Anthropic and Natural Fluid Flows is the collective name of a group of researchers of CERIS-IST, LNEC and FCT-UNova. AniFlow's aims are i) to carry out fundamental and applied research in all aspects of fluid mechanics relevant to characterize processes observed in the natural and built environments and ii) to develop consultancy in areas requiring a deep knowledge of fluid mechanics. Recent activity has been focused in experimental research in fluvial processes, development of laboratory instrumentation and mathematical modeling of open-channel flows.
