Abstract

The invention discloses a method and system for forecasting urban accumulated water by means of rainfall forecasts. The method comprises the steps that rainfall forecast information of a target city is obtained by means of a data interface of a meteorological department, and the rainfall forecast information is converted into rainfall duration data; simulation computation is conducted on surface runoff in the rainfall process and the drainage process according to the rainfall duration data and by combining urban drainage pipe point and pipeline data and geographical information data, and running status data of a drainage pipe network in the drainage process is obtained; calculation is conducted on the water accumulation process by means of a multi-source non-single depression accumulated water simulation method according to the running status data of the drainage pipe network and combination with surface elevation information, raster data of one surface accumulated water depth is correspondingly obtained by conducting calculation on each rainfall time step, all the raster data of the surface accumulated water depths of the whole rainfall duration process are obtained, and the surface accumulated water information data of each preset time is obtained, wherein the accumulated water information data comprises but not limited to the position, depth and range of surface accumulated water.

Description

technical field [0001] This application relates to the technical field of flood control, in particular, to a method and system for predicting urban water accumulation through rainfall forecasting. Background technique [0002] With the development of social economy and the acceleration of urbanization process, the urban planning is unreasonable, the construction of flood control and drainage capacity lags behind, and the vulnerability to waterlogging increases. Very serious. At the same time, the frequency, intensity and impact of urban waterlogging disasters are increasing day by day. Frequent urban waterlogging disasters have seriously affected the operation, management and safety of cities, and have become an important issue affecting urban public safety. [0003] In the current flood control work, the main ways to obtain urban water accumulation information are: setting up instruments in key historical water accumulation areas for real-time monitoring, flood control per...
