We were to investigate the geomorphological environment of optimum location in the object of Bronze Age's dwelling site (hereinafter called dwelling site) of total of 205 units confirmed in the 'Cheonan Baekseokdong Relic Group' distributed in hill of the uppermost stream part in the watershed of Jangjae stream in Cheonan, Chungnam Province. To do this, we classified the hill of the object of investigation where dwelling sites were distributed as 8 units of slope micro-landforms and again by combining them with the grade of gradient of 5 units subdivided them into ultra-micro-landforms of total 40 units. On the foundation of this, in the viewpoints of 'gradients of each of micro-landforms' analyzed the 'number of dwelling sites' and 'dwelling site distribution density (measure: number of dwelling sites/1000m²) of 'Cheonan Baekseokdong Relic Group'. As the result, the optimum landform environment where the dwelling sites were located were found to be largely 5 units of ultra-micro-landforms - ① flat land of crest flat, ② gentle slope land of crest flat, ③ flat land of crest slope, ④ gentle slope land of crest slope and ⑤ semi-gentle slope land of crest slope. This analyzed material will be used from now on as basic material which can predict the distribution of dwelling sites of Bronze Age men who dwelled in the watershed of Jangjae stream.

The purpose of this study is to clarify the geomorphological characteristics of middle part of Korea. The purpose of this study is to clarify the fault structures in the Chukaryong Rift Valley. The Rift Valley has very significant meaning to interprete the development of Korean structural landforms. But till now the mechanism and processes of the formation of the Rift Valley are not clearly proved IMAGEM is very useful in this study. IMAGEM is developed by the Electromagnetic Instrument, Inc. and it covers $0.001{\sim}20,000Hz.$ Form the field survey data, it is certain that the faulted structures exist in the two points of the Rift Valley. But the Rift Valley is too long and braod to check the an evidences of the faulted structures.

The present writer have been engaged in research the Karst topography of Korea from the 1950's. Especially, I have studiedthe hollows indicated on topographical maps(1:5,000, 1:50,000) in library side by side with field survey. As the side by side with field survey. As the result, I came to a conclusion that all the hollows in limestone area are not always dolines. Based on case study, I classified the hollow landforms into 10 groups as follow. 1) Solution hollow 2) Volcanic hollow 3) Desertic hollow 4) Structural hollow 5) Meteoric hollow 6) Limnoic hollow 7) Minal hollow 8) Artificial hollow 9) Bursted hollow 10) Compound hollow I am asking advices of you all.

Gaemok, the place name of Uihang-ri, Sowon-myeon, Taean-gun, Chungnam, indicates a tombolo. This study estimated the Holocene sea level change and development process of the coastal landforms of the Gaemok and Hwanyeong Tombolos in the Uihang coast. The tombolos seemed to form at approximately 3.4 ka and the average sea level at that time was estimated to be higher than that of the present by ca. 1 m. The Gaemok area was a separated island from the Taean peninsula during the Holocene Climatic Optimum. At approximately 3.4 ka when the sea level rose again after the fall, the Gaemok area was tied to the land by formation of the Gaemok and Hwanyeong Tombolos. The falling or fluctuating sea levels after 3.4 ka have shaped the present coastal landforms.

The first paper on the floodplain in Korea was published in the late 1960s. In 1970s and 1980s the study on the floodplain and delta of Korea was led by Hyuck Jae Kwon(emeritus professor at Korea University) and Hwa-Ryong Jo(emeritus professor at Kyungpook National University). Kwon established the foundation of the study and Jo analyzed the alluvial landforms microscopically. Since 1990s, the study on the floodplain and delta has entered a phase of stagnation.

Karst in Arctic and Subarctic region in North America contains a wide variety of surficial karst landform characteristics due to not only extensive glacial activities, but also interglacial karst processes during the Pleistocene age.(omitted)
