Discovering underground water sources is a critical task, and relying on scientifically validated geophysical methods is recommended for accurate and reliable results. Using objects like coconuts or divining rods, associated with superstitious practices, lack scientific evidence and are not considered reliable. Instead, methods like electrical resistivity surveys, ground-penetrating radar, or seismic methods are used to assess the presence and characteristics of water-bearing formations. Traditional methods like divining or dowsing, observation of surface features, and gathering historical information can provide insights but are not scientifically reliable.
