JAPAN PUB NATIONAL WORKSHOP,JAPAN PUB NATIONAL WORKSHOP,Nov. 3-5, 2004Nov. 3-5, 2004
Two projects to link PUB Two projects to link PUB WGsWGs
1. How hydrologic model could/can predict the floods hit Japan in 2004?
When we choose and identify a flood runoff model, we usually do not have severe flood data (1/100 flood etc.).
2. How hydrologic models work at ungauged basins? Blind Test
Blind test of hydrologic models at(1) Maecham River basin in Thailand.(2) Saloween River basin in Burma.
Give forcing data created from global scale data set.
Design of blind test is important. (1) What conditions we suppose? Suppose completely no data? Or . . . ?(2) How the results of blind test utilize to improve models and understanding?

PUB (Prediction in Ungauged Basins) Session on Methodology of Trans-Regional
Application of Hydrological Models
International Conference on Sustainable Water Resources Management in Changing Environment of the Monsoon
(WRMinCE)Colombo, Sri Lanka, November 17, 2004
- 12 Presentation Related to Methodology of Trans-Regional application of Hydrological Models
- General Discussion (Working Group in the Region)
Conclusions from PUB related Discussion with Special Focus to
South Asia
Hydrological Prediction is an urgent need in the South Asia.Hydrological data in the region is very limited, poorly gauged and quality is low.Participants showed great interest in PUB and are interested in forming WG in the region for PUB research.The delegates from Nepal, India, Bangladesh, and Uganda will discuss forming PUB WGs in their countries.
Thai PUB WG has been newly formed.Sri Lanka PUB WG will be formed very near future. Nepalese PUB WG has been newly formed.

PUB/LSM at Kyoto, Jan. 20-22, 2005
Session 1 : Land surface models (LSMs) on a global scale and hydrological watershed models (HWMs) for macro-scale applications.Session 2 : Frontier of LSM development : interfaces with other discipline.Session 3 : Uncertainties, quality controls, and correction techniques in model formulation, coding, parameters, forcing, and initial conditions.Session 4 : PUB and PUB activity in Asia.Session 5 : Needs for hydrological modeling: Where is the scientific frontier, which is the technical cutting edge, and what are the societal needs?
