Revision Notes
In April 1993, the State Planning Commission issued the task of revising the national standard "Standards for Basic Hydrological Terms and Symbols" in Document No. [1993]110. Our department established a compilation team in Beijing in August of the same year, and the standard has been compiled and reviewed and approved. The main contents of the standard include terms and symbols in the fields of hydrological surveys, information forecasts, analysis and calculations, water resources, water environment, etc. in the terrestrial hydrology discipline.
During the preparation of this standard, the current hydrological and related professional terminology and symbol specifications (standards) in my country were referred to, and attention was paid to international standards. The international standards for hydrological terms and symbols were used for reference. On this basis, the standard text was formed after repeated consultation and revision. This standard is a comprehensive expansion and development of the national standard GBJ95-86 "Hydrological Survey Terms and Symbols Standards" implemented on July 1, 1987. In the process of using this standard, it is hoped that all units will summarize experience and accumulate information in a timely manner. If any modification or supplement is found, please send your opinions and relevant information to the National Standard "Hydrological Basic Terms and Symbols Standards" Management Group of Nanjing Hydrology and Water Resources Research Institute of the Ministry of Water Resources (Address: No. 1, Xikang Road, Nanjing, Jiangsu Province, Postal Code: 210024).
