[0005] 2. The traditional river water level measurement focuses on the water level and flow, especially the water level is the most closely related to the elevation of the embankment, so the water level mainly reflects the elevation value; while in the urban rain and flood inundated area, it is more concerned about the inundated area. How deep is the water, whether it can be opened to traffic, whether it can be walked, etc. Existing water level measurement cannot provide such information
[0006] 3. The early warning of rain and flood submerged areas is completely different from the early warning of flood
The rainwater inundation area in the city will be covered with municipal pipe network. When a heavy rain occurs, all the municipal pipe network will be flooded. In many cases, the rainwater inundation area is in a relatively low-lying area in the city, and the rainwater cannot be discharged from the drainage pipe network. In many cases, it will even backflow from the pipe network in the highlands to the pipe network in the lowlands, causing the drainpipe to become a water inlet pipe. When the rainstorm decreases, the drainpipe will start to function, but the flow channel is often not smooth due to the blockage of debris
When a heavy rain occurs, the traditional mathematical simulation to calculate the flow direction of the pipeline cannot accurately obtain the drainage speed when the water recedes, so the forecast and early warning time is inaccurate

Embodiment Construction
[0055] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0056] A method for early warning of urban rain and flood submerged areas is to provide a method that can actually measure and perform early warning for urban rain and flood submerged areas when heavy rain occurs.
[0057] Specifically, the present invention is a method for early warning of urban rain and flood submerged areas, including four functional modules:
[0058] (M1) Real-time observation module of water level in urban rain and flood submerged areas;
[0059] (M2) Sensor layout module for municipal pipelines in urban rain and flood submerged areas;
[0060] (M3) early warning indicator calculation module;
[0061] (M4) Real-time and early warnin...

Abstract
A method for warning of an urban flooded area comprises four functional modules: (M1) a real-time water level observation module in the urban flooded area; (M2) a sensor layout module for municipal pipelines in the urban flooded area; (M3) an early warning indicator calculation module; and (M4) a live and early warning plane output module. The method provided by the invention has the beneficial effects that: 1, during the flood, the city manager can verify the water level data of the flooded area and the water surface image, so that the measured data is more convincing and effective; 2, new water level measuring device and method in the urban flooded area are provided; and 3, a water withdrawal process line of the flooded area can be accurately predicted.
Description
technical field [0001] The invention relates to an early warning method for urban rain and flood, in particular to a method for early warning of rain and flood submerged areas in cities. Background technique [0002] Due to the poor drainage of urban low-lying areas during heavy rains, urban flooding areas are often formed. Passage of vehicles and personnel in the submerged area has great potential safety hazards. Therefore, it is necessary to measure the rainwater level and water depth of the flood inundated area during heavy rain, and publish the real-time water depth on professional and public websites. [0003] The traditional hydrological measurement and forecast methods are mainly for the measurement and forecast of the water level and flow process in the river, which is not suitable for the measurement and forecast of urban rain and flood inundation. Mainly manifested in the following aspects: [0004] 1. The traditional water level measurement method generally ado...
