feljebbáramlását

Feljebbáramlását is a Hungarian term that translates directly to "upward flow" or "upward current." In a geographical and hydrological context, it refers to the movement of water against gravity, typically driven by geological forces or specific environmental conditions. This phenomenon is distinct from standard surface runoff or gravity-driven flow.

One notable context where feljebbáramlását is observed is in certain karst landscapes. Here, underground water sources under hydrostatic pressure can force water upwards through fissures and conduits in the rock, sometimes emerging at higher elevations than their apparent source. This can create unique spring formations and influence groundwater dynamics.

Another instance can be related to geothermal activity. In areas with volcanic or geothermal energy, heated groundwater can rise towards the surface, creating hot springs, geysers, or areas of increased soil temperature. This upward movement is a direct result of thermal expansion and pressure differences within the Earth's crust.

While the term is not widely used in English hydrological literature, the concept it describes is recognized and studied under various related phenomena such as artesian springs, upward seepage, or geothermal upwelling. Understanding feljebbáramlását is crucial for comprehending complex groundwater systems and geological processes in specific regions.
