A multi-scale CNN-GRU fusion model with stationary wavelet transform for 14-day ahead dam water level prediction
This study demonstrates a novel AI approach for critical hydrological predictions, offering significant enhancements in accuracy and operational efficiency for dam water level management. By integrating Stationary Wavelet Transform (SWT) with a multi-scale CNN-GRU fusion model, we achieve superior forecasting for 14-day ahead dam water levels, crucial for proactive water resource management and risk mitigation. This advanced model significantly outperforms traditional methods, providing robust and reliable predictions even in complex environmental conditions.
Executive Impact & Key Metrics
The implementation of this multi-scale CNN-GRU model with SWT decomposition delivers transformative benefits across water resource management. It enables precise 14-day ahead predictions, optimizing dam operations, reducing flood risks, and ensuring efficient water supply for communities. The model's improved accuracy directly translates to better decision-making, leading to significant cost savings from avoided damages and enhanced resource allocation. Our findings reveal a substantial uplift in predictive performance, underscoring the model's potential to revolutionize hydrological forecasting.

Enhanced Feature Extraction with Multi-Scale CNN
The study found that multi-scale CNN modules, especially in the slow and late fusion models (S3 and L3), significantly enhanced model performance. By utilizing various kernel sizes (1, 3, 5), the models effectively captured diverse features from the input data, ranging from fine-grained daily variations to broader temporal patterns. This adaptability allowed the models to extract more relevant information from both water level and multivariate features, leading to more accurate predictions.
Impact: Incorporating three multi-scale CNN modules in the multivariate input channel (S3 model) led to the best overall performance for 7- and 14-day ahead predictions, showcasing the power of multi-scale feature extraction in complex hydrological forecasting. This advanced feature extraction improved the model's ability to handle complex relationships in the data, offering a more robust predictive tool.
