Groundwater of Humid Tropical Hillslope
Description
In forest site, with comparatively steeper topography and a shallower soil layer, GW at the foot of the slope was responsive to rainfall due to the rapid subsurface flow from uphill. At the oil palm site, with comparatively gentle topography and a deeper soil layer, a different GW pattern responded more slowly to rainfall

We measured GW levels at three observation boreholes installed along each hillslope. Monitoring was carried out from August 2017 to December 2020 at Forested hillslope and from November 2018 to December 2020 at Oil Palm hillslope. Temperature and atmospheric pressure were recorded with a barometer (TD-Diver DI800, Van Essen; Delft, Netherlands); the latter were used to compensate for variations in measured pressure (DIK-615A-B1, Daiki; Tokyo, Japan).
