چکیده:

With taking discrete sampling from the water resource parameters in quantity and quality and the use of procedures of turning discrete spots to connected area one can study the process of the surface changes of selected area. There are different procedures for turning broken discrete spots to continuity of areas such as procedure of statistic ground which conclude Kriging procedure, Inverse Distance Weighting (IDW), Radial Basis Functions (RBT), and Local Polynomial Interpolation, Global Polynomial Interpolation, Co-kriging. In this research with the use of Kriging, IDW and RBF procedures the curves of equal level of underground water is drawn by GIS. And with the application of statistic signs such as Mean Absolute Error (MAE), Mean Absolute Relative Error (MARE), Root Mean Square Error (RMSE), MBE, Coefficient of Correlation and also the graph of the average of the percent dispersion of absolute value of relative error, the researcher has compared these procedures and drawn the direction of the flow of underground water which is the major relevant issue to Hydro geologic studies in Dasht Razan-Ghahavand.
