The theory of quantity of money in that there exists a one-to-one relation between money growth and inflation, that means a highly and a continuous of rate of money growth leads to a high rate of inflation. During the recent years with the divergence of growth of money from inflation in the Iran economy leads to the opinion that an interruption has occurred between the growth of money and inflation. By the way, the main objective of this paper is to investigate the relationship between the growth of money and inflation by using the data of the 1350-2005 periods. The model that was used to investigate the relation of growth of money and inflation is a model that stemmed from quantity theory of money and is combining with the Phillips curve to model inflation to be linked trough expectations. The results revealed there exist a stable relationship between the growth of money and inflation and this states that in the long run one percent increase in the growth of money will increase inflation by 0.89 percent.

The complex behavior of the aquifer system is studied by solving a set of governing equations using either analytical or numerical methods. Numerical techniques like finite difference method (FDM) is being used to solve differential equation in some simple cases. Recently Meshless methods are developed in engineering fields. They are used for solving differential equations in both simple and complex cases. As this methods needs no meshing or re-meshing on the domain the shortages of meshing disappeared. Less studies already performed in groundwater flow modeling with meshless method. In this study Meshless local Petrov-Galerkin with moving least squares approximation function and spline weight function is used to model groundwater flow in Birjand unconfined aquifer in steady condition. The computed surface of groundwater with meshless local Petrov-Galerkin method is compared with the results observation. The results are found satisfactory. The relative mean error and root mean square error of computed groundwater surface from Meshless Local Petrov-Galerkin are 0.0002 and 0.483 respectively.
