Part I of this work deals with the acquisition, processing and interpretation of geophysical data acquired at the Floridablanca archaeological site, where remains of ancient Spanish buildings are buried. The techniques used in the survey are the geo-electric and ground-penetrating-radar methods. Use of inversion algorithms alone to interpret the data has not been conclusive to obtain a reliable model, since many uncertainties remained in the interpretation. Hence, in Part II we make use of forward-modeling methods to simulate the low- and high frequency electromagnetic responses of the structures to aid the interpretation. The simulations allow us to improve the model, regarding the location and size of the adobe walls making the buildings.
