Sink-hole modeling at a power plant site using microgravity data

A microgravity survey was conducted for detecting the sink-holes at site of a power plant.pits, man-made tunnels and canals were considered as topographical effects and werecorrected. to show the capability of the method two sites in a power plant have beensurveyed for existing areas which can be affected by sink-holes overnight.ground shakes due to the running facilities were also preventing us from taking a calmmeasurement.despite all unwanted factors at site, we could delineate the sink holes quite accurately.the depth of and the shape of these anomalies have been modeled by 3-d inversion ofmicro-gravity data
