Groundwater is an indispensable and important water resource for human life and industrial activities, and accurate detection and assessment of groundwater sources is crucial. To address some of the limitations of traditional water source detection methods, this paper proposes a ground water detector based on the principle of natural electric field. by utilizing the natural electric field generated by the difference in electrical conductivity between the groundwater layer and the rock or soil, the detector is able to acquire real-time information about the groundwater and provide high-precision data on the location of the water source and the water content.

As urbanization accelerates and water supplies become tighter, the management and protection of groundwater is becoming increasingly important. However, traditional methods of groundwater detection suffer from the problems of expensive, time-consuming and intrusive instruments. Therefore, it is of great research value to find a convenient, efficient and economical ground water source detection method.


The ground water detector proposed in this paper utilizes the principle of natural electric field to obtain real-time groundwater information without disturbing the groundwater layer. When the electrical conductivity of the groundwater layer is different from that of the surrounding rock or soil, a weak but measurable electric field is formed. By deploying multiple receiving electrodes and one transmitting electrode, we are able to infer the location and water content of the groundwater source by measuring the potential difference in the underground waters.


We conducted several sets of experiments in actual underground waters to verify the effectiveness of the ground water detector. The comparison between the electric field changes calculated from the measured data and the geographic location of the ground water source shows that the proposed detector is able to accurately determine the location of the ground water source and has a high measurement accuracy. In addition, experiments on groundwater layers with different water contents have been conducted, and the results also confirm the ability of the detector to accurately measure the water content of groundwater.


The ground water detector based on the principle of natural electric field has the advantages of convenience, high efficiency, and economy, which will provide important support for the management and protection of groundwater resources. The detector can be widely used in the fields of urban water supply planning, farmland irrigation, and groundwater environmental monitoring. In the future, we can further improve the technology of the detector to increase the detection accuracy and explore its potential in more application scenarios.


The ground water detector based on the principle of natural electric field proposed in this study realizes the accurate measurement of groundwater source location and water content by exploiting the difference in electrical conductivity between the groundwater layer and the surrounding rock or soil. With the advantages of convenience, efficiency and economy, the detector is expected to provide important support for the management and protection of groundwater resources, and to be widely used in the fields of urban water supply planning and farmland irrigation.
