Abstract:

This article presents the data of the variation pattern of flow discharge of the arteries. To assess the water resources of the arteries in a multi-year document, mathematical model was used to calculate the annual flow of meteorological data from 1980 to 2016. Meteorological changes are also applied when calculating climate change in 2035 and 2065 according to the scenario RPC 4.5 given by Ministry of Natural resources and Environment in 2016. The results show that the current water resources of the arteries are about 239,35 million m3/year, accounting for 0.54% of the water resources of the four provinces in Central Highlands, when considering climate change by 2035, the water resources of the arteries increased by about 9% compared with the current state.
