Abstract

The Electrical Resistivity Tomography (ERT) method was used in order to study the karstic system in Pedini area (close to the city of Ioannina, West Greece) νthat is related with sinkholes whereby the drainage of the surficial water was possible. The last five years floods are causing major problems in the area, since, the urbanization of the basin, in which the construction of a large highway is included, along with the increase of rainfalls produced a huge amount of water which the sinkhole was not able to drain any more. The geophysical survey showed that the depth of the sinkholes is about 30 meters, proving their limited capacity to drain the basin to the desired level. At the same time, a fractured zone of high porosity has been revealed in the vicinity of the sinkholes.This zone can be used as to increase the capability of the sinkholes to drain the flood water.
