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

bullet

possibility to run different applications simultaneously

bullet

easily adaptable to new application areas

bullet

can use different time steps for different modules

bullet

permits to use the model in any dimension (1D, 2D and 3D)

bullet

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.

bullet

can use nested models, only limited by the available computacional power

bullet

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
