On x86_64-linux at -O3 with channel.f90 I get:
Deciding on smaller functions:
Considering inline candidate ddx.
Considering inline candidate ddy.
Considering ddx with 77 insns
to be inlined into sw
Estimated growth after inlined into all callees is +49 insns.
Estimated badness is 16177, frequency 0.00.
inline_failed:call is unlikely and code size would grow.

So I guess the question is why is this considered unlikely, given:
integer,parameter:: NSTEPS=6480
...
do istep=1,NSTEPS
time = istep*dt
! ------ interior calculations ------ !
dudx = ddx(u(:,:,mid))
dvdy = ddy(v(:,:,mid))
dhdx = ddx(h(:,:,mid))
dhdy = ddy(h(:,:,mid))
...
end do
