The Effect of Climate on the Different Levels of Groundwater in the Khanaqin District

Abstract

       The characteristics of the groundwater, including the rise and fall in its levels, its productive capacity and the movement of the groundwater, are affected by natural factors that have a major and fundamental role in the different characteristics of groundwater, especially the climate factor, so the topic of the study has come to study the importance and impact of the climate factor in the different groundwater level in the Khanaqin district, especially rain and the amount of evaporation factors. For the purpose of proving the hypothesis that climate changes have an impact on the different characteristics of groundwater in the Khanaqin district, mathematical climate equations have been used, which is the (penman-monteith equation) prepared by the Food and Agriculture Organization of  The United Nations through the (Gropwat 8.0) program that requires the presence of two basic variables in its application are the effective rain and the amount of actual evaporation.  For the purpose of the work of climate water balance to know the volume of water surplus, water deficit and the size of the groundwater recharge through the results obtained, and the work of digital spatial mapping using the Geographic Information Systems Program (GIS10.5) for the characteristics of groundwater and mud  Climatic Views In order to know the area represented by the change of groundwater levels in the Khanaqin district and to demonstrate the existence of a causal relationship of its lack between climate variables and the characteristics of groundwater, a Pearson correlation was used to extract the correlation coefficient between climate variables and the characteristics of groundwater to extract the correlation coefficient between the above-mentioned variables and test the level of significance. Through the previous scientific steps, several results were included in the study.
