There is a simple experiment to determine whether water is a magnetic field concentrator... simply wind an open-core inductor, and see if the value of the inductance changes when water is inserted as the core material. It does not.

Sure not. You are trying to replicate a huge and complex teluric phenomena inside the earth doing a small scale conversion. No way it will work. No one needs to use tap water in the above experiment to know it won't raise induction. This experiment does not prove anyting.
I say again, check magnetohydrodynamics and you will find the answer.
Also check gird pattern harmonic equations and how they relate to the earths magnetic lines and waterfalls.. You will find those in Bruce Cathie's books.

You see, many of the magnetic concepts taught in the school are wrong. If people are still not aware of the nulling point in the center of a bar magnet, then it's hard to discuss magnetism... But this is another story..
