Description

Technical Field

[0001] The present invention relates to the technical field of sponge cities, and in particular to a method and system for managing rainwater in high terrain of a sponge city. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can adapt to environmental changes and deal with natural disasters caused by rainwater like a sponge, and has good flexibility. It can also be called a "water-elastic city". Environmental changes include the management of stormwater and floods in various environments, including plain cities, basins, mountains and other terrains.

[0003] However, there is currently no specific management plan for high-altitude areas. For example, along high-altitude highways, railways, and around large dams, rainwater quickly gathers after rainfall due to its high terrain, forming a strong surface runoff. These runoffs may not only cause erosion and damage to the embankment itself, but also have an impact on residential areas and cultivated land along the line, leading to soil erosion and floods. At the same time, runoff often carries pollutants from the road surface, such as oil, heavy metals, rubber particles, etc., which further pollute the downstream water and soil environment and aggravate the damage to farmland and residential areas. In order to meet the requirements of sponge cities, there is an urgent need for a management plan for high-altitude rainwater. Summary of the invention

[0022] like Figure 1 As shown, an embodiment of the present invention provides a method for managing rainwater in high terrain of a sponge city, comprising: Step S101, obtaining the historical rainfall distribution and pollution index of the target area, establishing a stepped storage facility according to the historical rainfall distribution, and setting the filter material of the stepped storage facility based on the pollution index.

[0023] Specifically, for high-lying target areas that require rainfall resource management, such as highways, along railways, and around large dams, obtain meteorological big data from meteorological service structures such as local meteorological stations in the target area. Then, the average annual rainfall, average monthly rainfall, and the frequency of extreme rainfall events are calculated through statistical analysis software to conduct rainfall statistics in the target area. Among them, rainfall distribution statistics can also be performed for the target area, that is, the rainfall data may not be the same in the interval from high-lying areas to low-lying areas, and there are rainfall differences, which need to be counted separately. Secondly, obtain the pollution index of the target area, which can include pollutants on the road surface, such as oil, heavy metals, rubber particles, etc. According to historical rainfall, corresponding stepped storage facilities can be established. Among them, stepped storage facilities are combined with topographic features and storage facilities are selected near the main drainage path to maximize their rainwater collection effect. The capacity planning of stepped storage facilities should be based on rainfall distribution, and the minimum capacity required for each storage facility corresponding to different terrains should be estimated to ensure that more than 95% of rainfall events can be handled without overflow. After the step-type storage facilities are determined, the connection points between the storage facilities at different terrains should be connected by filtering materials, and the rainwater should be filtered through each level of storage facilities. For example, if the step-type storage facilities include 4 levels of storage facilities, the connection between the highest level storage facilities and the second level storage facilities can be primary filtered, such as using physical filtering materials such as gravel and coarse sand to remove large-sized solid waste; the connection between the second level storage facilities and the third level storage facilities can be intermediate filtered, such as using activated carbon, biochar and other high-efficiency adsorption materials to treat organic pollutants; the connection between the third level storage facilities and the lowest level storage facilities can be advanced filtered, such as selecting professional filtering media for specific pollutants, such as when the target area is frequently polluted by heavy metals, zeolite and zero-valent iron particles can be equipped, or when the target area is heavily polluted by oil or organic matter, activated carbon and biochar can be used for filtering.

[0024] In addition, for different terrains in the target area, the corresponding main pollutants may also be different. In this case, the pollutant concentration distribution of different terrains can be obtained, the main pollutants corresponding to different terrains can be determined, and corresponding terrain storage facilities and filtering materials can be set based on the main pollutants.

[0025] Step S102, obtaining the real-time rainfall in the target area, and comparing the real-time rainfall with the topography map to generate a corresponding rainfall topography map.

[0026] Specifically, when rainfall is detected in the target area, the real-time rainfall in the target area is obtained through the automatic weather station network, mobile weather radar, or satellite remote sensing data. Among them, the real-time rainfall includes data such as hourly rainfall in the target area and future rainfall trends. Then obtain the topographic map of the target area, which includes the different terrain distributions corresponding to the stepped storage facilities in the target area, and can also mark natural and artificial features, such as roads, buildings, green spaces, wetlands, etc., in order to better understand the impact of rainfall on these elements. Then the real-time rainfall and the topographic map are superimposed and analyzed, such as superimposing the rainfall distribution layer obtained by interpolation with the DEM terrain layer in the GIS software to generate a rainfall topographic map that comprehensively reflects the relationship between rainfall intensity and terrain undulation. If needed, auxiliary elements such as isohyet lines and water flow direction arrows can be added to the map to help intuitively show how rainfall flows with terrain changes.

