The purpose of this study is to develop the method for "down scaling" from global-scale observations into local-scale hydrological information. This study is a part of Japan PUB (Prediction in Ungauged basins) group activity, and consists of following four main topics:-Stochastic hydrological model for prediction in ungauged basins.-Transferability of distributed hydrological model based on topographic similarity.-Near-real time forecasting of river flow using output of meso-scale atmospheric model-Global hydro-meteorological model considering the anthropogenic effect on water cycle-Design of new blind-test methodology for ungauged basins in Asian regionThe developed models/methods mentioned above are applied to the Irrawaddy river basin (Myanmar) to evaluate how these models can improve hydrological predictability in ungauged basins, and to show the uncertainty level on prediction in ungauged basins. Finally, "Myanmar-Japan Bilateral Workshop on "Predictions of Ungauged Basins (PUB) for Improved River Basin Management" (organized by Japan PUB research group, Water Training Center, and Irrigation Department of Myanmar) was held, and the result of application in Irrawaddy basin was reported. Through this workshop, future perspectives of prediction in ungauged basins, use of hydrological model for integrated river basin management in developing countries were discussed.

本研究的目的是开发从全球尺度观测“缩小”到局部尺度水文信息的方法。本研究是日本 PUB（未测量流域预测）小组活动的一部分，由以下四个主要主题组成：-未测量流域预测的随机水文模型。-基于地形相似性的分布式水文模型的可移植性。-近真实利用中尺度大气模型输出的河流流量时间预测-考虑人为对水循环影响的全球水文气象模型-新的非计量盲测方法设计亚洲地区流域上述开发的模型/方法应用于伊洛瓦底江流域（缅甸），以评估这些模型如何提高未计量流域的水文可预测性，并显示未计量流域预测的不确定性水平。最后，举办了“缅甸-日本双边研讨会“预测未测量流域（PUB）以改善流域管理”（由日本PUB研究小组、水培训中心和缅甸灌溉部门主办），并将应用结果通过这次研讨会，报告了伊洛瓦底江流域的未来前景，讨论了发展中国家流域综合管理中水文模型的应用。
