This study is based on the use of geophysical investigations, in the case of a gravity method, in
order to identify underground cavities. In this study, we applied calculation of downward
continuation on a plane located underground and close to anomaly. This gravity value could
indicate the superior specifications of the anomaly in comparison with estimated results of the
calculated gravity data on the ground. By calculating the downward continuation of the gravity
data, features such as shape, size and depth of the anomaly would be determined. This method is
used for delineating subsurface cavities for instance, to avoid hazards of construction activity in
the vicinity of these areas. In this paper, the method is run using MATLAB programming and
eventually capability of this method and developed software are shown by applying on both
synthetic and real gravity data.
