Models of pollutant transport in natural aquifers

Finite Volume/Mixed Finite Element Analysis of Pollutant Transport and Bioremediation in Heterogeneous Saturated Aquifers

Numerical Simulation of Pollutant Transport in Fractured Vuggy Porous Karstic Aquifers

This paper begins with presenting a mathematical model for contaminant transport in the fractured vuggy porous media of a species of contaminant PCP . Two phases are numerically simulated for a process of contaminant and clean water infiltrated in the fractured vuggy porous media by coupling mixed finite element MFE method and finite volume method FVM , both of which are locally conservative, t...

Analytical models of contaminant transport in coastal aquifers

The Henry formulation, which couples subsurface flow and salt transport via a variable-density flow formulation, can be used to evaluate the extent of sea water intrusion into coastal aquifers. The coupling gives rise to nontrivial flow patterns that are very different from those observed in inland aquifers. We investigate the influence of these flow patterns on the transport of conservative co...

one-dimensional pollutant transport model in natural rivers, with emphasis on the role of storage zones

rivers are one of the major resources of drinking and agriculture water, so accurate control and modeling of their water quality is essential for protection of human health and environment stability. transient storage zones have a great effect on contaminant transport, especially in small mountain streams. the main effects include temporary detainment of solute and decrease its concentration in...

Hydrodynamic and pollutant transport models applied to coastal seas

Role of mathematical models and of field measurements in solving water quality problems is described. When simulating phenomena in different space and time scales there are some important differences, regarding forcing factors, time averaging and measuring technique. Two case studies are presented: (a) Modelling of mercury cycling in Trieste Bay. 2D Hydrodynamic model Is used together with a se...
