Executive Summary : | Groundwater depletion and mining are two important anthropogenic causes responsible for land subsidence at various places of the country. Differential interferometric SAR is a proven spaceborne technique, which can be successfully used for detection and monitoring of land subsidence much before the damage. Spaceborne DInSAR based analysis needs to be supplemented with ground-based measurements and in-situ observations for validation and characterization of land subsidence. Time series analysis and predictive modelling based on the causative factors would be beneficial to understand the nature of the deformation and scenario analysis. |
