Talajvízszintek, or groundwater levels, refer to the depth at which water is found in the soil or rock below the Earth's surface. These levels are crucial for understanding water availability and movement within the subsurface. Groundwater is stored in the pores and fractures of geological formations, and its level can vary significantly over time and space.

Groundwater levels are influenced by several factors, including precipitation, evaporation, plant transpiration, and human activities such as pumping from wells. In aquifers, which are permeable geological formations that can store and transmit groundwater, the water table is the boundary between the saturated zone, where all pores are filled with water, and the unsaturated zone, where some pores are filled with air.

Monitoring groundwater levels is essential for managing water resources, predicting floods, and assessing the impact of climate change. Techniques such as piezometers, which are wells installed in aquifers, are used to measure groundwater levels. These measurements are often recorded over time to create hydrographs, which show the fluctuations in groundwater levels.

Groundwater levels can be affected by both natural and anthropogenic factors. Natural factors include seasonal variations in precipitation and recharge rates, while anthropogenic factors include groundwater extraction for irrigation, drinking water supply, and industrial use. Sustainable management of groundwater resources requires a comprehensive understanding of groundwater levels and their dynamics.
