Historical synthesis of the International Commission on Water Resources Systems.

The planning, designing, management, and operation of water systems has been one of the most important activities throughout the history of humankind. However, as a scientific and applied discipline, it evolved about 70 years ago. The International Commission on Water Resources Systems (ICWRS) has primarily focused on developing and implementing improved methods for water resources management for the benefit of society since the 1970s. This paper reviews the history of the water resources systems (WRS) discipline over these six decades after the 100th anniversary of the International Association of Hydrological Sciences (IAHS) and aims to make a synthesis of the history of ICWRS. In the concluding section, an outlook for researchers and decision makers on the future development of WRS research is also provided. [ABSTRACT FROM AUTHOR]
