Nghiên cứu diễn biến hạn hán trên lưu vực sông Hồng - Thái Bình bằng bộ dữ liệu khí tượng, thủy văn khôi phục từ mô hình kết hợp WEHY-WRF

Abstract

This article presents the results of  applied research of the Hydrological - meteorological combined model named WEHY-WRF to calculate recovery processes precipitation and flow across the Hong - Thaibinh River Basin, including part in territory of China and Laos. From the recovered data, conduct evaluation studies on the  drought  development  across the basin through the calculations, analyses the evolution of the indicators of  Standardized Precipitation Index (SPI) and  Streamflow Drought Index (SDI ) over space and time, from 1960 to 2015. 

Key words: WEHY-WRF model, restore data, global data, indices SPI, SDI, Hong - Thaibinh River Basin.
