In the current study, an alternative diagram is introduced
to solve this problem. In some aspects, it is similar
to the multi-rectangular diagram (MRD) proposed by
Ahmad et al. (2003) and in other aspects to the piper
trilinear diagram in rectangular coordinates, proposed by
Ray and Mukherjee (2008). This new diagram can also be
used to represent the main processes that intervene in a
coastal aquifer and so allow the stages of saline advance
or withdrawal to be recognized by studying the evolution
of the hydrochemical facies.
