Various environmental engineering applications related to water resources involve unsteady free surface flows. A full 3D models based on Navier-Stokes equations are a good description of the physical features concerning several phenomena as for example lake eutrophication, transport of pollutant, flood in rivers, watershed, etc. However these models are characterized by an important computational effort, that we aim to reduce in some case by the help of 2D models or by appropriate coupling models of different dimensions and by the use of the parallel algorithmic trough HPCN facilities. In this work, we present an overview of some approximations methodologies and techniques for an efficient numerical modelling of water free surface problems in a finite element context.
