Improving groundwater storage change estimates using time-lapse gravimetry with Gravi4GW

Time-lapse gravimetry (repeat microgravity measurement) is a powerful tool for monitoring temporal mass distribution variations, including seasonal and long-term groundwater storage changes (GWSC). This geophysical method measuring in gravity (?g) potentially applicable to any system. Here, I present Gravi4GW, Python the site-adapted calculation of ?, conversion factor between ?g GWSC (also known as "topographic admittance"). Alpine catchments, particular, are ideal target sites they highly sensitive climate variations can experience significant GWSC, while often lacking infrastructure. Therefore, illustrate usage investigate detailed example an alpine catchment examine spatial effects depth assumptions. novel accessible designed be useful both planning data processing stages time-lapse gravimetric field studies.
