(Erosion Prediction in Ungauged Basins: Integrating Methods and Techniques (Proceedings of Symposium HS01 held during IUGG2003 at Sapporo, July 2003), IAHS Publication No. 279, 2003, pp. 145–150).
Prediction in Ungauged Basins (PUB) is a recent initiative undertaken by the International Association of Hydrological Sciences (IAHS). As the biggest developing country in the world, China has to face the difficulty that many basins are ungauged or, at best, imperfectly gauged. This paper discusses major directions of research on PUB in China, and in particular the unit hydrograph methods applied to the prediction of flooding in ungauged basins in China. Moreover, this paper describes the advantages of using new systematic theories and methods that rely on computer technology and remote sensing. Numerical simulation models will be the new way for PUB. This paper suggests a comparison study between well-gauged and ungauged basins. Furthermore, some new theories and technologies used for ungauged basin simulation are appraised, such as distributed hydrological modelling, remote sensing, and four dimensional data assimilation systems. Finally, some thoughts on hydrological studies in ungauged basins are presented.
