If you cannot take the time to describe what you are trying to model, and write down your questions in a legible, and organized manner, it will be very difficult that a soul in the forum spend their valuable time to help you.

I'm sorry, I thought this form you understand the question better.
However, my intention is to simulate an open channel where we find these values should be?
(1) for the first picture I've reduced the timescale factor and thus respond faster and finally converged. Is this true? and is 0.5 values to be used?and...
2. The second image: the values specified Where should I get? (Of course, to simulate open channel).

I suspect you want a free surface model but you are using particle multiphase. Have a look at the setup for the "free surface flow over a bump" tutorial for how to set up homogeneous free surface models.
