  • This research aimed to analyse geomorphic resources of Mt. palgong(in Daegu city and Gyeongbuk province) through some field surveys, and then to clarify geomorphic features. The main results are as follows. 1) The geological boundary of the south slope(granite) is more clear than one of the north slope(granite bedrock and metamorphic sedimentary rock). Small basins are along with fault line between granite bedrock and metamorphic sedimentary rock. 2) It is estimated that relatively big valleys on the north slope are due to local climate, geomorphic and geological features. 3) Tor, sheeting joint, gutter are well developed both on the south slope and on the north slope, however the development of polygonal cracking and boulder stream are more dominant on the south slope; river cliff, pool, waterfall are more dominant on the north slope with valleys that well developed. 4) Scenic geomorphic landscapes are mainly developed in Dongsan valley and Chisan valley on the north slope. 5) There are many interesting geomorphic resources in the viewpoint of storytelling in Mt. Palgong. So the specific design to utilize such resources is required

  • Mt. Apsan is well known to be one of the most popular tourist sites around Daegu. Annually, more than 16 million persons visit Mt. Apsan. Although, in the mountain there are varieties of geomorphic and geological resources, there has been less concern to utilize the resources for geo-tourism. For example, there are about 10 valleys within Mt. Apsan and various landforms are scattered around the valleys. In this context, this study, based on field surveys centering around Gosangol valley, Anjiranggol valley and Dalbigol valley, focuses on exploring ways towards developing Mt. Apsan as an example geo-tourist site. The main findings are as follows: 1) The main landforms of Mt. Apsan include river cliff, cavern, free face, mud crack, ripple mark, fold, sheeting joint, talus, alluvial fan, pot hole, fault line, gnamma, columnar joint and metamorphic rock. 2) The guide notes on the landforms are developed. 3) In order to raise a learning effect of visitors on geomorphic resources, 9 nature trails are designed according to valleys and the length of visitor's stay.

  • In this paper Gumho drainage basin is divided into six geomorphic units (Bohyeon, Palgong, Biseul mountainous areas and Yeongcheon, Gyeongsan, Daegu basin), and physical geographical background and distributional characteristics of geotourism resources in each geomorphic unit are examined. Most(32 sites, 78%) of geotourism resources in Gumho basin reflect geomorphological environment, rest(7 sites, 17%) of them reflect geological environment. There are three geomorphological resources in Bohyeon mountainous areas, eight geomorphological resources in Palgong mountainous areas, and five geomorphological resources and one cultural resource in Biseul mountainous areas. There are two geomorphological resources, one geological resource, one biological resource, and two cultural resources in Yeongcheon basin. Among them one biological resource and and one cultural resource reflect local geomorphological environment. In Gyeongsan basin are there one geomorphological resource, three geological resources, and one biological resource, but one biological resource reflects local geomorphological environment. There are eight geomorphological resources, two geological resources, and three biological resources in Daegu basin. But two biological resources among them reflect local geomorphological environment.

  • This study investigates the geomorphic changes and Bed Relief Index of the river downstream of the Yeongju Dam by Nays2DH, a two-dimensional numerical model, in order to grasp the dynamics of the downstream river while applying various flow patterns such as pulse discharge. It shows that the geomorphic and the bed elevations changes are the largest under the condition of the normalized pulse discharge. The total change in the riverbed is 29.88 m for uniform flow, 27.46 m for normalized hydrograph, 29.63 m for pulse flow and 31.87 m for pulse flow with normalized hydrograph which result in the largest variation in scour and deposition. The Bed Relief Index (BRI) increases with time under conditions of uniform flow, pulse flow and pulse flow with normalized hydrograph. However, BRI increased rapidly until 30 hrs after the peak flow (14 hrs), but decreased from 56 hrs under the condition of normalized hydrograph. Therefore, the condition of normalized hydrograph gives greater dynamics than the condition of a single flood or constant flow, and the dynamics increase downstream than upstream, resulting in an effect on improving the environment of the river downstream of the dam.

  • The purpose of this study is to identify the geology, geologic structure, hydrogeology and geomorphic characteristics of the Nari Basin and establish the controls on the discharge of water 20,000~40,000 m3/day from the Choosan Yongchulso, Ulleung Island, South Korea. Pumice and lapilli tuffs showing well-developed stratification are the predominant rock types surrounding the spring. The spring shows a structure whereby discharge occurs along a lens-like erosion cave formed by differential erosion of strata comprising tuff or pumice tuff. The Choosan Yongchulso is located at the point where the planation surface of the Nari Basin' ends and steep slopes begin. The basin is bounded on all sides by these steep slopes, except in the north, where the Choosan Yongchulso is located. Given these geomorphic characteristics, the Choosan Yongchulso is regarded as the ultimate outlet of the basin catchment area.

  • Silgyeong sansuhwa (Realistic landscape paintings) are drawn in Korea since 17th century. It has characteristics of more realistic description of landscape than painting from previous periods. Kim Hong Do's 'Haedong Myeongsan docheop (The album of paintings of famous mountains in Korea)' has been recognized as fine example of realistic description of geomorphic landscapes. Kim Hong Do and Kim Eung hwan did official travel to Gwandong and Geumgangsan area by order of King Jeongjo in 1788. As a result of that travel they draw about 100 piece of landscape painting. About 60 pieces of the paintings are still remaining. These are open to public by Korea National Museum in 1996. 14 pieces of painting, Daegwanryeong and Gangneung, Gyeongpo-dae, Hohae-jeong, Gahak-jeong, Cheonggan-jeong, Mun-am, Mangyang-jeong, Wolsong-jeong, Neungpa-dae, Naksan-sa, Mureung-gye, Gyejo-gul, and Hyeonjong-am, are analysed in this study. Coastal depositional landforms, like lagoon, sand beach and spit or barriers, erosional forms, like sea stack, sea cliff and sea cave, depicted in the paintings are analysed. In addition, structural landforms, colluvial landform and bedrock incision form by the running water in mountain area were analysed and weathered forms of granite and excursion to karst cave also discussed. It is found that sea arch in the printing destroyed since 1788, though exact position and reason is still unknown. There are strong need for discovery and identification of geomorphic landscape resources, for applied geomorphological studies and for prepare educational materials for non-face-to-face education. It also be emphasized that it can be used of the course work materials for future education using augmented reality and virtual reality technology.

  • This paper provides a new geomorphological approach for survey of potential flood damages and for preparation of cartographically accurate flood maps. floods are possibly the worst disasters we have recorded in he past and may expect in the future. Interpretation of aerial photographs of river basin enables us to determine the nature of floods by investigating the maximum extent of inundated areas in the past. Most of the typical dangerous spots, highly susceptible for flood disasters can be systematically identified by analyzin lithologic, structural, and geomorphic cycle.
