Field surveys and sediment cores were used to estimate marsh erosion and land subsidence at Madison Bay, a well-known wetland loss hot spot in coastal Louisiana. Former marshes of Madison Bay are under about 1 m of water. Nearly two-thirds of the permanent flooding was caused by rapid subsidence in the late 1960s, whereas the other third was caused by subsequent erosion. Subsidence rates near M...

The rapidly developing urbanization since the last decade of the 20th century has led to extensive groundwater extraction, resulting in subsidence in Ho Chi Minh City, Vietnam. Recent advances in multi-temporal spaceborne SAR interferometry, especially with a persistent scatters interferometry (PSI) approach, has made this a robust remote sensing technique for measuring large-scale ground subsi...

Quasi three-dimensional (quasi-3D)modelling plays a major role in analysis of groundwater flow in multiaquifer systems and it can be an efficient tool for artificial recharge modelling. As the role of artificial recharge in groundwater management continues to increase, analysis of responses to artificial recharge has a particular significance. This paper deals with some practical aspects of the...

SUMMARY Subsidence of the land surface is defined as the vertical surface movement due to the removal of subsurface support. This paper presents the differential interferometric synthetic aperture radar (DInSAR) results derived from the data of various SAR satellites, such as ERS-1/2, Radarsat-1 and JERS-1, for subsidence monitoring. One of the limitations of selecting the suitable interferomet...

In recent years significant progress was achieved in SAR interferometry. In this paper we report on the potential of differential SAR interferometry to map land subsidence. After a presentation of the methodology the focus will be on feasibility demonstration and accuracy assessment. The theoretical considerations are verified with the selected cases Ruhrgebiet, Mexico City, Bologna, and Eugane...

This paper reports on the potential of differential SAR interferometry to map land subsidence. After a presentation of the methodology, the focus will be on feasibility demonstration and accuracy assessment. The theoretical considerations are verified with the selected cases Ruhrgebiet, Mexico City, Bologna, and Euganean Geothermal Basin, representing fast (m/year) to slow (mm/year) deformation...
