A figura mostra tubulações
subterrâneas. Da esquerda para a direita: duas tubulações de gás paralelas com um cabo
de telefone sobre elas. Os dois alvos à direita são um tubo de PVC e um cano de ferro,
enterrados a aproximadamente a mesma profundidade.
Esse perfil mostra dois canos
identificados sob uma laje de concreto.

Ground water surveys are one of the largest applications of the GPR,
because it is a rapid way obtaining information, of even a large
area, in regard to identifying ground water appearances.
Coarse sand- and gravel formations and
coarse moraines are the most significant ground water formation
areas. In these areas the GPR is usable. The ground water attempts
to settle in water conducting material almost in a horizontal level.
Because of this we can, as a rule of thumb, determine that, in the
GPR profile the ground water level is visible as a mirror image of
the ground surface topograhy. For the same reason the ground water
does not follow possible layer structures visible in the GPR profile,
but cuts them. These two facts are the most important criteria when
identifying the level of ground water on the GPR profile.
