This standard is applicable to winter flood calculations in the feasibility study and preliminary design stages of large and medium-sized water conservancy and hydropower projects. The calculation of peak floods in the proposal stage of large and medium-sized water conservancy and hydropower projects, small water conservancy and hydropower projects, other cross-river projects and river basin planning can be implemented as a reference.
