id="par0005">A novel WNN forecasting model for ground resistance is proposed in this study.
id="par0010">A WNN trained in field measurements of soil resistivity and rainfall height.
id="par0015">It is tested in 5 different grounding systems with ground enhancing compounds.
id="par0020">Information about ground enhancing compounds behavior and performance is reported.
id="par0025">WNN model is proved to be an accurate tool for ground resistance forecasting.
