Monitoring and control instrument would have automatic water level recorders, vibrating wire piezometers
, reactivation of the existing water level observation wells, acoustic Doppler current profiler (ADCP) for a bathymetric survey, permanent discharge measurement station using horizontal acoustic Doppler profiler (H-ADCP), at Bukkur gorge (two numbers), CCTV cameras and telecommunication.
in the context of environmental investigations, Soil reconnaissance surveys as well as the installation of piezometers
or piezars will be carried out.
Additionally, the investigation included substantial field testing and monitoring including the installation of piezometers
, packer permeability testing, falling head permeability testing, pressuremeter testing, as well as down-hole and surficial electrical resistivity geophysical tests, it stated.

were installed upgradient and downgradient of OWTS flow paths for groundwater sample collection and monitoring.
For the groundwater sampling, two piezometers
were installed in the experimental plot and two in the control plot, at a depth of 1.
Every group of piezometers
was installed in between 2 laterals and along them (500 meters).
To measure pore water pressure development, pneumatic piezometers
and hydraulic piezometers
However, as most piezometers
available cannot cope with extremes of negative water pressure, the Bionics team is using even more specialised equipment.
In the interim, he said, testing devices called piezometers
have been installed in the core of the dam.
The screened depth, construction, and installation of these piezometers
were identical to the piezometers
in the lysimeters.
A survey campaign with three drillings (besides the already existing 24 drillings) and piezometers
was organized in order to plan the mining operation and investigate the geological and hydrogeological features of the gypsum body.
