FIGURE 10 Water table map and water direction line for the period of
August 2019 - December 2020
The water table maps for strong spatial dependence are displayed in
Figure 10. Color change during the period of August 2019 – February
2020 indicates that the water table is increasing during this period.
The shift in the water table also shows the direction of the groundwater
flow. Groundwater flow direction is perpendicular to the hydraulic head
(water table); therefore, during high rainfall season, it was flowing
from East to West direction and South East to North West direction
toward the Northern stream. It is known that the stream at the Southern
of the study area is relatively at a higher elevation compared with the
stream in the north of the study area. All information above shows that
water from the Southern stream was infiltrating and recharging
groundwater in the farm, and it was flowing toward the Northern stream.
