At present the problematic of floods is larger than ever because global warming, deforestation and other factors increase chance of flood creation. As prevention to floods, designing of many new anti-floods projects have been started. In the future, these projects will stop floods completely or at least reduce their consequences. Water flow simulation and visualization is an integral part of this process. Simulation is used for testing, if the project meets flood protection requirements. Visualization is used for presenting and helps investors and wide public to better understand these projects. Stereoscopic visualization can be also used, because displaying of outputs from simulation and visualization is important, too. This paper aims at fluid flow simulation and visualization software. Also aims at hardware that can be used for stereoscopic visualization.
