This standard specifies the basic principles, work content and technical requirements that should be followed for hydrological calculations of hydropower and water conservancy projects. This standard is applicable to hydrological calculations in the pre-feasibility study and feasibility study stages of large and medium-sized hydropower and water conservancy projects (including pumped storage power stations). River hydropower planning, bidding and construction detailed drawing design stages of large and medium-sized hydropower and water conservancy projects (including pumped storage power stations), and hydrological calculations of small hydropower and water conservancy projects can be implemented as a reference.
