The static gage pressure was measured at a location one duct diameter upstream of the 90[degrees] elbow that preceded the test section, using pressure taps configured as a piezometric
ring and connected to a micromanometer using pressure tubing.
The inclination of the pipe from the horizontal is recommended because it provides higher hydraulic head and lower piezometric
surface elevations at the back of the drains.

Figure 5 shows a groundwater level (piezometric
) map that was obtained for the study area using the data from 24 wells [11, 16].
Groundwater pumping achieved its maximum in 1988-1990, causing a lowering of the piezometric
level by approximately -10 to -12 m.
For the seepage index, we take the piezometric
tube level as an example.
In the solution process, piezometric
pressure [P.sub.rgh] = P - [rho]g x x is implemented instead of the pressure P, where x is the coordinate vector and g is the gravitational acceleration.

However, during the dry period, the piezometric
level of the wells lowers, while the salinity of alluvial waters increases.
New magma inputs reach the explosion chamber and press on contact breccia, which may have phreatic water arriving from the host rock fractures by means of the piezometric
monitoring from October 2009 to December 2010 showed fluctuations in mean groundwater levels ranging from 1.9 to 0.8 m deep (Fig.
