Study of multisite streamflow generation model in Taiwan

In Taiwan, the streamflow in different periods reflects striking climate characteristics. Therefore, the climate characteristics should be taken into account in a streamflow model to give a more accurate simulation. In this study, a climate-dependent streamflow generation model is proposed through characterizing the streamflow by the climate properties of Taiwan. Some statistical approaches are further invoked to develop the multisite streamflow generation model. The multisite streamflow generation model, unlike a single-site model which fails to account for the global basin, can reveal the correlation of flows at different sites. Excellent results are obtained by applying the proposed model to study the tributaries of Danshuei river basin in Taiwan. Accordingly, an extension of the multisite streamflow model based on the climate characteristics to water resources planning for other basins in Taiwan will be reasonably expected.
