Dispersão do metano na baixa atmosfera do Pantanal mato-grossense

Abstract

Despite the wide literature on the Pantanal, there are no studies of the problem of methane dispersion by mathematical models and computational simulations. This work proposes a model based on a general equation of transport, a di usion-advection equation, with the objective of simulating scenarios of the dispersion of methane near the water surface in the region of Chacorore Bay, in the Pantanal of Matogrosso. The solution is given by numerical approximation using the nite element method (FEM) for spatial approximations and the Crank-Nicolson method for temporal approximations. In the domain we use a non structured mesh. Finally, a numerical code for computational simulations is presented, as well as some numerical results used to produce qualitatively suitable graphical outputs to evaluate possible scenarios of impact.
