The Eiffel Tower (/ËaÉªfÉl ËtaÊÉr/ EYE-fÉl TOWR; French: Tour Eiffel, pronounced: [tuÊâ¿ÉfÉl] listen) is a wrought iron lattice tower on the Champ de Mars in Paris, France. It is named after the engineer Gustave Eiffel, whose company designed and built the tower.
A remote sensing technique that monitors the electrical resistance of soils in a restricted volume near the surface of an archaeological site; buried walls or features can be detected by changes in the amount of resistance registered by the resistivity meter.
In the soil, the Electrical Conductivity (EC) reading shows the level of ability the soil water has to carry an electrical current.ince the current flowing through the water is proportional to the concentration of dissolved ions in the water, the electrical conductivity can be measured. The higher the dissolved salt/ion concentration, the more conductive the sample and hence the higher the conductivity reading.
