Short summary
Precise leveling and InSAR are the useful geodesic techniques for monitoring the regional land subsidence caused by unlimited groundwater pumping. The main aim of this paper is to integrate the accuracy of precise leveling and the spatial resolution of InSAR with cokriging method for estimating the surface deformation. The results indicate this method is reliable for detecting the land subsidence and the characteristics of different aquifers influence land subsidence.

Short summary
Land erosion creates sediment particles that are redistributed from mountains to oceans through climatic, tectonic and human activities, but measuring the mass of redistributed sediment is difficult. Here we describe a new method combining gravity and photogrammetry measurements, which make it possible to weigh the mass of sediment redistributed by a landslide and a river in Taiwan from 2015 to 2017. Trying this method in other regions will help us to better understand the erosion process.

Short summary
During 1992-2013, pumping of groundwater caused large-scale aquifer-system compaction and land subsidence in the Choshui River Alluvial Fan (CRAF) in Taiwan. The subsidence has already endangered the operation of Taiwan High Speed Rail (THSR). In this paper, we introduce the multiple sensors monitoring system to study the extent of subsidence in CRAF and its mechanism, including GPS (Global Positioning System), PSI (Persistent Scatterer Interferometry), leveling and multi-layer compaction monito
