MOHID Water
MOHID Water is a three-dimensional numerical program
to simulate surface water bodies (oceans, estuaries, reservoirs).

MOHID Water
scheme: main classes involved
MOHID model has been applied to
several coastal and estuarine areas and it has showed its ability to
simulate complex features of the flows. Along the Portuguese coast,
different environments have been studied, including the main estuaries (Minho,
Lima, Douro, Mondego, Tejo, Sado, Mira, Arade and Guadiana) and coastal
lagoons (Ria de Aveiro and Ria Formosa).
The model has been
also implemented in most Galician Rķas: Rķa de Vigo , Rķa de Pontevedra.
Far from the Atlantic coast of the Iberian Peninsula, some European
estuaries have been modelled - Western Scheldt , The Netherlands,
Gironde, France, and Carlingford, Ireland - as well as some
estuaries in Brasil. Regarding to open sea, MOHID has been applied to
the North-East Atlantic region where some processes including the
Portuguese coastal current, the slope current along the European
Atlantic shelf break, and the generation of internal tides, and also to
the Mediterranean Sea to simulate the seasonal cycle, or the circulation
in the Alboran Sea. More recently MOHID has been applied to the several
Portuguese fresh water reservoirs Monte Novo, Roxo and Alqueva, in order
to study flow and water quality.
Main scientific areas covered by
MOHID Water are:
|
Hydrodynamics |
Circulation patterns and velocity
fields that transports the model available water properties
(sediments, phytoplankton, nitrate, arsenic, ammonia ...) |
|
Waves |
wave difraction and refraction
and its influence on sediment transport |
|
Sediments Transport |
Sediments - vertical and horizontal
movement and bottom physical processes |
|
Sands |
|
| Water Quality & Ecology |
Primary and secondary production and nutrient
cycle (nitrogen and phosforous). |
|
Plume Dispersion |
Jet Model |
Simulates the initial dilution and trajectory of
fluids associated to outfall jets (near field). |
|
Lagrangian
Transport Model |
Simulates the dispersion and trajectory of fluids
in the far field. |
|
Jet Model |
Simulates the trajectory and dilution of fluids
associated to outfall jets. |
| Oil Spills |
Prediction and simulation of the trajectory and
weathering processes involved in spilled oil, assuming that oil
can be idealized as a large number of particles that
independently move in water. |
|
Turbulence |
Determines turbulent transport of momentum, mass and heat. |
