Abstract

Erosion and sediment creation in a region is largely dependent on its climate and weather, because weather impacts on vegetation condition also effect on soil creation phenomenon. However, there are two map formats (raster - VECTOR) in GEOGRAPHICAL INFORMATION SYSTEM (GIS) software and with regard to the type of the map, the correct format should be used to produce maps so that use them for final analysis, the accuracy of the researcher increases. In this study, the meteorological factors were obtained using MPSIAC and EPM method for both formats (raster - VECTOR) in Nashtaroud watershed basin and has been employed in calculations. The results show that considering that the meteorological data are type of dependant data, preparing them through RASTER format will lead to less error than VECTOR format in final analysis(according to when was used VECTOR format researcher is forced to consider a weighted average for works units While these works units can have different condition in terms of meteorological score that in the loss of these differences makes incorrect predictions erosion in watershed basin) which subsequently will have lower percentage of error in estimating the amount of special erosion and sediment. Also, amount of this difference in MPSIAC and EPM method were observed in A1-1-4-1, A1-1-4-2, A1-1-5, A1-1-6-1, A1-1-7-1, A 1-1-7-2, A1-2-1-2, and A1-2-1-3 sub-basins of Nashtaroud watershed basin. In this sub basin of expressed, score of climate varies around 2 to 3.5 and in total basin this difference is around 0/5 score. That this result can be effective for offer methods of control of erosion.
