[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. Water samples from rivers are collected and analyzed to obtain basic data on the composition of the water body. The water samples used for analysis should be representative and reflect the chemical composition and characteristics of the water body. The sampling method, depth, location, etc. are all determined according to the characteristics of the water body and the purpose of analysis.
