Abstract

In this study RAINFALL EROSIVITY in GHAZVIN PROVINCE has been modeled and estimated through the application of FOURNIER MODEL and based on a 20-year statistical period (1368-1388) of meteorological bureaus (synoptic, climatology and rain gauge) and Regional water organization. To generalize point data of erosivity strength ratio in FOURNIER MODEL to the surface, in GHAZVIN PROVINCE, KRIGING and IDW methods have been used. In addition, to evaluate INTERPOLATION methods, cross validation and RMSE criterion have been employed. Accordingly, IDW method was identified to be more appropriate, due to the less error in mean chi-square (6.59) than KRIGING method (7.23). Also, Variogram with exponential model was used as the proper model for fitting. Modeling and evaluation of RAINFALL EROSIVITY in GHAZVIN PROVINCE were performed by location analysis function of Geographic Information System and GS+ software. The data indicate that north and northeastern regions and some parts in the southwest of the province, with minimum/maximum rainfall of (216.1-776.9) and (205.2-751) respectively, have the highest RAINFALL EROSIVITY ratio. These changes could be influenced by rain distribution patterns, the amount of rainfall, and the topographical characteristics of the region. Ultimately, 4 different regions with insignificant, low, medium and high erosive ratios were distinguished in GHAZVIN PROVINCE.
