Global hydrological modeling to analyze the effects of climate, land use & socioeconomic change on the world's water resources

气候和全球变化最严重的后果之一是改变水资源的时空分布。需要采取缓解和适应战略，使社会和环境做好准备，以应对可能出现的供水减少、河流流量越来越不稳定或洪水和干旱等更频繁的极端事件。这些战略，反过来，需要的情景和建模方法已成为关键的科学工具，以估计未来的水文条件。

Among the most critical consequences of climate and global change are alterations in the spatial and temporal distribution of water resources. Mitigation and adaptation strategies are needed to prepare both society and the environment for potentially diminishing water supplies, increasingly erratic river flows, or more frequent extreme events such as floods and droughts. These strategies, in turn, require scenarios and modeling approaches which have emerged as key scientific tools to estimate future hydrologic conditions.
