Abstract
SUMMARY The simulated annealing method was applied to jointly invert gravity and resistivity data to obtain the geometry of the density/resistivity interfaces and subsurface electrical resistivity distribution. The results obtained from the inversions of synthetic data indicate that the joint inversion significantly improves the solution decreasing the ambiguity of the models. The method was applied to gravity and resistivity data carried out in Sinai (northwestern Egypt). The results obtained revealed the geometry of the water-bearing zone with thickness ranging from 80 to 180 m and of the limestone‐bedrock interface dipping northwards.
