The xi_position and eta_position of rivers.nc input

[hpd14thu]

Hello everyone,

I have a question about the xi_position and eta_position of rivers.nc input.

I wonder the xi_position and eta_position refer to the internal grid or the rho grid(contains two more external columns).

If it refers to the rho grid, we can use i and j

But if it refers to the internal grid, we have to use i-1 and j-1.

Thank you and look forward for your reply!

It refers to i, j. The western-most u-point is at i=1.
