Quality and Quantity Zoning Groundwater Resources in Plain Area Yasooj

Groundwater resources In Iran and many other countries which have similar climate are among the most important sources of water used in agriculture and as potable water. On the other hand, the lower contamination risk of these resources than the other methods of water extraction has boomed the use of such resources even in areas where the shortage of surface water is not felt. This research aims to map the spatial zoning of quantitative parameters including the surface and depth of groundwater and qualitative parameters including EC, TDS, pH, Cl-, SO4--, Na+, No3 and to evaluate the changes of those parameters during the study period (since water year of 2003-2004 to 2012-2013). Comparison of the maps of the spatial zoning of the groundwater depth during the period under study showed that in general the depth of water from the northern margin of yasouj irrigation network towards the south and from the center towards the surrounding areas is increasing.
