In this work, an integrated satellite-based approach has been adopted using DINSAR and GPS observations to spatially delineate the subsidence-affected areas and cross-validate the subsidence rates using two collateral geodetic techniques. Multifrequency DINSAR using C- and L-band SAR data facilitates to monitor land subsidence scenario in totality. C-band DINSAR has been found particularly useful to identify slowly subsiding areas with a sub-centimeter level of precision. Furthermore, the initial hypothesis that land subsidence in Bandung Basin has been occurring due to excessive groundwater withdrawal has been established in this study. A predictive modeling approach has been adopted to estimate the rates of potential subsidence due to elastic and inelastic deformations of the aquifer and overlying strata in response to the lowering of groundwater level. © 2013 American Society for Photogrammetry and Remote Sensing.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Centimeter levels,Excessive groundwater withdrawal,Geodetic technique,Inelastic deformation,Initial hypothesis,Multi frequency,Overlying strata,Predictive modeling[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.14358/PERS.79.7.639[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
