FIGURE 8 Observed water level vs predicted water level graph: (a) weak
spatial dependence, (b) strong spatial dependence
It is known that the data during the period of November 2018 – July
2019 has weak spatial dependence. The water table map using the Kriging
technique from this period is displayed in Figure 9. Random groundwater
flow direction occurred, where it flows toward the outside of the farm
or into the existing stream in the North and South of the study area.
During June and July 2019, which is the transition into the high
rainfall season, the groundwater direction is started to change toward
the Northern stream.
