The WRF meteorological model was established based on the physical characteristics of the basin and tested with the measured rainfall data series of the meteorological meteorological stations, combined with Japan's APH global rain data set. Copy. Hydrological model WEHY basin is built based on basin parameters such as topography, land cover, soil ... The model is tested based on the actual data series collected in the territory. Vietnamese and Chinese soil. The results of the Thao river flow data have been restored since 1950-2008 with quite good reliability and can be used to calculate, analyze and study hydrological characteristics, flow in the basin.
