! !MODULE: m3d - 3D model component
!
! !INTERFACE:
   module m3d
!
! !DESCRIPTION:
!  This modules contains declarations for all variables related to 3D
!  hydrodynamical calculations. Information about the calculation domain
!  is included from the \emph{domain.F90} module.
!  The module contains public subroutines for initialisation, integration
!  and clean up of the 3D model component.
!  The actual calculation routines are called in integrate\_3d and is linked
!  in from the library lib3d.a.

! if #MUDFLAT is defined, then the sequence of velocity equations

! and coordinate construction is made such that drying and flooding
425 426
! is stable. If #MUDFLAT is not defined, then adaptive grids with
! Lagrangian component are supported. Both, drying and flooding and
427
! Lagrangian coordinates does not go together.
