Kühlquellen
Kühlquellen, also known as cold springs, are natural springs that discharge groundwater at a significantly lower temperature than the ambient air temperature. These springs are typically found in regions with geological features that allow for the circulation of groundwater deep within the Earth's crust. The cool temperatures are a result of the groundwater's prolonged contact with cooler subterranean rock layers.
The flow of Kühlquellen can vary greatly, from a gentle seep to a robust stream. The water
Geologically, Kühlquellen are often associated with karst topography, fractured bedrock, or areas with significant geothermal gradients.
