Hybrid Optimization: PSO-COO Algorithm
Our study introduces the PSO-COO algorithm, a novel hybrid optimization technique that combines Particle Swarm Optimization's (PSO) rapid initial search with Coati Optimization's (COO) robust local refinement and escape mechanisms. This approach is critical for overcoming suboptimal solutions and premature convergence in high-dimensional, nonlinear parameter spaces. By leveraging PSO-COO, we effectively fine-tune the parameters of both the GRU and ANFIS models, significantly enhancing their predictive accuracy and ensuring convergence stability for groundwater level forecasting.
Deep Learning: Gated Recurrent Unit (GRU)
The Gated Recurrent Unit (GRU), a powerful deep learning technique, is a cornerstone of the PCGA model. It excels at capturing complex nonlinear relationships and long-term temporal dependencies inherent in time series data, such as historical groundwater levels and meteorological variables. Unlike traditional models, GRU efficiently processes intricate hydrological data, allowing the model to adapt to subtle interactions between rainfall, soil moisture, evapotranspiration, and pumping rates. This capability ensures more accurate and robust predictions by effectively extracting hidden patterns.
Fuzzy Inference: ANFIS Model
The Adaptive Neuro-Fuzzy Inference System (ANFIS) serves as the final predictive engine within our hybrid framework. ANFIS uniquely combines the learning capabilities of neural networks with the reasoning ability of fuzzy logic. This synergy enables it to model complex, nonlinear hydrological relationships, gracefully handle uncertainty, and generate interpretable "if-then" rules. By taking the hidden patterns extracted by GRU as input, ANFIS translates these into precise and actionable groundwater level forecasts, making it highly suitable for diverse climate conditions.
Advanced Feature Selection: PSO-COO-XGBoost
To enhance model efficiency and prediction accuracy, we developed the PSO-COO-XGBoost algorithm for advanced feature selection. This is crucial given the high dimensionality of our input data, which initially includes 60 variables derived from five meteorological parameters across 12 lag times. PSO-COO-XGBoost efficiently identifies only the most impactful predictors (e.g., AVT, MAT, MIT, RH, and RAI at a one-month lag), reducing computational complexity and training time. This ensures the PCGA model focuses on the most relevant drivers of groundwater level fluctuations.

Case Study: Groundwater Level Forecasting in Iran
The PCGA model was rigorously tested for forecasting monthly groundwater levels (GWLs) in two critical regions of Iran: the Ardabil Plain and the Yazd-Ardakan Plain.
The Ardabil Plain, historically abundant in groundwater, has experienced a significant decline of 11.43m between 2003 and 2018 due to overexploitation. Accurate GWL predictions are vital here for effective water resource management, including artificial recharge, extraction regulation, and modern irrigation promotion.
The Yazd-Ardakan Plain presents an even more challenging scenario, characterized by extremely arid climate conditions, very low annual rainfall, high evaporation rates, and large seasonal temperature fluctuations. Despite these harsh conditions, the PCGA model demonstrated robust generalization ability.
In the Yazd-Ardakan Plain, the PCGA model achieved an MAE of 0.912 m, an NSE of 0.97, and a KGE of 0.96, significantly outperforming all other comparative models. This consistent high predictive performance across different environmental contexts highlights the PCGA model's suitability for reliable water resource management and decision-making in regions facing critical aquifer depletion and water scarcity.
