Overview

Numerical modeling and field surveys reveal cave detection constraints in karst massifs, indicating that decreasing host rock resistivity reduces sensitivity.

Key Points

  • Cave detection via electrical resistivity tomography improves within resistive host rock, while lower host rock resistivity diminishes sensitivity.
  • Numerical study and extensive field surveys near Lunz am See delineate karstification features, validating subsurface models against speleological survey data.
  • Highlights that current diversion around cavities restricts ERT resolution, showing that synthetic data and structural models are essential for validation.
