Project
Land subsidence analysis using InSAR, hydrogeological coupled modeling, and machine learning: A case study in Hanoi, Vietnam.
Abstract
Land subsidence has been a long-standing issue in Hanoi, causing significant infrastructural damage in urban areas. This study analyzes land subsidence in Hanoi from 2017 to 2020 by integrating InSAR, hydrogeological (HM) models, and machine learning to assess the correlation between groundwater withdrawal and subsidence, as well as the impact of various controlling factors.
Sentinel-1 SAR data from ascending and descending orbits were utilized to assess and quantify subsidence rates via Persistent Scatterer Interferometry (PSInSAR) and decomposition analysis spanning from March 17, 2017, to December 20, 2019 in both vertical and horizontal directions in Hanoi.
By employing the HM modelling framework using the Richards' equation method implemented in the OpenGeoSys platform, the relationship between groundwater drawdown, aquifer recharge, and its impact on land settlement was assessed.
The results from the HM model through a case study of two hotspot regions, Tay Ho and Ha Dong, were compared to the displacement data derived from InSAR analysis for calibration processing in both vertical and horizontal displacement results.
A sensitivity analysis using non-linear machine learning techniques with the CatBoost model, optimized by the hybrid Grey Wolf Optimization-Whale Optimization Algorithm (GWO-WOA) method, helps provide a comprehensive understanding and assessment of the key drivers of land subsidence in the study area.
