Setareh Bagheri; Reza Tamartash; Mohammad Jafari; Mohammad Reza Tatian; Arash Malekian

Volume 75, Issue 1 , June 2022, , Pages 1-18

https://doi.org/10.22059/jrwm.2020.277200.1361

Abstract
  Plain ecosystem is highly vulnerable to environmental changes, and drought is the most famous ecosystem change driver that is difficult to identify after its occurrence. In this research, to study the slope of vegetation changes against drought, the NDVI index of MODIS images and the SPI index from 2001 ...  Read More

Volume 69, Issue 1 , June 2016, , Pages 141-154

https://doi.org/10.22059/jrwm.2016.61739

Abstract
  To identify an appropriate index for monitoring and evaluation of drought, rainfall data obtainedfrom meteorological stations of Ilam Province from 2000 to 2011 and MODIS satellite images with16-day intervals were collected and processed. The Standardized Precipitation Index (SPI) wascalculated based ...  Read More
