Advection diffusion sedimentation in volcano simulations

The people leading their lives near active volcanoes are under the grave threat due to the fallout of the volcanic ash. It can disrupt the air-traffic, harm the agro-based activities, destroys the residential structures due to overloading, et cetera. It is essential to understand the evolution of the fallout of the volcanic ash using attested computational methods. Eulerian models are used to simulate the deposit and transport of the volcanic ashes. Such a model uses advection-diffusion-sedimentation equation along with turbulent diffusion. Using this, allows to forecast ash loading on a surface and the ash concentration in the atmosphere.
