Abstract

Suitable geological condition is favorable everywhere especially where it is associated with water flow, however access to optimal conditions is not always available. Where geological formation is weak and erodible, may lead to form dense valley and rough morphology which is called badland. Badlands are a common landscape formation in softer sedimentary rocks and clay-rich sediment and erosion is active in there. Beside of geology characteristics, these areas are sensitive to environmental change due to dense drainage systems and sharp slopes in barren areas Adsorbed sodium ion on the surface of clay minerals is one of the factors of dispersion, therefore, to investigate the chemical causes of erodibility and dispersion, the sodium absorbed ratio (SAR) criterion were used in this research, so the results showed that these units are dispersive.
