Salt water wedge

Syscal, Promis

In coastal areas, the multiplication of groundwater pumping can sometime modify the natural salt water wedge and create salted water intrusion under land area. This intrusion may have a catastrophic impact on water resource, agriculture and industry (Werner et al., 2013).
To measure the extension of the salt water wedge in lands, electrical resistivity soundings, tomography or monitoring can be performed (Nowroozi et al., 1999, Rey et al., 2013, De Franco et al., 2009) with the Syscal and Syscal Switch range (Syscal Junior / Syscal Junior Switch / Syscal R1 / Syscal R1 Switch / Syscal R2 / Syscal Pro / Syscal Pro Switch).

The measurement of the soil electrical resistivity can also be performed using the Promis 10 Slingram type EM profiler that allows to measure the soil electrical resistivity with a high productivity.
