Groundwater flow refers to the movement of water through the soil and rock layers beneath the Earth's surface. This water, known as groundwater, is stored in underground reservoirs called aquifers. The flow is influenced by factors such as soil permeability, the slope of the land, and the amount of precipitation. As groundwater moves, it can travel slowly through porous materials, sometimes taking years to reach a discharge point like a river or lake. Understanding groundwater flow is essential for managing water resources, preventing contamination, and ensuring sustainable use of aquifers for drinking water and irrigation.
