Form
The water table may vary due to seasonal changes in precipitation, evapotranspiration, topography and structural geology. In undeveloped regions with permeable soils that receive sufficient amounts of precipitation, the water table typically slopes toward rivers that act to drain the groundwater away and release the pressure in the aquifer. Springs, rivers, lakes and oases occur when the water table reaches the surface. Springs commonly form on hillsides, where the Earth's slanting surface may "intersect" with the water table. Groundwater entering rivers and lakes accounts for the base-flow water levels in water bodies.
