Daily flow hydrograph simulation using regional flow duration curves for ungauged region of Dongjiang basin;

Research in un-gauged basins has become more and more popular all over the world.

Predictions in Ungauged Basins(PUB) is the theme of International Hydrological Decade,the core of which is runoff calculation.

The FDC calibration method for regionalization of hydrological models in ungauged basins adopting regional flow duration curve as calibration objective,serves as a new approach rather than the parameters\' correlation method with the focus on trying to search relationships between the parameters of such models and catchment attributes.
