abstract = "{Groundwater-level fluctuations represent hydraulic responses to changes
in groundwater storage due to aquifer recharge and drainage as
well as to changes in stress that include water mass loading and
unloading above the aquifer surface. The latter `poroelastic'
response of confined aquifers is a well-established phenomenon
which has been demonstrated in diverse hydrogeological
environments but is frequently ignored in assessments of
groundwater resources. Here we present high-frequency
groundwater measurements over a twelve-month period from the
tropical, fluvio-deltaic Bengal Aquifer System (BAS), the
largest aquifer in south Asia. The groundwater level
fluctuations are dominated by the aquifer poroelastic response
to changes in terrestrial water loading by processes acting over
periods ranging from hours to months; the effects of groundwater
flow are subordinate. Our measurements represent the first
direct, quantitative identification of loading effects on
groundwater levels in the BAS. Our analysis highlights the
potential limitations of hydrogeological analyses which ignore
loading effects in this environment. We also demonstrate the
potential for employing poroelastic responses in the BAS and
across other tropical fluvio-deltaic regions as a direct, in-
situ measure of changes in terrestrial water storage to
complement analyses from the Gravity and Climate Experiment
(GRACE) mission but at much higher resolution.}",
