Abstract

The AA. have investigated the spatial and temporal characteristics of residual reclamation settlement of Chek Lap Kok Airport, Hong Kong. A total of 25 time series ENVISAT ASAR datasets, acquired between December 2003 and October 2008, were used to retrieve settlement rates and deformation history at high resolution and accuracy by means of advanced Synthetic Aperture Radar Interferometry (InSAR). The InSAR-derived results show a fairly homogenous and stable pattern in the sectors of the airport site corresponding to the two original islands of Chek Lap Kok and Lam Chau. In contrast, a relatively high spatial settlement variability was discovered within the majority of the reclaimed portion of the airport. A joint analysis of InSAR observations and geological materials indicates that the variability of the recorded residual settlement was highly correlated with the variations of thickness and pre-consolidation state of alluvial deposits below the reclamation
