Special Issue Information

Dear Colleagues,

In recent decades, various numerical and artificial intelligence codes have been adopted to simulate, calibrate, and predict hydrological and hydrogeological systems. Several models may lead to the same or similar results for each water system, and the main problem is selecting the superior model (single model) or using the multiple model discipline between them. The error of the model results and uncertainty of the input data, within and between models, are the main criteria for model evaluation.

Different approaches are applied to select a superior model or use multiple models (MMs) to generate optimal results from numerical and artificial intelligence models in different water systems, such as the prediction of runoff, rainfall, groundwater level, water contaminants and estimation of groundwater vulnerability and risk, land subsidence and so on. The main challenge is to determine whether single or multiple models are preferred for the simulation/projection of water systems. This Special Issue focuses on these approaches in hydrological and hydrogeological sciences, as follows:

  • Estimation of the uncertainty of artificial intelligence and numerical models;
  • Different approaches for efficiency evaluation of artificial intelligence and numerical models;
  • Superior model selection approaches for artificial intelligence and numerical models;
  • Different approaches for aggregate models or generating multiple models (MMs) of the artificial intelligence and numerical models;
  • Comparison of advantages and disadvantages of multiple models and superior models.

The selection of an appropriate ridge parameter plays a crucial role in ridge estimation. A smaller ridge parameter leads to larger residuals, while a larger ridge parameter reduces the unbiasedness of the estimation. This paper proposes a constrained L-curve method to accurately select the optimal ridge parameter. Additionally, the constrained L-curve method, traditional L-curve method, and ridge trace method are individually coupled with the system differential response curve to update the streamflow in the Jianyang Basin using the SWAT model. Multiple evaluation criteria are employed to analyze the efficacy of the three methods for correction. The results demonstrate that the constrained L-curve method accurately identifies the optimal ridge parameter in the actual model. Furthermore, the coupling of the constrained L-curve method with the system differential response curve exhibits markedly superior accuracy of simulated streamflow compared to the traditional L-curve and ridge trace methods, with the mean Nash–Sutcliffe efficiency (NSE) improving from 0.71 to 0.88 after correction. The constrained L-curve method, which incorporates the physical interpretation of the estimated parameters, effectively identifies the optimal ridge parameter in practical scenarios. As a result, it demonstrates superior usability and applicability when compared to the traditional L-curve method. Full article