[0027] Step S103, obtaining the initial water level of the stepped storage facility, establishing a terrain and water level model in combination with the rainfall terrain map, and adjusting the pumping rate and discharge rate of the stepped storage facility based on the terrain and water level model to keep the water level of the stepped storage facility within a preset range.

[0028] Specifically, the initial water level of each storage facility collected by the detection equipment is obtained, and the generated rainfall topography map is combined with the specific location and capacity parameters of the storage facility to create a three-dimensional model in the GIS environment. The three-dimensional model should further consider the impact of factors such as terrain, soil permeability, and groundwater flow on the storage facility. Then the water flow path is simulated, such as using a digital elevation model (DEM) to predict the natural flow direction of the water body after rainfall, and determine which areas are most likely to drain water to a specific storage facility, thereby determining the future water level of the storage facility. In addition, each storage facility has a corresponding ideal water level interval, which is the preset range. When the water level interval of the storage facility exceeds the preset range, there may be a risk of flooding. In order to keep the water level of the stepped storage facility within the preset range, the stepped storage facility is dynamically adjusted. Generally speaking, the higher the terrain, the more conservative the data setting of the preset range. The dynamic adjustment can dynamically adjust the inlet and outlet water of the stepped storage facility based on the real-time rainfall situation, the autonomous drainage capacity corresponding to each terrain, the future water level forecast, and the horizontal comparison of the water level of the stepped storage facility. The specific adjustment method can be, for example, when the main precipitation area is determined based on the rainfall topography map, the main precipitation area is the storage facility where flooding is most likely to occur. When the main precipitation area is a high-lying storage facility, the water release rate of the stepped storage facility is dynamically adjusted in combination with the estimated water level map output by the terrain water level model to keep the storage facility corresponding to each terrain within the preset range as much as possible; when the main precipitation area is a low-lying storage facility, the water release rate of the stepped storage facility and the pumping rate of the high-lying storage facility are dynamically adjusted in combination with the estimated water level map output by the terrain water level model, so that the storage facility can adjust the water level to both the high-lying and low-lying storage facilities at the same time.

[0029] Step S104, obtain the drainage demand corresponding to different terrains, determine the water quality requirement of the corresponding terrain based on the drainage demand, monitor the water level and water quality of the stepped storage facilities in real time, and determine whether the water level remains within a preset range and whether the water quality meets the water quality requirement of the corresponding terrain.

[0030] Specifically, based on the rainfall topography map in the above steps, the terrain features such as elevation and slope are identified, and the natural drainage capacity and drainage demand of each region are evaluated based on this information, including: analyzing the land use situation around each region (such as agricultural areas, industrial areas, residential areas, etc.), understanding the impact of potential pollution sources on water bodies, and thus determining the water quality requirements corresponding to different terrains according to environmental impacts. Then, by installing liquid level sensors and multi-parameter water quality analysis instruments inside each storage facility, water level and water quality data are collected in real time, and it is determined whether the water level remains within the preset range and whether the water quality meets the water quality requirements of the corresponding terrain, so as to intuitively determine whether the storage facility meets the requirements for rainwater storage and filtration. When the judgment result does not meet the requirements for rainwater storage and filtration, the corresponding alarm step can be triggered. For example, when the water level is not within the preset range, the corresponding level of flooding alarm level is determined based on the terrain of the storage facility where the water level is not within the preset range. Generally speaking, the higher the terrain, the higher the corresponding alarm level when the water level of the storage facility exceeds expectations. When the water quality does not meet the water quality requirements of the corresponding terrain, the filter material alarm will be issued for the storage facilities corresponding to the upper-level terrain, so that relevant staff can adjust and replace the filter material in time.

[0031] In addition, near the stepped storage facilities, stepped farmland can be designed according to the slope of the terrain. The layout of the farmland is combined with the storage facilities to guide and slow down the speed of rainwater runoff from top to bottom layer by layer, and ensure that the farmland area does not decrease. Each level of farmland can not only play a farming function, but also reduce the impact of floods on farmland by reasonably guiding runoff, thereby improving the stability of agricultural production.
