Abstract Aiming at the problem of uneven ground subsidence in Wuhan, using Sentinel-1A SAR image data 36 scenes from July 2017 to June 2020, SBAS-InSAR was used extract information Wuhan. Influence factors such as urban construction, industrial development, rainfall, and carbonate karstification on subsidence. The results show that can effectively monitor There is a high correlation between sea...

We present a model of ground subsidence due to soil consolidation within coastal reclaimed land constructed in early 2001, Busan, South Korea. estimate 42 cm maximum during the period interferometric synthetic aperture radar observations, and 1 m or more subsidence, since end construction phase reclamation project. A hyperbolic was used relate three independent time series nonlinear behavior su...

Coal mining activities all over the world often introduce serious environmental impact to the local regions, such as the occurrence of land subsidence. Conventional subsidence monitoring is done by precision leveling and GPS surveying. However, recent studies show that differential interferometric synthetic aperture radar (DInSAR) is capable of monitoring land subsidence at sub-cm accuracy. In ...

High-resolution seismic reflections were used to map the upper 200 m along an approximately 22 km stretch of U.S. 50 highway in Reno County, Kansas, where natural and anthropogenic salt dissolution is known to threaten ground stability. Surface subsidence in this part of Kansas can range from gradual (an inch per year) to catastrophic (tens of feet per second), representing a significant risk t...
