In the embankment elevation map layer drawing module 040, according to the measured elevation measurement data of the embankment project, fixed-length embankment segments and corresponding elevation data are generated by interpolation at equal intervals along embankment lines and serve as the embankment elevation information, the section water level is encrypted to generate water level values at fixed intervals and serve as the section water level of the riverway along the way, and the section water level of the riverway along the way corresponds to the geographical position of the embankment elevation information. The method for obtaining the corresponding elevation data of the equally-spaced divided dyke sections comprises the following steps: simulating an upper edge curve of the embankment project according to the measured elevation measurement data of the embankment project, and acquiring a larger amount of elevation data of the embankment project as the elevation information of the embankment according to the upper edge curve of the embankment project. The upper surface of the dam project is arranged in a winding mode with a certain radian, and curve fitting is carried out according to actually measured elevation data of a plurality of measuring points arranged on the dam project. Because the data volume is large and the bending degree area of the embankment project is smooth, the curve obtained by fitting is very close to the actual radian of the upper surface of the embankment project. After the fitted curve is obtained, the elevation data of the embankment project which is multiplied by the original number can be obtained, and the graph layer information obtained after gridding is more accurate;
in the on-way water level information calculation module 050, the data in the water level database is trained by adopting a river network water level calculation strategy to obtain a hydraulic model corresponding to the basin. The distribution conditions of the river bed sections of each river basin are different, the hydraulic model considers the water levels, the flow rates, the flow coefficients, the main trough roughness, the left bank roughness, the right bank roughness, the Jiangxinzhou roughness, the local head loss and the section intervals of the sections at different moments and different spatial positions to calculate the water levels, but under the same conditions, the instantaneous water levels of the rushing rivers are different under the condition of different river bed sections (particularly turbulent river water under a flood state, the river surface can arouse larger wave flowers), and whether the water flow can overflow over the embankment project is the instantaneous water levels rather than the water levels under a stable state, so that the water level data measured by the hydraulic model trained by data in the water level database are more accurate.
And retraining the hydraulics model once every 1-2 years or after the section of the riverbed of the corresponding watershed changes. The section condition of the riverbed does not change excessively under the artificial condition, so that the hydraulics model is retrained every 1-2 years. And training different hydraulic models according to different flood frequencies. Under different flood frequencies, the influence degree of the riverbed on the instantaneous water level is different, the training is carried out according to the situation, and the obtained hydraulics model is more mature.
The submerged water depth map drawing module 060 corresponds to that submerged information is not marked in the fence area if the water level grid information is less than or equal to the dike elevation grid information at the same geographical position, compares the basic elevation grid information and the water level grid information in the corresponding fence area if the water level grid information is greater than the dike elevation grid information at the same geographical position, and does not mark submerged information in the corresponding area if the basic elevation grid information is greater than or equal to the water level grid information; if the basic elevation grid information is smaller than the water level grid information, marking inundation information in the corresponding area and determining inundation depth information according to the difference value of the basic elevation grid information and the water level grid information. The discrete data points are formed into a continuous image layer by gridding a plurality of information of riverway section water level and embankment elevation along the way respectively. And superposing the formed water level image layer and the embankment engineering elevation image layer to quickly obtain an area with the water level of the whole flow area higher than that of the embankment engineering. The program design is beneficial to quickly identifying the overflow part of the embankment project, and the calculated amount is small.
The existing method for predicting the flood submerging condition needs to calculate the flood overflowing amount and the elevation data of the ground and the building at the overflowing position, simulate the flood flowing condition and further calculate the submerging range and the submerging depth of the flood. According to the invention, the enclosure area with a smaller area is arranged, and when flood overflows over the embankment project, the water level at that time is the water level which can be reached by the enclosure area in the future (assuming that the water quantity is always in an overflowing state in a future period until the water level in the enclosure area reaches the water level in the flowing area), so that the water level of the area related to the flood can be obtained without calculating the overflowing water quantity. And the submerging range and the submerging water depth of the containment area can be known by comparing the water level with the elevation data of the buildings in the containment area.
And grading the submerging water depth information, wherein the corresponding marks of the submerging water depth information of different grades are different in color. The color markings can present the submergence range and submergence depth in a very intuitive form.
The flood risk prediction system further comprises a inundation area calculation module 070, which counts the number of water level information grids of the area marked with inundation information to obtain the inundation area. And when the submerging range does not cover the whole water level grid information, if the submerging range covers an area which is larger than half of the area of the single water level grid information, the submerging range is considered to relate to the whole water level grid information. The submergence range of the containment area can be predicted through a very simple calculation mode and a very small calculation amount, and flood condition early warning can be rapidly carried out on the containment area.
Flood risk prediction system still includes economic loss estimation module 080, will the surrounding area is divided into a plurality of township districts according to the villages and towns demarcation line, will the villages and towns are gone to divide into a plurality of economic value district according to building boundary or field boundary, and each economic value district has corresponding economic value information, according to inundate area with the economic value information calculation has marked the economic loss value in the region of inundating the information. The above programming allows for a fast estimation of the economic losses due to flooding.
While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention and should not be taken as limiting the scope of the invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.

A risk avoiding transfer method according to claim 9, wherein if the water level of the drainage basin is higher than the embankment project and the elevation data of the buildings around the drainage basin is less than the water level, the area where the buildings around the drainage basin are located is the area with risk of flooding, and if the water level of the drainage basin is lower than or equal to the embankment project or the elevation data of the buildings around the drainage basin is higher than the water level although the water level of the drainage basin is higher than the embankment project, the area where the buildings around the drainage basin are located is the area without risk of flooding.
