Wind and freshwater influence over hydrocarbon dispersal on Patos Lagoon, Brazil

Evaluation of hydrologic influence on water quality variation in a coastal lagoon through numerical modeling

“…Its temporal discretization is based on the semi-implicit scheme and the spatial discretization on the finite volume approach, which ensures the conservation of mass of the simulated properties (Marshall et al, 1997) and flexibility on grid definition (Janeiro et al, 2008). The model is divided into modules, each of which manages one type of information.…”

“…The model is divided into modules, each of which manages one type of information. For the study, some fundamental modules were used, such as the hydrodynamic module, which calculates the flow properties as the water elevation and velocity fields (Vaz et al, 2007;Janeiro et al, 2008;Deus et al, 2013); water properties module, responsible for managing the evolution of variables, including their transport through streams, river discharge, sedimentation and the interaction with the bottom and with the surface (involving exchanges of heat and oxygen), and the water quality module, responsible for simulation of biogeochemical processes and the spatial and temporal variability of water quality variables in the water column (Deus et al, 2013).…”

“…The values were based on Janeiro et al (2008). The model capability was tested by comparing measurements of water level from ANA with model calculated values at points Ponta Grossa, Laranjal and Rio Grande (Fig.…”

Integrating technologies for oil spill response in the SW Iberian coast

“…To simulate the oil spill trajectories and weathering processes, the multi-mesh Lagrangean model (Fernandes et al 2013) implemented in MOHID is used together with its oil weathering model (Janeiro et al 2008). Here, the spatial evolution of the particles is computed integrating the definition of velocity:…”

“…MOHID oil module (Fernandes 2001;Janeiro et al 2008) include the physical processes of the oil (density and viscosity) and the weathering processes (e.g. evaporation, dispersion, emulsification, dissolution), updating the module in each timestep.…”
