Groundwater detection refers to the methods used to locate and assess underground water sources. This process is essential for water resource management, agriculture, and environmental protection. Techniques include geological surveys, electrical resistivity, and remote sensing, which help identify aquifers and their characteristics. The importance of groundwater detection lies in its role in sustainable water use. By accurately locating groundwater, communities can ensure a reliable water supply for drinking, irrigation, and industrial purposes. Additionally, understanding groundwater levels can aid in preventing issues like land subsidence and contamination from pollutants.
