Strömunngsquellen

Strömungsquellen are locations from which a fluid current originates and is discharged. In German-language geoscience literature the term is used primarily for natural discharge points of groundwater, but it also appears in oceanographic contexts to describe sources of upwelling or venting seawater. The standard spelling is Strömungsquellen; Strömunngsquellen is a less common variant found in older texts.

A Strömungsquelle forms where hydraulic pressure in a subsurface reservoir drives water to the surface or into a conduit. In karst and fractured rock settings, groundwater can emerge as springs; in geothermal regions, hot springs are a subset. In marine environments, submarine vents and hydrothermal plumes act as sources for fluid discharge that can influence local currents and chemistry.

Characteristics used to classify Strömungsquellen include temperature (cold, warm, hot), mineral content (fresh versus mineral-rich), and discharge rate (constant, seasonal, ephemeral). They are important for water supply, ecological habitats, geochemical cycles, and landscape development, and they can indicate the structure and connectivity of an aquifer or fault zones.

Methods to study them include discharge measurements, temperature and chemical profiling, tracer tests to track flow paths, and isotopic analyses. Mapping Strömungsquellen aids understanding of groundwater recharge, resource management, and hazard assessment such as contamination pathways or subsidence.
