Groundwater modeling is a scientific method used to simulate and analyze the movement and distribution of water beneath the Earth's surface. It helps researchers understand how groundwater interacts with various factors, such as soil types, geological formations, and human activities. By creating computer models, scientists can predict how changes in land use or climate may affect groundwater resources. These models are essential for managing water supplies, assessing contamination risks, and planning for sustainable use. Groundwater modeling can also aid in the design of water wells and irrigation systems, ensuring that water is used efficiently and responsibly in agriculture and urban development.
