Stratigraphic Subsidence Monitoring

Causes of Depression in Taiwan

The occurrence of stratigraphic subsidence in the Taiwan began in the 1950s and was mainly distributed in the southwest plains of Taiwan. Mainly because the Taiwan economy began to take off in the 1960s, water demand increased rapidly. In the pursuit of economic development, large and concentrated use of groundwater, and excessive extraction of groundwater will have a significant impact on the formation subsidence. In addition to the southwest plain of the Changyunjia, northern Taipei, Yilan are all suffered from subsidence.

Multi-monitoring technology for subsidence

The company uses multiple monitoring techniques, including satellite positioning system (GPS), leveling, magnetic ring stratified formation subsidence monitoring and satellite synthetic aperture radar imaging (SAR). The results show that the subsurface analysis and analysis of the ground subsidence are carried out with the groundwater level monitoring data.

Stratigraphic subsidence monitoring

The company is enrolled by the Ministry of the registration of the surveying and mapping industry professional measurement company. With experienced field measurement team and internal data processing personnel, we can be efficient and accurate to carry put the works.

The site operation of Stratigraphic subsidence

Because of the different characteristics of the monitoring technology, the spatial resolution and the monitoring frequency are different. Therefore, it is possible to obtain high precision and high reliability monitoring results by using the different characteristics of multiple monitoring techniques, adopting complementary and interactive verification methods. The following figure is the company’s results of stratigraphic subsidence monitoring:
