Literatur Review: Perbandingan Berbagai Teknik Pemodelan Land Subsidence

Abstract

: The phenomenon of land subsidence is an event that can be identified by various methods. It is important to know in advance the hypotheses of the causes of land subsidence, such as the exploitation of underground water, exploitation of hydrocarbons, the occurrence of soil consolidation, due to geological factors, and tectonic activities. This article review is done by searching the data on the journal database. The keyword used in the article search is "Land Subsidence Modeling". The articles obtained are then compared. Comparisons were made to get the gist of the scientific article, especially the title, data used, modeling methods, land subsidence observation methods, and research results. Land subsidence identification can be done using soil and rock layer compaction analysis methods, underground water level change analysis, GPS measurements, Leveling, and time-series InSAR. Modeling of the land subsidence phenomenon is not enough with only geometric data from geodetic measurements, but it must also be supported by physical data related to the causes of land subsidence .
