Abstract

Erosion and sedimentation are among the natural processes continuously changing the land surface. This deformation may affect the development activities of the coastal areas such as Bandar Anzali region. In order to evaluate the potential of erosion in the region, various methods of zonation mapping were reviewed. The region was divided into a number of grid lines and the weight of each grid was measured. The computer program Arc-GIS was used to calculate the weighing factors of each cell and finally to draw the zonation map. In this regard, five factors including lithology, slope angle, fault types, drainage pattern, and land-use (vegetation) were considered as major affecting factors on the erosion phenomena. The results showed that the effect of lithology and land-use are higher as accompanied by the effect of fault type and slope angle, and the effect of drainage pattern is most noticeable in mountainous areas. The geochemical characteristics of the sediments in Anzali wetland indicate that the percentage of SiO2, Al2O3, and CaO2 is higher than that of other elements such as FeO, MgO and MnO. These sediments represent the lithological setting of the provenance region of the originated sediments.
