strömningsriktningen
Strömningsriktningen refers to the direction in which a fluid (e.g., water, air, or electricity) moves. In geography and hydrology, it describes surface runoff, groundwater flow, or river currents, often visualized with flow lines/arrows on maps to show how water travels across terrain, influenced by topography, land cover, and precipitation. In engineering, it is critical for designing efficient systems like drainage networks or ventilation ducts. Accurate determination supports resource management, flood prediction, and environmental assessment by revealing patterns in water movement and energy transfer.
