Abstract
Drought can be considered as one of the most important consequences of climate change in recent decades. Which has severely overshadowed all natural societies, Organisms and humans. As a result, using the meteorological and hydrological indicators in drought, the severity and duration of drought can be expressed, the first step is to determine the best indicator for the area. One of the most important catchments in Iran is the Urmia catchment, which has been affected by drought. According to this issue, in this article, using rainfall and discharge statistics, RAI meteorological index and SSI hydrological index were calculated for 10 stations in Urmia catchment area. At first, these two indices were calculated in MATLAB software eand then in GIS by Kriging, interpolation method, SSI index was zoned compared to RAI control index, which showed the results of interpolation of appropriate compliance and overlap.
