Interconnection experiments

Interconnection experiments constitute one of the essential stages in investigations related to dam leakage. These experiments are frequently undertaken to obtain an irrefutable proof of the hydraulic connection between two water bodies, generally indicated or supported by previous investigations using one or several of the techniques described in the previous chapters. Briefly, the experiments consist of the injection in a water body of a determined amount of an appropriate tracer and the subsequent determination of its arrival at boreholes or springs located downstream.
