Effect of leaks in dams and trials to detect leakages by geophysikal means,mera was also installed and was used to observe the infrared thermo-reflection of the downstream face of the dam during the leakage tests..The tests showed that even small leaks in sealing faces can lead to considerable water losses and extensive percolations of embankment dams.

Numerical modeling of self-potential anomalies due to leaky dams: Model and field examples,features a leakage zone, a seepage area and an earthen dam structure with physical properties similar to the field case considered below. We consider examples where the depth of the leak, the variation of anomalies with flow path, and the effect of a change in rock type within the dam are examined.

Modelling of streaming potentials and thermometrical measurements at a big laboratory channel,water discharge measuring sensor, 80 pressure transducers (piezometers), 20 electrodes of platinum, 25 electrodes of copper sulfate and five tensiometers were installed. All the sensors and electrodes were connected with an automatic PC-controlled scanner system..Several streaming tests were carried
