Abstract:
Climate change and intense human activities have an important impact on hydrological cycle and its spatial and temporal evolution. The previous research results can no longer truly reflect the hydrological changes in modern circumstances. As the representative of conceptual models, the Xin'an river model is no longer suitable for the simulation of the comprehensive hydrological elements in the basin, so a lot of basic research work needs to be strengthened. To solve this problem, this paper takes the water resources experiment station of Xin'an river as an example, and expounds the application of the basin-nested enhanced observation scheme in practice. Based on the original facilities, an integrated observation field for prototype basin and slope land hydrology, a nested enhanced observation basin, a center for comprehensive hydrological experiment, analysis and testing, and a remote receiving center will be newly nested. Results show that the scheme can effectively increase data resource types and expand coverage, provide data for both the development of a new-generation hydrologic model system and the construction of an atmospheric-hydrological-ecological integrated model.
