Special Issue Information

Dear Colleagues,

Land subsidence is a worldwide environmental, geological, and global geohazard problem which generally covers a wide variety of engineering disciplines concerning theoretical research, fundamental studies, mathematical modeling, numerical simulations, and experimental investigations relating to any kind of current and emerging topics of land subsidence. Globally, freshwater demand is the leading cause of this problem due to the long-term overexploitation of groundwater and the increasing development of land and water resources threatens to exacerbate existing land-subsidence problems. To clarifying and characterizing the possible causes of land subsidence, various methods, including the soil consolidation theory, the geographic information system,  remote sensing, geological surveying, GPS, numerical modeling, etc., are used to analyze the cause of the aquifer compaction. Recent advances demonstrate that the implementation of the leading edge technology on land subsidence may give an insight into key solutions of the problems including the contribution of different aquifer systems to land subsidence, the hydromechanical behavior of aquitards, and the regional-scale simulation of coupled groundwater flow and aquifer-system deformation.

In this Special Issue, we encourage submissions focusing on leading edge technology on land subsidence, including the numerical methods, experimental investigations relating to any kind of current and emerging topics. This Special Issue welcomes high-quality submissions that, through theory and/or simulation with an emphasis on contributions which increase the basic understanding of land-subsidence and their application to mitigate land-subsidence problems. This Special Issue is also open to attract review articles which describe the current state of the art.

Potential topics include but are not limited to the following:

  • Analytical and numerical methods for modeling the behavior of land subsidence;
  • Field investigation of land subsidence;
  • Mitigation methods of land subsidence impacts;
  • Case studies of land subsidence;
  • Land subsidence innovative monitoring technologies;
  • Prediction of land subsidence;
  • Saltwater intrusion in coastal areas;
  • Other topics related to land subsidence.

In this article, the characterization of land subsidence with the spatial variability of soil formation and groundwater withdrawals in Choshui delta, Taiwan, is presented. Levelling surveys, borehole logging, multi-layer compaction monitoring network, multi-layer groundwater level monitoring network, and the electricity consumption of wells in the study area are adopted. Various factors, including the percentage of coarse-grained soil, percentage of fine-grained soil, length of average maximum drainage path, percentage of agricultural land use, electricity consumption of wells, and accumulated depth of land subsidence, are applied. Thematic maps based on these factors are established using geographic information system spatial analysis. A principal component analysis (PCA) is then employed to obtain the dominant factors for land subsidence. The results indicate that the largest subsidence rate is observed in the region that has both a high electricity consumption of wells and a large percentage of fine-grained soil. The PCA results reveal that the electricity consumption of wells is highly correlated with the accumulated depth of land subsidence. The first principal component is the acquired factor causing land subsidence, such as the excessive withdrawal of groundwater. The second principal component is the congenital factor causing land subsidence, which corresponds to fine sand, silty and clayey soils. Full article
