Groundwater flow refers to the movement of water through the soil and rock layers beneath the Earth's surface, driven primarily by gravity and pressure gradients. This process is a vital component of the hydrologic cycle, as it plays a significant role in replenishing surface water bodies, sustaining ecosystems, and influencing water availability for human use. Understanding groundwater flow helps us grasp how water interacts with the land, how aquifers function, and how it ultimately connects to surface water systems.
