A aquifer.is a locally limited area where groundwater discharges at the surface from an underground
Springs are generally small features located in a rural or mountainous environment, but may have major importance as the headwaters of streams and rivers.
Some springs are impressive due to their high discharge, like the fontaine du Vaucluse. Especially in dry areas, springs are traditionally prominently marked on topographic maps.
Hot springs have temperatures significantly higher than the average air temperature of the surrounding region. A proposal for hot springs is under way also covering water characteristics.
How to Map
Tags to use in combination
- drinking_water=yes/no Indication whether a feature provides drinking water.
- drinking_water:legal=yes/no the water is checked and approved by public authorities
A spring can be part of a karst system: its water may come from ponors or estavelles, and from several of them. If so, tag the spring also with karst=yes; that would model the spring as karstic, meaning that it throughput and the quality of its water may greatly vary. You may also want to map the relation between it and the other members of the karst system; if so, please read sinkhole=* to know how.
Use water_characteristic=* to specify mineral, gas or other content if notable. This could be multivalued, but usually there is a main name giving characteristic which should the first value. See Proposed features/Hot Spring for details. Main values (please amend):
- mineral - mineral salts
- mineral, hot water, salty spring
- intermittent or perennial
- artesian well
- natural=cave_entrance Some spring, especially resurgence are also caves.
- natural=volcano Hot springs may be associated with volcanic features.
- Proposed features/Volcanic features.
- amenity=drinking_water Place to get "drinking water" in smaller amounts for personal usage (hiking, spa, ...).
- amenity=water_point Place to get larger amounts of "drinking water" e.g. for caravans.
- amenity=fountain A fountain for cultural / decorational / recreational purposes.
- man_made=water_well A man made excavation in the ground to gain water from an aquifer.
- sinkhole=* A spring may be part of a karst system, made of several sinkholes and spring interconnected by underground water flows.
