Abstract:

Based on the observed, simulated and forecasted meteorological products derived from new materials, new technology, new method of the modern meteorological operations, the forecasting platform of precipitation and hydrology in small and medium watershed was integrated with Micaps3.1 system. Combined the observation of hydrology and forecasting models, the precipitation and hydrological parameters were elaborately forecasted and displayed on the same platform. This paper introduced the main function, the module design features and the main system interface conditions of Micaps3.1, firstly. Secondly, the deficiencies of Micaps3.1 were improved to meet the actual needs of small and medium watershed forecast and the elaborate forecasting platform in small and medium watershed was developed, and we focused on the workflows and work contents of system, key technology and related algorithms. Finally, the system was applied to hydrology forecast in Zhanghe reservoir basin, and the forecasting effects were tested based on the observation and other hydrology processes. In addition, the digital information of basin including the basin boundary and river network was extracted by using GIS technology based on DEM data. The system had been used widely in meteorological bureau of many provinces and cities, reservoirs, power plants. The results showed that the system was easy to transplant and simple to operate, and the layout was reasonable, which had a certain promotion significance and application values.
