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:



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



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.
