Abstract

This research aims to predict the irrigation indices of sodium adsorption ratio (SAR) and sodium percentage (Na%) using innovative machine learning (ML) techniques, including support vector regression (SVR) and Gaussian process regression (GPR). Thirty- seven groundwater samples were collected, and the primary investigation indicated that Ca- Mg-HCO3 and Na-HCO3 water types dominate the samples. The data is divided into two sets for training (70%) and validation (30%), and the models are tested with three statistical cri- teria, including mean square error (MSE), root mean square error (RMSE), and determination coefficient (R2). The GPR algorithm showed better performance in predicting SAR and Na% than SVR since it provided the lowest errors. The implemented approach proved efficient for the sustainable management of agricultural water.
