Description

technical field [0001] The invention relates to a device and a method for measuring the resistivity of water bodies, in particular to a device and a method for measuring the resistivity of underwater water bodies at different depths, and belongs to the field of geophysical exploration. Background technique [0002] From the use of water, there may be drinking water, agricultural water, industrial water, etc. Due to different uses, the requirements for water quality are also different. Water quality analysis plays a very important role in the national economy. The temperature and turbidity of water in large and medium-sized reservoirs and deep rivers are generally distributed in layers, so it is necessary to investigate and study water in different layers of reservoirs and rivers. Since water quality is related to water resistivity, measuring the resistivity of different water layers is one of the indispensable and important tasks in the field of water resource investigation....
