In basic studies of water and soil resources, recognizing the drought indicators and evaluating them can achieve effective management of water resources and better evaluation. Increasing population on the one hand and rising temperatures on the other hand necessitate the need for more human societies to recognize and predict drought as one of the extreme events resulting from climate change. In arid and semi-arid countries such as Afghanistan, where all water resources depend on snow and rain, the issue of drought is an important and recognizable phenomenon. For this purpose, the purpose of this study is to assess drought using SPI, SDI and RDI indices downstream of Harirod catchment. The study area is located in Harirod basin and its area is 31402.6 square kilometers. This basin is located at 62 degrees and 20 minutes’ east longitude, 34 degrees and 45 minutes’ north latitude in the northwest of Afghanistan, which shares a border with Turkmenistan from the north and Iran from the west. In this study, DrinC and DIP software packages developed by the National Technical University of Athens, Greece and Tarbiat Modares University of Iran in 2013, respectively, were used.
