متن يادداشت

To estimate places the amount of monthly precipitation due to the complexity of the phenomenon and the lack of information and sufficient physical and mathematical equations governing on the subject, usually spherical models are useful, that independent of the physical parameters affecting the phenomenon and The governing equations between them. Geostatistical interpolation is a set of statistical techniques for analyzing spatial data. In general, this thesis to study the dispersion of spatial data and simulation for areas without data. In recent years using of this technique to predict the hydrological characteristics. this technique is suitability for modeling in water engineering science. This study consists of three basic steps. The first step involves selecting classification to extract the best variograms calculated from the observed data and model variograms obtained favorable and tries to communicate between the variogram of the same month of the different past years. The second step after determining the best variograms, mainly between theoretical models, Gaussian, spherical and exponential are selected, according to the variogram model, then go to processing half of the experimental variograms and start to kriging operations. Given that in most months of review use of the spherical model.In the third step for the calculation, the Cross Validation is done each month separately. The output from these three basic steps, a spatial distribution of the region with all stations intended to be presented as a graphical map. In order to achieve this model, the monthly precipitation data between Persian date Farvardin 1387 to Esfand 1391 in 33 rain gauges have been used Ajichay Basin.The results show that the spatial, ordinary kriging calculations is ability to predict the relationship between the amount of monthly precipitation. variogram parameters have meaningful relationship. This relationship not show particular trend. It also compares the results of kriging calculations, projections of each month, shows that rainfall in the catchment area independent of the other months. But rainfall in the catchment area have dependent of the same month of the different past years
