Spatial Variability Analysis of Electrical Conductivity (EC) of Irrigation Water Used in Agricultural Production: An Example of Dalaman-Muğla

45113

In this study, it is aimed to determine the electrical conductivity (EC) in the agricultural irrigation waters in an agricultural production area determined as test area, to generate the spatial distribution map in the region using geostatistical methods and to examine the regional changes. In this context, water samples were taken from three different regions where agricultural production have been intensively carried out in Dalaman and pH, EC, anion (CO_3^-2, HCO_3^-1, Cl^-1 and SO_4^-2) and cation (Ca^+2, Mg^+2, Na^+1 ve K^+1) analyzes were performed in these samples. In the geostatistical analysis, semi variogram and Ordinary Kriging methods were used to analyze the EC data obtained from sampling points with descriptive statistics. Thus, EC models of the region were extracted and accuracy analyzes were performed and the models were compared. In the study, spatial locations of the wells and distances between each other were calculated by using geostatistics analyzes and distribution points and separation points between regions were determined with very low error rates. As a result of the research, it has been determined that the electrical conductivity of irrigation water increases depending on the topography of the land from north to south.
