Hydrological simulation and prediction for environmental change
نویسندگان
چکیده
A strong environmental change has been recognized in China with the impacts of climate change and intensive human activities on land use. In this paper, first environmental changes in China, such as those caused by human activities, land use, climate change, and social and economic development, are presented. Secondly, the hydrological prediction models and systems and their application in China are briefly introduced. Finally, it is pointed out that new hydrological prediction models, such as distributed hydrological models based on geographical information, should be developed because long-time data series will be invalid for traditional model calibration due to changing current and future environmental conditions.
