Question

topic that is simple, interesting, no one have done the research about it...

Answer 1

I suggest you find out what your advisor, principle investigator, or committee members interests in hydraulics are and the kinds of problems they have been working on. Find one of these that you believe you can make a contribution to and let that person guide you along. It worked for me.

Answer 2

go for effects of on ground dredged material disposal on ground water hydraulics.

or
water channel losses, techniques for minimizing the losses.
