How does the water table depth change?

The water table depth fluctuates throughout the year due to various factors, including precipitation, evaporation, and changes in water use by plants and humans. During wet periods, such as after heavy rainfall or snowmelt, the water table rises as more water infiltrates the soil. Conversely, during dry periods or droughts, the water table can drop due to increased evaporation rates and lower water input from precipitation. Additionally, groundwater extraction for agricultural and urban needs can further influence the water table's depth, contributing to its year-round fluctuations.

Understanding these dynamics is crucial, as they affect crop growth, soil health, and pest management strategies. Effective pest management practices often rely on knowing the local hydrology, as changes in the water table can also impact pest populations and the effectiveness of various management techniques.
