voolusuunast
Voolusuunast is a term used in fluid dynamics and earth sciences to denote the dominant direction of fluid flow at a given location and moment. In practice, it refers to the principal orientation of the velocity vector, describing where the water or air is moving toward on average over a defined time interval. The concept is used in oceanography, river hydrology, meteorology and coastal engineering to summarize complex flow patterns for navigation, modeling or environmental assessment.
In Estonian usage, voolusuunast is often considered together with flow speed, yielding a flow vector defined
Measurement and calculation of voolusuunast rely on data from instruments such as Acoustic Doppler Current Profilers
Applications include navigation safety, pollutant dispersion modeling, harbor design, flood risk assessment and ecosystem studies. The
