[0200] The operation steps of this anti-buoyancy design water level prediction system and method are as follows:
[0201] Step 1: Multi-source data acquisition and standardization processing
[0202] The system utilizes a network of geological exploration equipment, meteorological monitoring equipment, and water level monitoring sensors deployed in the target area to collect geological and hydrological data on geological structure parameters, geotechnical mechanics parameters, and groundwater parameters; meteorological data such as precipitation, evaporation, and temperature changes; and real-time monitoring data on water level changes, pore water pressure, and soil moisture content. Subsequently, the system standardizes this multi-source heterogeneous data to generate a unified raw dataset for anti-buoyancy design flood level prediction, providing a standardized data foundation for subsequent data fusion and predictive analysis.
[0203] Step 2: Intelligent Data Fusion and Feature Extraction
[0204] The system employs wavelet transform algorithm to align the time-frequency features of multi-source heterogeneous data in the original dataset for anti-floating flood control level prediction, eliminating random interference. Then, based on Kalman filtering algorithm, it performs optimal fusion processing on the time-frequency aligned data to generate high-quality fused data for anti-floating flood control level prediction. Subsequently, the system extracts parameters such as geological permeability coefficient, storage coefficient, specific yield, groundwater runoff intensity, recharge, and discharge from the fused data, constructing a geological and hydrological characteristic parameter dataset, providing core input for trend analysis.
[0205] Step 3: Analysis and Prediction of Water Level Dynamics
[0206] Based on a dataset of geological and hydrological characteristic parameters, the system establishes a differential equation model for the dynamic change of groundwater level with groundwater level as the core state quantity, and uses the finite difference method for numerical solution to generate groundwater level dynamic change trend prediction data containing future time series water level prediction values.
[0207] Step 4: Training and Self-Optimization of the Intelligent Prediction Model
[0208] The system constructs a deep learning-based neural network model for predicting anti-buoyancy design water levels. Geological and hydrological characteristic parameter datasets and predicted data on dynamic changes in groundwater levels are used as training samples. The backpropagation algorithm is employed to optimize the neural network weight parameters, completing model training. A continuous performance monitoring mechanism for the prediction model is established, collecting real-time data on the error between prediction results and actual monitoring data. When performance degrades, a model retraining command is automatically triggered, and an incremental learning algorithm is used to fine-tune the model's parameters and optimize its structure.
[0209] Step 5: Real-time water level prediction and early warning assessment
[0210] The system inputs real-time monitoring data into the trained anti-buoyancy design flood level prediction model, calculates and generates predicted anti-buoyancy design flood levels and their confidence intervals for a specified future time period, forming complete anti-buoyancy design flood level prediction results data. Subsequently, the system calculates the absolute difference between the predicted water level and the engineering design flood level. It queries the preset warning level mapping table, automatically determines the warning level, and generates anti-buoyancy defense warning level data containing the warning level, risk degree, and recommended measures, thereby realizing the quantification and assessment of risk.
[0211] Step Six: Visualization and Decision Support
[0212] The system ultimately integrates the anti-buoyancy design water level prediction data with the anti-buoyancy design early warning level data, and generates an intuitive anti-buoyancy design water level prediction report through data visualization technology, forming a complete technical closed loop from data perception to intelligent decision-making.
