Pressurized water lake
A pressurized water lake or spring basin lake is a body of water that is created by rising - pushing up - groundwater , with depressions or lower-lying parts of the terrain being filled with exposed water . So even if they have a drain they have no discernible inflow.
Pressurized water lakes can be divided into several types:
- Spring lakes in the real sense, these are springs that pour so heavily that they keep the lake level constant ( spring pots , lakes at the foot of mountains and slopes without a superficial inlet, and other forms)
- Temporary bodies of water due to an excessive rise in the groundwater level, e.g. during floods
- Waters through pressurized water from the dyke construction , i.e. secondary phenomena of the technical change in the groundwater conditions
- Artesian spring lakes are bodies of water that form in depressions due to locally tensed groundwater levels far away from a source area in the true sense
- Hydrothermal lakes , in which the water is pushed up by heating in the depths (e.g. lakes around geysers )
Pressurized water lakes form one of the basic classes of geomorphological typing of still waters, i.e. according to the hydrographic context of the lake basin.
No pressure water lakes are groundwater lakes , where the water accumulates only by the deepening of the surface, so the water table is cut and is exposed (about lakes), or pools , which arise because the amounts of water can no longer seep into the ground during heavy rainfalls parts and collect in sinks (water accumulation due to soil saturation, not water pressure).
Most lakes in mountain areas have a certain proportion of pressurized water supply; in the case of transitional forms, the character can only be determined by more precise measurement of the inflow and outflow (which is time-consuming because the water remains in the still water, which is usually unknown), or can at least be proven in principle by means of marking experiments . Still waters of course almost always represent the - or at least one - groundwater horizon in general, which is not taken into account as a special form in the distinction between pressurized and groundwater lakes.
