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.
