of the ponding point position; by forecasting rainfall data, a drainage pipe point of the target area, pipeline data and geographic information data, carrying out analog computation on water entering and draining processes of a ponding point in the rain falling process to obtain ponding information data of a ground elevation reached when ponding in the ponding point is risen or faded away at each moment; and by a difference value of an influence elimination moment and an initial influence moment, obtaining influence time of the ponding point on the target area. The method disclosed by the invention solves the problem that the degree of influence of ponding cannot be accurately forecast only by historical experience; and accuracy of forecasting is promoted.

Description

technical field [0001] The invention relates to the technical field of urban flood control, and more specifically, to a method and system for predicting the degree of impact of accumulated water on urban areas. Background technique [0002] At present, my country's urbanization is developing rapidly, and among the many effects that follow, many factors have exacerbated the situation of urban waterlogging during the flood season. Urban waterlogging refers to the phenomenon of accumulated water disasters in cities due to heavy or continuous precipitation exceeding the urban drainage capacity. After the city enters the flood season, the impact of accumulated water on densely populated areas in the city is worthy of special attention. [0003] In recent years, serious urban waterlogging disasters have occurred frequently in many large and medium-sized cities in my country. Since 2000, there have been more than 200 urban waterlogging disasters of varying degrees on average every...
