The objective of this research project is to develop the techniques and models for hydrological prediction in un-gauged or poorly gauged river basins. The following working groups are established in Japan PUB.1. Estimating frequencies of hydrologic extreme events in ungauged basins by using scaling, regionalization, and historical record analysis.2. Establishment of a guide line for selecting hydrologic models through a development of uncertainty evaluation indices.3. Relating hydrologic diversity to landscape elements to establish a realistic PUB model.4. Global-scale hydrological modeling considering interaction between natural variation and anthropogenic activities.5. Downscaling of global hydrologic information for local scale watershed managements in ungauged basins.

本研究的目的是发展无资料或资料贫乏的河川流域的水文预测技术和模式。在日本设立了以下工作组PUB.1。利用尺度、区域化和历史资料分析估算无资料流域极端水文事件发生频率.通过建立水文模型不确定性评价指标，建立水文模型选择的指导原则.将水文多样性与景观要素联系起来，建立符合实际的PUB模型.考虑自然变化和人类活动相互作用的全球尺度水文模拟.无资料流域局部尺度流域管理的全球水文信息降尺度。
