Drought impacts on ground water resources in shahrekord aquifer, Iran

Abstract

Ground water, according to higher reliance coefficient and less fluctuations, has been used for many years. Precipitation is a major supplier of underground water resources and aquifers. So any changes in rainfall amount fluctuate underground water table depth. Occurrence of drought is the most important reason for the decrease of water table. To analyze the role of drought on underground water in Shahrekord plain rainfall and water table level were used during 1984-2008 period. The resualts shows a strong correlation between precipitation and water table. The Pearson correlation coefficent (r) is 0.80. The results showed that the water volume of Shahrekord plain greatly depends on the rainfall. So drought event causes the water resources crisis in this region. © SGEM2011 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.
