Wetness index obtained from topography data of Woogak Mountain was compared with chemical alteration index(CAI), clay minerall contents of rock, and magnetic susceptibility changes of outcrops, and they show a close interrelationship. It is shown that the wetness index can be used as a quantitative indicator of the weathering degree of rocks. Moreover, wetness index simulate quantitatively the hydrologic condition of the local area. Therefore, it is anticipated that wetness index can be used as the data that calculate the weathering speed of rock and weathering grade in the study of weathering sensitivity of rock.
