Finite elements, water quality modelling, adsorptive pollutants, sediment transport


The close interaction between humans, animals and the river system requires to have control about the concentration of different pollutants in the water column in order to avoid damage to the environment. Due to the fact that the measurements are time consuming, expensive and in most of the cases very local, it is required to develop tools in order to predict the spatial and temporal distribution of the pollutants in the system.

Once pollutant effluents are discharged in waters, part of them is transported in liquid phase and the rest is attached to the suspended sediments and to the bed sediments. The magnitude of each fraction is determined classically by the partition coefficient Kd that is a function of several environmental parameters such as the pH.
