Enhancement of water resources management utilizing global me-teoro-hydrological information

点击翻译按钮获取中文摘要

A decision support technique for long-term reservoir operation was developed by use of global meteoro-hydrological information, which has been recently well developed worldwide. Deterministic and stochastic prediction methods of basin precipita-tion and streamflow for the coming three months were developed by utilizing global dis-tributional characteristics of pressure height, temperature and sea surface temperature. Decision support methods for long-term water release of a reservoir with consideration of the predictions were also developed, and then introduced to a real-time decision support system for reservoir operation.
