IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Incompressible finite pointset method for free surface flow
Author : R. Vacondio and P. Mignosa
In this paper a Finite PointSet Method for the numerical simulation of viscous incompressible flow in presence of free surface is presented. Finite Pointset Method is a pure Lagrangian method based on Moving Least Square interpolations and uses a Projection Method to reproduce the incompressibility. In this paper a modified form of Chorinís original method is presented: the main advantage of this new formulation is the capability to reproduce the hydrostatic condition for free surface flow. A new technique for free surface detection based on the the geometrical characteristics of particle positions is proposed and tested: this solves problems of free surface detection of methods used in Incompressible SPH. In order to stabilize the numerical model a variable smoothing length and an algorithm to insert and remove particles is applied.
