Analysis of land deformation velocity using PSI ALOS PALSAR: Impact of coastal sedimentation to future Jakarta giant sea wall and waterfront city

In this research, we held study on land deformation at eleven watersheds that influence the sedimentation around Jakarta strait using PSI technique of ALOS PALSAR images. The result shows that land deformation at Jawa Barat province, especially Bandung city area gives significant impact to sedimentation velocity along eastern Jakarta strait, especially deep seaport as new economic zone of Jakarta Giant Sea Wall plan. We recommend to evaluate land conservation at Jawa Barat province and well management of artificial canals at eastern Jakarta strait to reduce the sedimentation.
