Abstract

DROUGHT is one of the natural and hazardous phenomenon which occurs periodically due to the lack of humidity resulting from decrease of precipitation. In this research, it is tried to study the pervasive DROUGHTs in GHAZALOZAN water basin during the last two decades. To obtain the research objectives, the data of climatic stations with statistical period of 1991-2011 have been used. at the first step, the general characteristics of precipitation and the basin discharge were examined. At the next step, Further calculations were performed by using MATLAB, Excel, GIS and Surfer softwares. Then based on MORAN INDEX I, the map for spatial distribution of abundance, occurrence probability and spatial autocorrelation of discharge, DROUGHT and rainfall were drawn. Analyzing the DROUGHT maps showed that there exists a significant relationship between discharge DROUGHT with precipitation in GHAZALOZAN area. Accordingly, the results of analyzing Moran spatial autocorrelation indicates that the impacts of discharge DROUGHTs and precipitation has formed more the above pattern in southern part of the basin, while in other areas, the discharge draughts and precipitation have a random pattern.
