This study analyzed the distribution of fluvial landforms, fault-related geomorphic features and lineaments around the area of Ungchon-Ungsang in the Dongrae Fault, and discusses the charateristics of geomorphic development based on those. As a result, the NE-SW lineaments are predominantly developed in many numbers within the study area, and the NW-SE or N-S secondary lineaments are developed induced by multiple deformation with the Yangsan Fault. Geomorphologically, the early tectonic history of the Ungchon-Ungsang basin is largely divided into three stages ; 1) the Tertiary fault activity and formation of fracture zone, 2) development of erosional basin, 3) local crustal movements and development of fault-related topography. It is assumed that alluvial fans, deflected channel and stream piracy were formed by local tectonic movements related to faultings during the Quaternary.

충남 천안시 장재천 유역의 최상류부 구릉에 분포하는 '천안 백석동유적그룹'에서 확인된 총 205기의 청동기시대 주거지(이하 주거지)를 대상으로 최적 입지의 지형환경을 구명하고자 하였다. 이를 위하여 주거지가 분포하고 있는 조사구릉을 8개의 사면 미지형으로 구분하고 이를 다시 5개의 경사도 등급과 조합하여 총 40개의 극미지형으로 세분하였다. 이를 바탕으로 '미지형별 경사도' 관점에서 '천안 백석동유적그룹'의 '주거지 수'와 '주거지 분포밀도(단위: 주거지수/1000m²)'를 분석하였다. 그 결과, 주거지가 입지하는 최적의 지형 환경은 크게 5개의 극미지형 - ①정부평탄면의 평탄지, ②정부평탄면의 완경사지, ③정부사면의 평탄지, ④정부사면의 완경사지, ⑤정부사면의 준완경사지-인 것으로 밝혀졌다. 본 분석자료는 향후 장재천 유역에 거주했던 청동기인들의 주거지 분포를 예측할 수 있는 기초자료로 활용될 것이다.

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.

한국의 범람원에 관한 최초의 논문은 1960년대 후반에 발표되었다. 1970년대와 1980년대의 한국의 범람원과 삼각주에 관한 연구는 권혁재(고려대학교 명예교수)와 조화룡(경북대학교 명예교수)에 의해 주도되었다. 권혁재는 그러한 연구의 기초를 확립하였고, 조화룡은 충적지형을 미시적 관점에서 분석하였다. 1990년대 이후, 범람원과 삼각주에 관한 연구는 정체 상태로 접어들었다.

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)
