  • 산악지역의 유출은 지형적 특성 때문에 매우 빠른 반응시간을 가지고 첨두유량 또한 매우 크게 마련인데 이러한 특성 때문에 산악지역의 돌발홍수 발생 메카니즘과 이것의 정확한 규명은 지금까지 수많은 연구과제의 주제가 되어왔다. 본 연구는 산악지역의 유출 특성을 잘 반영한다고 알려진 수문지형학을 기초한 지형기후학적단위도(geomorphoclimatic unit hydrograph, GCUH) 이론을 토대로 단일유역 산악지역과 분할유역 규모의 유출 특성을 규명하고 각각의 유역특성에 맞는 돌발홍수예경보시스템을 제안 및 비교 검토하고자 한다.

  • 본 연구는 산경표에 기초한 최근 한국 산맥논의를 검토하였다. 산경표는 풍수지리학에 기초를 둔 우리나라 전통 산맥 체계로 분수계 체계이다. 이 체계에 기초를 둔 논의들은 하천이 산맥을 절단하고 있는 것을 받아드리지 못하며, 이 체계의 중심 맥인 백두대간은 많은 기원이 다른 산맥들을 연결하여 이름하고 있다. 지형학에서 산맥은 구조 운동이나 차별 침식의 결과로 형성된 산지의 선적 배열이다. 같은 원인에 의하여 형성된 산지의 선적 배열을 하나의 산맥으로 이름을 부여하고, 형성 원인이 다르거나 방향성이 다른 것을 합쳐서 하나의 산맥으로 이름 하지 않는다. 지형학에서 정의되는 산맥은 선행 하천에 의해 절단될 수 있고, 분수계 이동 현상도 일어나기 때문에 산맥이 분수계와 일치하는 것은 아니다. 따라서 백두대간이란 이름은 우리나라의 상징성을 표현할 때 사용하고, 교과서에서는 우리나라의 지형을 설명할 때는 기존의 산맥체계를 사용해야 할 것으로 본다.

Comparative Analysis of Geomorphological and Folklore Approaches to Weathered Landforms - Focusing on Tafoni, Gnamma, Gamsil and Alter - (풍화지형에 대한 지형학적 분석과 고고민속학적 접근에 관한 비교 연구 - 타포니와 나마, 감실과 알터를 중심으로 -)

  • Typical weathering landforms and phenomena including tafoni and gnamma are usually interpreted as man-made alteo (praying water bowl) or dragon-alteo by folklore researchers. Despite some terminological ambiguity, they are certainly natural weathering pits and are introduced in our discipline for fifty years, however, unfortunately most of them are interpreted as petroglyphs used and prepared for ritual ceremony. Several seemingly artificially-made rock holes are also found in many places, but most of them are weathered landforms by salt weathering. Author believes that communication effort to use common language and publish more researches in interdisciplinary journals are very essential to propagate scientific achievements made by geomorphologists to other discipline. Also geomorphologists specialized in weathering processes are encouraged to participate in preservation of stone artifacts and archaeological remains.

  • Place names or toponyms including Gosan, Busan and Buraesan can be very important and interesting storytelling subjects in terms of geomorphology and folklore studies also. Several studies done by folklorists, those sixty five mountain-moving stories with similar names can be grouped into several categories through formation processes and origin, transport media and imposition of tax. Geomorphological studies can focus on transport media. They can be classified into six different categories; 1) flood from upstream through river, 2) voluntary walk of mountains, 3) by wind, 4) upwelling from underground, 5) involvement of mythical beings such as Mago Granny or Dokkaebi (kind of goblin), or 6) migration by ocean current.

  • 'Green growth' is the development strategy for the sustainable society through the harmony between the environment and economy. The 'green growth' was defined and accepted by UNESCAP and countries in Asia-Pacific region. OECD also accepted it as their new development policy. 'Green New Deal' was also proposed as a new social/economic policy to response three global crisis: environmental, resources and economic. Social and environmental sustainability are the most important principles of this policy. In Korea, however, the 'green growth' is redefined and used by the government and politicians as an economic policy to support the new technology on energy efficiency and renewable energy. In here, the definitions of green growth in the world and in Korea are analysed and compared, and new term is proposed. Green growth is the development policy to response environmental crisis (ie. climate changes) to transform the society to environmentally and socially sustainable one. The possible contribution of geomorphologic researches to green growth was also proposed.

  • This work is to elucidate in typological aspect main geomorphological processes in the morphogenetic system of Mongolian steppe zone. Its morphogenesis manifest interaction of intense gelifraction and active erosion either by slope run-off or by wind. Intense gelifraction owes both to cold temperature regime with great amplitude, and to moisture associated with snow fall. Erosion of material produced by gelifraction is assured by surface run-off of summer rainfall and spring eolian activities. The geomorphological landscape sculptured by such morphogenetic processes manifest low-relief smooth slopes. This feature reveals that intense gelifraction keeps abreast with removal of weathering product by surface run-off and wind.
