ANALYSIS OF SUBSIDENCE USING CORRELATION BETWEEN TIME-LAPSE MICROGRAVITY AND GROUND WATER LEVEL CHANGES MODEL FROM GEOELECTRICAL RESISTIVITY DATA
In this research, we were measured time lapse microgravity in the last 4 month (April - August 2009) as rainy and dry season. The period is identified as ground water level lowering caused by high evaporation and as subsidence caused by high water consumption at confined water layer. In addition, we...

| Summary: | In this research, we were measured time lapse microgravity in the last 4 month (April - August 2009) as rainy and dry season. The period is identified as ground water level lowering caused by high evaporation and as subsidence caused by high water consumption at confined water layer. In addition, we measured time lapse geo-electric by sounding method to observe ground water level profile as above mention period. Geo-electric data is related with observe well as supporting data and validated with observe well. Furthermore, ground water level changes was detected by geo-electric method in order to be synthetic microgravity based on geo-electric model, then both anomaly are correlated with subsidence analysis. |
