The water table does fluctuate, primarily due to seasonal changes, precipitation patterns, and various other environmental factors. During wet seasons or periods of significant rainfall, the water table typically rises as more water infiltrates the ground. Conversely, during dry seasons or drought conditions, the water table can fall as water is drawn from the soil and groundwater reserves for various uses, including irrigation and consumption.

While some might think that fluctuations are only observed during heavy rains, this is not accurate, as the water table will experience more gradual and regular changes based on seasonal shifts. The idea that fluctuations occur only in arid regions overlooks the dynamics present in humid or temperate areas where the water table is also responsive to seasonal changes and human activities affecting water usage and recharge rates. Understanding these fluctuations is crucial for construction and land development, as it impacts soil stability and drainage considerations.
