Vízáramlások refers to the movement of water within a body of water, such as a river, lake, ocean, or groundwater. This movement can be driven by various forces including gravity, wind, temperature differences, and salinity gradients. Understanding water flow is crucial in many scientific and engineering disciplines.

In rivers, water flow is primarily driven by gravity, causing water to move from higher elevations to lower ones. The speed and volume of river flow are influenced by factors like the riverbed's slope, the amount of rainfall or snowmelt, and the presence of obstacles. Ocean currents are vast, continuous movements of seawater that play a significant role in global climate regulation and nutrient distribution. These currents are influenced by wind patterns, the Earth's rotation (Coriolis effect), and differences in water density.

Lakes also exhibit water movement, though typically on a smaller scale than oceans or large rivers. Wind can create surface currents and waves, while temperature and density variations can lead to internal circulation. Groundwater flow describes the movement of water beneath the Earth's surface through porous rock and soil. This flow is typically slow and driven by pressure gradients within the aquifer.

The study of water flow, known as fluid dynamics or hydrology, is essential for managing water resources, designing infrastructure like dams and canals, predicting weather patterns, and understanding ecological processes. Analyzing water flow patterns helps in assessing flood risks, optimizing irrigation, and studying marine ecosystems.
