Abstract

The drought status as a natural hazard is very important problem in different areas. It is necessary to develop plans to deal with drought and risk management. There are lots of indices for drought assessment based on climatic quantities. Simultaneous occurrence of drought indices can be a useful framework for conformity assessment profiles. The aim of this study was to compare two methods, TOPSIS RANKING METHOD and Standardized Precipitation Index (SPI) for drought condition in KHOUZESTAN PROVINCE and their performance in this review. In another part of this study, the SENSITIVITY of TOPSIS method to determine four climatic parameters are affecting climate drought or wet. In this study, it is found that these two methods to determine the intensity and condition of drought are good and have similar performance but for measure the intensity of wet, SPI is not useful. In fact, this method just determined that the target year is wet or not. For example, the lowest value for this index was -3.04 which is related to Abadan station at 2011 and this number indicates severe drought. The highest value was 1.33 which is related to Ahwaz station so it is located in normal (wet) category. TOPSIS RANKING METHOD in addition to determine the intensity of the drought can also present the condition of wet years numerically. According to the calculations, 2011 was the driest year among all stations and 1992 was the wettest year among all stations. To determine the SENSITIVITY of TOPSIS method, it was found that the most sensitive parameter among the climatic parameters is related to the number of rainy days and low SENSITIVITY is for relative humidity amongst all the parameters.
