    Abstract


    The objective of the study wasto calculate drought basedon meteorological data (rainfall, temperature and humidity) at meteorological stations in the areafrom 1984 to 2016. Inthis study, we used the drought index - K (based on the water balance) to assess the level of the drought with4 degrees:none, less, moderate, and extreme drought. The distribution of rainfall (R) and evapotranspiration (E0) were interpolated and extrapolated by using GIS to build drought zone maps. Results showed that Binh Thuan is adroughtprone areabecause of very few rain in the dry season. Besides, the drought was fluctuating with time and space. In recent years,extended severe dryness occurred,concentrating in the Eastern Coast of theprovince in dry seasons.
