The objective of this study is to forecast meteorological droughts in the Mekong Delta using Artificial Neural Networks (ANN). Standardized Precipitation Index (SPI) was first calculated to determine 3 and 6 - month droughts for current period of 1980-2013; and SDF (Severity – Duration – Frequency) curve was then established. ANN for meteorologi...
