Waterworks, pumping stations, hydroelectric dams, and the like typically require relatively accurate measurements of the depth of the impounded water. The conventional measurement method is to mark scales on the dam from bottom to top and measure the depth of stored water according to the scale value on the horizontal plane indication dam. However, when silt or silt is accumulated at the bottom of the stored water, the zero scale line at the bottom of the water is buried under the accumulated silt or silt, so that the method for measuring the depth of the stored water by the scale value on the dam is not accurate enough. Another method is to use a flexible rope measurement method, i.e. binding an iron block on the lower part of the flexible rope, then slowly sinking the iron block and the flexible rope vertically downwards to the water bottom until the iron block touches the sediment on the water bottom. During this period, the flexible cord is kept in tension and a mark is made at the interface of the cord and the horizontal plane. And then pulling the flexible rope out of the water surface, and measuring the length from the bottom of the iron block to the mark of the rope, thereby measuring the water depth.
