Embodiment Construction

[0018] The method for simulating and predicting urban stormwater disasters provided by the present invention firstly modifies the SWMM data model, and embeds the SWMM calculation kernel on the GIS platform, thereby integrating the urban rainstorm management model SWMM and GIS into one platform, and then divides the sub-basin and obtains the information obtained by the model. Parameters are required, so that SWMM can directly use GIS data in the platform to simulate and calculate the water depth and drainage of the drainage pipe network, and realize the three-dimensional dynamic 4D simulation of the process of rising and falling of geographical accumulation of water and the three-dimensional visualization of the underground pipe network through the GIS platform.

[0019] As shown in Figure 1, the SwIvWI calculation kernel is embedded in the GIS integration platform for urban stormwater disaster simulation and prediction, and the spatial database stores and manages the access ...

Abstract

The invention provides an analog prediction method for urban rainstorm water disaster. The method comprises the following steps of: A, altering a rainstorm flow management model, and enabling the rainstorm flow management model to be accordant with a data model of a geographic information system; B, embedding a computing kernel of the rainstorm flow management model into the geographic information system; C, dividing sub-basins of a research region; D, acquiring parameters required by each model through the geographic information system; E, carrying out an analog computation to the rainstorm flow management model in the geographic information system; and F, achieving three-dimensional visualization according to a result of the analog computation. According to the analog prediction method for the urban rainstorm water disaster, the prediction efficiency of the urban rainstorm water disaster can be effectively provided; informatization and digitization of prediction of the urban water disaster are realized; quick, accurate, intuitional and effective forecasting to position, depth, time, duration of ponded water in the urban rainstorm water disaster can be provided; and a decision support for disaster prevention and reduction is provided.

Description

technical field [0001] The present invention relates to flood disaster prediction technology, more specifically, relates to a kind of simulation prediction of urban rainstorm water disaster [0002] method. Background technique [0003] Flood disasters have always been natural disasters that plague the development of human society. Flood disaster prediction is the foundation of flood control and disaster reduction. [0004] One of the core contents. At present, the management of water disasters utilizes geographic information system (GeographicInformation System, referred to as "GIS") technology, remote sensing technology (Remote Sensing, referred to as "RS") and Global Positioning System (Global Positioning System, referred to as "GPS") technology, as well as rainstorm prediction technology, flood forecasting technology, etc. to simulate and predict. However, this management method is relatively independent in completing various tasks, and does not integrate all technolo...
