Abstract

The background of this research is that Semarang has experienced the ground water level degradation in some areas. The method used in this research was time lapse microgravity during December 2003 to June 2004. The purpose of the research is to apply the microgravity method in determining the reduction zone of groundwater and alluvial plains Semarang using a 3D modeling by usingGrav3D program to identify the reduction of groundwater zone of alluvial plains in Semarang. The acquisition method of gravity wass done by using a Lacoste & Romberg gravitimeter G1158 and G1118 type equipped with alliod 100 to measure the gravity of each station and Lacoste & Romberg gravitimeter G508 type to measure the tidal effect of the gravity. The 3D modeling microgravity anomaly time-lapse effects of fluid dynamics is able to identify 9 groundwater reduction zones which is about, Ataqwa mosque, PRPP, Tugu Muda, Simpang Lima, Jl. Majapahit, Genuk, Tanah Mas, Tanah Putih, and around Sendangguwo area.
