Gravitational Effects on Groundwater Levels: Recent Research
Since writing my last two blogs (Groundwater Levels and Earth Tides - Part 1 and Part 2), I’ve received links to more recent research relating to semi-diurnal and diurnal groundwater level changes, including those caused by Earth Tides. I felt I should share these to end this series of articles. My thanks to Prof.
Earth Tides and Cyclical Groundwater Level Fluctuations (Part 2) Gravitational effects on Groundwater Levels
In my last blog, Groundwater Levels and Earth Tides - Part 1, I presented a six-month record of hourly groundwater level measurements from the Indian sub-continent showing daily cyclical variations of approximately 10 cm per day (Figure 1).
