Schematic illustrations of forced-gradient tracer experiments performed in the Experimental Hydrogeological Park (Telangana, Southern India): (a) convergent tracer test between two boreholes, (b) push and pull phase during push-pull tracer experiments.
Schematic illustrations of forced-gradient tracer experiments performed in the Experimental Hydrogeological Park (Telangana, Southern India): (a) convergent tracer test between two boreholes, (b) push and pull phase during push-pull tracer experiments.

Highlights

  • Increasing investigated volume in push-pull and convergent tests shows transition from independent to connected channels.
  • Multi-scale tracer tests may contain information about correlation length in fractured rocks
  • Non-reversible advective process appears more important in push-pull tests with increasing volume of investigation
