Abstract: 
Environmental crises and loss of natural resources are among the main causes of the establishment of environmental management systems. The optimal management of natural resources requires the assessment and classification of environmental and ecological potentials. Sand arrow is one of the most important accumulations landforms in Njarabad Erg in the northeastern of Toroud village. In this research, the morphometric and morphological parameters of the sand arrows and increase of their volume in the one-year period were measured. Then, using the regression analysis method, the type, and intensity of the relationship between the amount of increase in the volume of the sand arrow and the morphometric and morphological parameters of the sand arrows were investigated and the models were presented to estimate the sand volume. Morphometric parameters include the length and maximum width of the sand arrow and morphological parameters include height, canopy diameter and crown diameter of the plant. These models can easily calculate the volume of sand arrows in the study area. The results indicate that the relationship between the amount of volume increase and the morphometric and morphological parameters of the sand arrows follows the linear, power and exponential functions. The results show the maximum linear correlation between the volume of the sand arrows with canopy diameter with the highest R2 (0. 807) and the lowest Std error of the estimation (0. 13). The results of this study, primarily inform environmental managers about the state of the sand arrows system and secondly, as a tool for serving environmental managers, express the trend and extent of the landscape of the sand arrows in different time periods.
