21.3 Groundwater Level (GWL) Monitoring
Groundwater level (GWL) was monitored manually in some designated plots in each
location of the canal blocking (see GPS point in Fig. 21.1). PVC pipes for GWL
monitoring were installed at two positions of 0.6 and 1.8 km from the canal blocking.
At both positions, 6 pipes were installed perpendicular to the right side of the block
and 6 pipes to the left side of the canal blocking. The distance between each point of
observation in location #1 was 100 m. GWL monitoring was conducted regularly
every month. The monitoring position of 1.8 km is at the dome of the peatland area.
