3-D map producing for groundwater level using Kriging interpolation method

Abstract EN

Groundwater is one of the main water resources in the arid and semi arid areas.

Due to increasing demand for water in different purposes these resource management is very important.

Prediction of groundwater depth and elevation is useful for management of the scarce water resources.

The application of the spatial statistical technique (kriging) is used in this study as estimation method, The data set consists of groundwater levels measured at about 43 wells were selected in the studied area in May 2010, in an area (1350) ??2 a part of Baghdad City.

With the use of measured elevations of the water table, experimental semivariograms were fitted into many models as linear, spherical, exponential and Gaussian semivariogram.

The finally selected models were used to estimate groundwater levels and estimation variance (which express the accuracy of the estimated groundwater levels) to develop corresponding contour maps.
