The transient electromagnetic method (TEM) is sensitive to low-resistivity anomalies, making it potentially useful for water hazard monitoring, such as detecting water-rich zones during tunneling or mining. However, metal infrastructure (e.g., steel arch supports and rails) can significantly affect...
