Abstract
In fitting geoelectrical models to sounding curves from certain localities in Czechoslovakia, we applied “the Hedgehog” method. In the first step it uses the Monte Carlo procedure to find a successful model. Then, it goes systematically through the values of both the electrical conductivities and the layer thicknesses varying within given limits in the neighbourhood of the successful model previously found.
The inversion was effected for different types of magnetotelluric sounding curves corresponding to specific geological structures. From a large family of models tested by the Hedgehog procedure the best fitting and the most frequently occurring models were chosen. The direct problem was solved for their parameters and the resulting theoretical sounding curves were compared with the experimental ones.
