TY - JOUR ID - 21428 TI - Sink-hole modeling at a power plant site using microgravity data JO - Journal of the Earth and Space Physics JA - JESPHYS LA - en SN - 2538-371X AU - Ebrahimzadeh Ardestani, Vahid AD - Y1 - 2009 PY - 2009 VL - 35 IS - 2 SP - EP - KW - 3-D modeling KW - Microgravity KW - Sink-holes KW - Topographical effects DO - N2 - 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 were corrected. To show the capability of the method two sites in a power plant have been surveyed 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 calm measurement. 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 of micro-gravity data.
