What is MOHID
MOHID is a three-dimensional water
modelling system, developed by
MARETEC (Marine and Environmental
Technology Research Center) at
Instituto Superior Técnico
(IST) which belongs to Technical University of Lisbon.
The MOHID modelling system allows
the adoption of an integrated modelling philosophy,
not only of processes (physical and biogeochemical), but also of
different scales (allowing the use of nested models) and systems
(estuaries and watersheds), due to the adoption of an object
oriented programming philosophy.
The integration of MOHID different
tools, (MOHID Water, MOHID Land and MOHID Soil) can be used to
study the water cycle in an integrated approach. Since these tools are
based on the same framework, the coupling of them is easily achieved.
The integrated Trancao Basin / Tagus Estuary System
MOHID has been applied
to different study cases, as coastal and estuarine areas, as well as
oceanic processes and reservoirs, and it has showed its ability to
simulate complex features of the flows.
Main Properties
 |
possibility to run different
applications simultaneously
|
|
easily adaptable to new
application areas
|
|
can use different time steps for
different modules
|
|
permits to use the model in any
dimension (1D, 2D and 3D)
|
|
spatial discretization using the
finite volume approach technique (the spatial coordinates are
independent, and any geometry can be chosen for every dimension),
allowing more flexibility in the subdivision of the vertical and
horizontal domain, and in implementation of innovative vertical
coordinates, adaptable to each particular case.
|
|
can use nested models, only
limited by the available computacional power
|
|
Possibility of parallel running of different models in separated
processors, communicating between themselves using the MPI protocol
(Message Passing Interface), thus allowing a very meaningful gain in
calculating time |
