On the effective position of the free-fall solution and the self-attraction effect of the FG5 gravimeters

Autor: V Pálinkáš, Zhiheng Jiang, J. Liard

Publikováno v: Metrologia. 49:552-559

FG5 absolute gravimeters are the most accurate gravimeters available at present and have significant influence on the realization of a gravity reference through international comparisons of absolute gravimeters. The latter comparisons are the only wa

Locating and characterising groundwater storage areas within an alpine watershed using time-lapse gravity, GPR and seismic refraction methods

Autor: J. Liard, Laurence R. Bentley, Alastair McClymont, Masaki Hayashi

Publikováno v: Hydrological Processes. 26:1792-1804

Unconsolidated sediments in alpine watersheds can store glacier melt and snowmelt as groundwater, which helps sustain flow in mountain rivers during dry periods. However, the amount and distribution of groundwater storage in rugged alpine terrain is
