Simulation of contaminant transport due to rain runoffs by a Lagrangian particle method

A mesh-free Lagrangian particle method of modelling the overland flow due to rainfalls is applied to track runoff water to examine the transports and the fate of contaminants in flat urban-agriculture mixed land use area. In contrast to most existing methods that are based on two-dimensional fixed Eulerian grids, the L...
