Abstract

The rainfall is an important parameter in the water resources research. Hence it is necessary to available an adequate raingage network that enable an exact estimate by its rain measurement.In this research for optimizing the KHOZESTAN PROVINCE raingage network, between the different estimating method, GEOSTATISTIC method and invert distance method compared. The indicator for comparing methods is Mean Square Error (MSE). Mean Absolute Error (MAE) and Mean Bias Error (MBE) that are result of Crosse validation technique.The data set include of monthly rainfall of 79 number of raingage network. Result of studies showed that the KRIGING METHOD estimate the rainfall with high accuracy. Thus KRIGING METHOD used for optimize the rangage network. Because of none correlation between height as a helping variety and monthly rainfall, the cokriging method is not an adequate method. Gaussian model between the available fitting models had the best fit.to study the addition raingages, using tow evaluation indicator of cross validation technique, S number of raingage that were estimable by other point of network had been suggested for removing from raingage network. Also for decreasing the estimate error of monthly rainfall in the new raingage adding stage at the region, by evaluation the kriging estimate error, three new point for create the rangage were selected.
