Abstract

A country’s water resources, especially GROUNDWATER, is a national treasure. For optimal use of available water resources comprehensive planning is necessary to make informed and accurate understanding of this important component of water resources will not be possible. The purpose of this study was to evaluate the accuracy of INTERPOLATION techniques for spatial zonation of quantity parameters (water table and depth) and changes in these parameters for a ten years period base on the data collected from peizometric wells of Alashtar plain in Lorestan province, several geostatistical approaches such as simple Kriging, ordinary Kriging, simple CoKriging and ordinary CoKriging as well as other deterministic INTERPOLATION methods includes Inverse Distance Weighing (IDW) with different powers were investigated. After quality control and normalization of the data, the VARIOGRAM was drawn. According to the Residual Mean Square Error (RMSE), below, the most appropriate VARIOGRAM was chosen. Then validation approach and Mean Absolute Error (MAE) criteria were considered to determine the most appropriate INTERPOLATION technique. The results showed that among the all methods, Kriging method is most suitable for zonation of GROUNDWATER depth, simple CoKriging is most suitable for zonation of GROUNDWATER table (using H variable).
