There are lots of depression forms and closed small hollows in the Karst landforms. For example, doline, uvalas, corrosion plains are belong to this case. In Karst surface it can be find that the gorges, meander caves, natural bridges, blind valleys, steepheads and dry valleys are well known landforms.

This study aims to provide fundamental data for further shape-factor research on karst by measuring and classifying the shape of surface topography in Hogye, Mungyeong. First, in the research area, there are 35 dolines and uvalas. Second, large uvalas are found in three places, including Gulnomjae in Bugokri, and Teotgol and Denjimigol in Urori. Third, there are 13 round dolines and 22 oval dolines. Next examining the cross section of dolines, there are 27 bowl shaped dolines, 2 plate shaped dolines, and 6 funnel shaped dolines. Fourth, most dolines lay over 200m elevation, which is ridge and top of mountain. Fifth, development direction of dolines resembles the strike direction of limestone in Hogye, suggesting that the development direction of limestone affects doline corrosion. From this situation, we can guess sinkholes of the doline would be linked with limestone caves by the underground water pipe. Three limestone caves, karren and dry valley etc. appear in the research area.
