Comparative study of the shape and amplitude changes using the sinusity index Karst forms Kermanshah Province

Surface roughness with different lithology, dramatically changes the slope of the range and type of show Land form. The curved lines on topographic maps, one of the important elements in detecting these changes. sinuosity indicators, including indicators that can be made using the slope of a range of features on topographic maps show. The purpose of this study was to evaluate the changes in shape and slope of a range of limestone and nonlimestone using the sinuosity index in Kermanshah province. Type of applied research and statistical methods to review, field and analytical use of physical tools such as topographic maps, geology, geomorphology, korvimeter and GPS. Research results show that statistical methods to examine the range of topographic map, to achieve an index that can be detected with the type genus of the map, complete, valid and not usable. So you cannot use sinuosity index and the topographic map, to change the type of formations realized.
