Visualization of flow simulation data in environmental modeling

This paper introduces a flow visualization system and an application environmental modeling. A collection of 2D and 3D flow visualization methods suitable for flow simulation data are discussed. Emphasis is laid on techniques related to the simulation of the propagation of massless particles in the flow, like particle tracing and particle pathways. The scientific visualization system apE together with a set of enhancements for flow visualization forms a gereric flow visualization system. The resulting system is used for evaluating simulation data provided by numerical models of water flows.
