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.
