Technical Field

[0002] In recent years, with the rapid development of cutting-edge technologies such as remote sensing monitoring, artificial intelligence, and digital twins, flood control scheduling has gradually shifted from a traditional experience-driven model to a data-driven and model-driven model. Satellite synthetic aperture radar interferometry (InSAR) technology, due to its high spatiotemporal resolution for monitoring surface deformation, has been widely used in areas such as land subsidence and geological hazard identification. Meanwhile, the development of fluid dynamics simulation combined with high-performance computing platforms has made it possible to simulate flood evolution at a regional scale.
[0003] Despite significant progress, several key bottlenecks remain in practical applications. First, traditional flood control scheduling lacks effective modeling methods for underground seepage processes, making it difficult to convert surface deformation information into quantifiable seepage risk inputs into flood simulation models. This leads to inaccurate source term boundary condition settings, affecting prediction accuracy. Second, existing scheduling decisions are mostly based on static topology optimization of gate control strategies, failing to fully consider the coupling relationship between dynamic flow field characteristics and network topology, making it difficult to achieve precise, real-time basin-wide coordinated control.

Therefore, the invention is not limited to the specific embodiments disclosed below.
[0045] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.
[0046] Reference Figures 1-4 As one embodiment of the present invention, this embodiment provides a flood control scheduling method based on digital twins, comprising the following steps:
[0047] S1: Collect time-series satellite interferometry data, obtain the surface deformation rate and coherence coefficient, and calculate the leakage risk through a geological leakage model to generate a risk dataset.
[0048] S1.1: Based on time-series satellite interferometry data, an interferometric phase map is generated through phase unwrapping, and permanent scatterers are identified to obtain the surface deformation rate and coherence coefficient.
[0049] It should be noted that time-series satellite interferometry data is obtained by repeated orbital observations of the same area by synthetic aperture radar satellites. Time-series satellite interferometry data includes multi-temporal synthetic aperture radar image information, satellite orbital parameters, imaging time information, and radar equipment parameters.
[0050] Furthermore, the synthetic aperture radar image information is unwrapped using a minimum cost flow algorithm to generate an interferometric phase map. Permanent scatterer targets are screened using a dual standard of amplitude deviation index and phase stability. Based on the phase time series of permanent scatterers, the surface deformation rate is extracted through linear regression analysis. At the same time, the phase consistency of adjacent pixels is obtained to obtain the coherence coefficient. The interferometric phase map reflects the phase change characteristics of surface deformation. The identification of permanent scatterers ensures the stability of the monitored targets. The surface deformation rate quantifies the annual change of surface displacement, and the coherence coefficient characterizes the stability of the radar echo signal.
[0051] S1.2: Input the surface deformation rate into the geological seepage model to calculate the seepage risk, the expression is:
[0052] Q = k·e μ·ΔV ;
[0053] Where Q represents the leakage risk, k represents the bedrock permeability coefficient (0.2≤k≤0.35), μ represents the deformation sensitivity factor, and ΔV represents the surface deformation rate.
[0054] The specific process includes inputting the surface deformation rate into the geological leakage model, and then calculating the leakage risk using the bedrock permeability coefficient and deformation sensitivity factor. The bedrock permeability coefficient reflects the inherent permeability characteristics of the geological structure, the deformation sensitivity factor characterizes the weighting coefficient of the surface deformation on the leakage, and the surface deformation rate directly reflects the intensity of surface displacement change at the monitoring point. The bedrock permeability coefficient, deformation sensitivity factor, and surface deformation rate work together to generate a quantified leakage risk.
[0055] Furthermore, the pre-training process of the geological seepage model requires the collection of historical time-series satellite interferometry data, including surface deformation rate, coherence coefficient, and actual seepage event records. Surface deformation features are extracted using phase unwrapping and permanent scatterer identification techniques. An initial seepage risk calculation relationship is constructed by combining the bedrock permeability coefficient and deformation sensitivity factor. The deformation sensitivity factor is calibrated using historical seepage event data. The backpropagation algorithm is used to optimize the geological seepage model parameters to minimize the error between the seepage risk output by the geological seepage model and the measured seepage amount. Cross-validation is used during the training process to prevent overfitting. Finally, a pre-trained geological seepage model that can accurately reflect the mapping relationship between surface deformation rate and seepage risk is obtained.
[0056] S1.3: Calculate the leakage risk probability based on the coherence coefficient, the expression is:
[0057]
[0058] Where P represents the probability of leakage risk, C represents the coherence coefficient (0≤C≤1), and λ represents the attenuation coefficient (0.3<λ<0.7).
[0059] The specific process involves the coherence coefficient reflecting the stability and reliability of surface deformation monitoring data. The leakage risk probability ranges from zero to one, with higher values indicating more reliable monitoring results. The leakage risk probability is calculated using the attenuation coefficient of the coherence coefficient, which ranges from 0.3 to 0.7 and is used to adjust the influence of the coherence coefficient on the leakage risk probability. When the coherence coefficient is low, the surface deformation monitoring data has higher noise, and the leakage risk probability increases accordingly; conversely, when the coherence coefficient is high, the reliability of the monitoring data is enhanced, and the leakage risk probability decreases.
[0060] S1.4: Combine the surface deformation rate, coherence coefficient, leakage risk quantity, and leakage risk probability according to geographic coordinates to generate a risk dataset.

Each gate node corresponds to a feature vector set that integrates flood evolution characteristics and geological risk characteristics. After normalization and spatiotemporal alignment, a modulated node attribute set is formed. The node attribute set fully represents the comprehensive risk status and flood evolution trend within the control area of each gate.
