This study tried to reveal relationship between surface relief and denudation in granitic erosional basins such as the Chuncheon, Wonju, Yeongju and Boeun Basins, with relief analysis, petrological properties and incision rate distribution. The highest and lowest surface relief was found from the Wonju and Chuncheon Basins, respectively. The Yeongju Basin can be characterized by high elevation and gentlysloped low relief. The Boeun Basin showed moderate surface relief. The low relief in the Chuncheon Basin can be attributed to petrological properties less-resistant to weathering process as well as to geomorphic properties such as confluence of large rivers. With petrological properties resistant to weathering process, high incision rate was thought to be responsible for high relief in the Wonju Basin. Less-resistant rock and high incision rate due to geographical proximity to the uplift axes were regarded as main causes of gentlysloped low relief in the Yeongju Basin.

Taluses are usually developed at the boundary between slope and gravel beach in the Southeast Coast of Seodo, Dokdo. The largest one is about 50m long. Some valleys on a thick tuff layer are dissected by streams, because tuff is less resistant than trachyandesite to erosion in this coast. Therefore, a plenty of debris are supplied from these valleys. In this slope, we established three study transects (A, B, and C). The lower portion of these taluses is not dissected by wave erosion. It is related to the shallow strait about 2m depth between Dongdo and Seodo, because wave sediments delivered from offshore continuously fill the strait. The typical landscape of the taluses in the study area is presumed to have been shaped by geomorphic processes during the Quaternary. That is, the bottom of the talus is composed primarily of the debris originating from the glacial period, some of which are covered with the sediments delivered from the surrounding valleys during the postglacial period. The main factors that affectedthe development of these taluses are considered as follows; bedrock characteristics of the slope, density of lineaments, slope gradient, vegetation cover, and soil distribution.

Naeseong-cheon River with beautiful sandy channel showed riverbed landscape covered with vegetation after construction of Yeongju Dam. In this study, the changes and causes of the riverbed relief and channel landscape of Naeseong-cheon River before and after the construction of Yeongju Dam were analyzed. Precipitation was decreased from spring to early summer, in 2014. This drought led to increase of riverbed vegetation cover in 2014 and vegetation cover showed peak in 2015 when flood discharge was low. Since 2016, however, some of vegetation cover was removed by sand bar erosion due to increased discharge during flooding. Thereafter led to complex riverbed relief in Naeseong-cheon River and riverbed vegetation cover with a slight decrease has been maintained until now.

As part of an effort to popularize geomorphology, a course called “Traveling Lanforms in Korea” was developed and opened at Chungbuk National University in 2021. The lecture materials are posted on the online Liberal Education courses of Chungbuk National University; provided as a Lifelong Education content through K-MOOC; and provided to nine national universities through the Base National University Credit Exchange System. The contents of the lecture focus on the geography of the middle and high school curriculum, including mountain landforms, plateaus, granite topography development, mountain rivers, coastal erosional and depositional forms, volcanic landforms, and karst topography. Some portions of this lecture, representing important landforms of Korea, were filmed. In the future, it will be possible to develop and proceed with additional lectures that include geomorphological topics, which are not currently included in this lecture, such as rivers at plain, alluvial fan, arid landforms, glacial landforms, and periglacial landforms. In addition, it seems that new subjects such as landforms of geopark in Korea, are necessary as well. Also, in relation to the high school credit system, it is thought that physical geography and geomorphology-related lectures should be developed in the near future.
