RT - Journal Article T1 - An Evaluation of Meteorological Drought in Fars Province JF - JSTNAR YR - 2002 JO - JSTNAR VO - 5 IS - 4 UR - http://jstnar.iut.ac.ir/article-1-79-en.html SP - 1 EP - 11 K1 - Meteorological drought K1 - Aridity K1 - Drought maps of iso-intensity and iso-duration. AB - Drought can occur at such times when variables such as rainfall depth, run-off, soil moisture, etc. show a deficiency, or variables such as temperature show an increase, or when ground water level shows a decrease in comparison with the average level. Therefore, drought can be evaluated with respect to agricultural, meteorological, or hydrological variability. In this research, considering the meteorological aspects, the method by Herbst et al., later modified by Mohan and Rangacharia, was applied in drought evaluation in Fars Province, Iran. Monthly rainfall measurements over a period of 21 years for 51 stations obtained from Fars Regional Water Board, were used in the analysis. Maps showing lines of iso-duration and iso-intensity lines were developed for the province. Based on the results, northeast, southeast, south, and southwestern parts of the province have the highest potential for being affected by drought events.
