                         specifically, image processing for the control of the results of 
                         human actions on the ground. The engineering geology works to 
                         control and mitigate these actions. The digital image processing 
                         provides the results that can help in decision making process in 
                         this branch of science. The observation of the thalweg and the 
                         lines of runoff can help on the determination of a probably 
                         direction of a landslide occurrence. To deploy high-speed train on 
                         the proposed stretch, along the lines that is designed, it would 
                         be necessary to make a cut at the base of a talus deposit. The 
                         talus deposits are a real landslide hazard, identify them and 
                         indicate this direction of movements, shift more security for the 
                         planning of engineering work. The water that penetrates the soil 
                         can starts the landslide. CBERS 2B scenes were important in 
                         identify a talus deposit in the studing area, and allow the 
                         visualization of existing improvements around this deposit, as the 
                         Funils Dam and the Presidente Dutra highway, that crosses the town 
                         of Itatiaia in Rio de Janeiro. The directional filters are a 
                         useful tool to indicate the motions direction of the taluss body, 
                         and the digital elevation model (DEM) provided an easy viewing of 
                         the phenomenon. The lines of runoff could be seen applying the 
                         directional filter on CBERS 2B images. The Normalized Difference 
                         Vegetation Index process (NDVI) could indicate the lines of runoff 
                         after the aplication of directional filters.",
