Evaluation of Iinterpolation Methods to Draw Isopiez Groundwater Level(A case study in Garebaygan plain, Fars Province, Iran)

Groundwater management is depending on suitable monitoring of groundwater table in spatial and temporal. Owing to this drawing isopiez can help to decision makers. Limitation of piezometers for drawing groundwater level is a problem for groundwater management. There are many methods to draw groundwater contour map, but it is not clear which one is the best. In this research Ordinary Kriging (OK), Simple Kriging (UK), Natural Neighbour (NN), Spline (SP) and Inverse Distance Weighted (IDW) were used in geography information system (GIS). The result of these methods compared with many filed measured points in the aquifer. The best method for interpolation groundwater table evaluated for this area.
