Abstract
The importance of scale issues in geomorphic studies is the definition of wide variables in the analysis of levels with different scales that are projected according to goals and abilities. Considering that in sedimentary cell systems, there are processes that operate on a wide range of scales, it is important to determine the appropriate scale for studying these processes and their forms. In this study the coasts of Hormozgan province due to the diversity of landforms and coastal processes in its western and eastern parts was investigated. This coastal is divided into 6 cells and 17 sub cells based on geomorphologic unit and wave and currents pattern. 1: 25000 topographic map, 1: 100000 geology map, LandSat 5 satellite images, hydrodynamic data, wind, hydrology and large port dredging and sedimentology data were used for this purpose. This data was analyzed in ArcGIS 10.2 and coastal environment were classified based on common features of the form and process. Also an appropriate scale was determined for studying littoral cells based on our aim. The results indicated that all of these scales should be considered to determine management strategies. Studies have shown that scales used for coastal study include system scale (large scale), subsystem scale (moderate scale) and landform scale (small scale). temporal and spatial scales in the form of a littoral cell are in a moderate scale. It can be concluded the medium scales are usually of greatest interest for coastal management.
