[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. The water level and its changes over a long period of time are important parameters for studying groundwater seepage, dam seepage safety, pipe flow and flood control. Therefore, accurate measurement and monitoring of water levels are of great theoretical and practical significance.
