Analysis of the Change in Ground Water Depth of K？r？khan District with GIS

The rise of the groundwater in the plant root zone causes the decrease in agricultural production. In addition to the decrease in yield, it can cause problems such as salinity and sodication. To achieve the expected benefit from investments made for irrigation purposes, groundwater should be continuously monitored and maintained at the levels foreseen in the projects. In this study, the depth of the groundwater measured by DS？ was used in 60 observation wells known as coordinates in Hatay K？r？khan district from 2004 to 2016. In 2004, 2008, 2012 and 2016, groundwater contour maps were prepared for July when the irrigation is the most intensive period, and changes in groundwater depth investigated with ILWIS GIS software. Fluctuates in groundwater depths were compared with the amount of irrigation water taken into the network and the effect of the amount of irrigation water used on the depth of the groundwater was investigated. As a result, an important relationship was found between the depth of groundwater and the amount of irrigation water received to the network, and it was concluded that planned water distribution and application could control the groundwater level
