Karst water was defined as 'Water which fills the cavities of the earth continuously and is only subject to gravity and hydraulic pressure.' Karst springs are water outlets from karst-hydrologically active cavities in water-soluble rocks, whether they are on the surface or within the earth. Karst springs behave so differently that the general principles of classification for all springs can be applied to them with a few exceptions. Firstly, classification according to the outflow: perennial springs, periodic springs, rhythemically springs, episodically flowing spring. Secondly, classification according to geologic and tectonic conditions: bedding springs, fracture springs, overflow spring, ascending spring.

최근의 Karst지형에 관한 연구와 더불어 석회동에 관한 연구가 국내외적으로 10년 이상의 연륜을 쌓고 활발히 전개되고 있다. 우리나라에서도 한국동굴학회, 한국동굴협회, 자연보호협회 등을 통하여 활발히 진행되고 있다. 일본에서는 Karst(석회암)지역을 국립공원으로 지정하여 Karst 지형의 보호 및 학습장으로서, 관광지로서 각광을 받은지 이미 오래다. 이와 병행하여 Karst지형에 대한 연구도 각 Karst지형에 박물관을 설치하고 전문적으로 그 지역연구를 담당하고 있다.(중략)

There are lots of depression forms and closed small hollows in the Karst landforms. For example, doline, uvalas, corrosion plains are belong to this case. In Karst surface it can be find that the gorges, meander caves, natural bridges, blind valleys, steepheads and dry valleys are well known landforms.

In karst formation area, the tunnel support system is an important factor for the tunnel safety during operation. This paper presents the simplified tunnel support systems to be adopt in karst formation. For the tunnel planned in the project area, karst features and the expected scenarios in the tunnel area were developed based on the results of the geological and geotechnical assessment. In order to provide specific supporting system and construction details for a wide range of possible karst features, the generalized typical support systems are developed according to the classification of karst features. In addition, the initial support systems and construction sequence for each karst feature are also presented in this paper.

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)

Karst in Korean peninsula is not widely known. Since karst studies had been initiated a few hundred years ago based on the historic records “Dong Guck Ye Jee Seoung Lam” and “Sae Jong Sill Rok Gee Ri Jee” (1993, Oh), modern caverns during the 60s have inactively started to search on the karst phenomena to the eastern mountaineious areas.(omitted)

본역의 Karst Terrain은 태백산맥 준령의 서록상에 위치하여 있으므로 한반도에 분포하는 Karst Terrain 중 고도가 가장 높은 것이다. 그 해발고도는 700m 내외이다. 백복령(833m) 생계령(826m) 자병산(871m) 등은 본역의 태백산맥 준령상에 있다. Karst Terrain이 분포하는 태백산맥 준령의 서측은 완만한 경사의 지형을 이루나 그의 동측은 급경사를 이루어 Karst 제현상의 형성과 발달과정에 매우 특이한 양상을 보여준다.(중략)

Jeongsun limestone formations with good geochemical solution of limestone and physical environments have been developing many Karst landforms. Especially, there are many dolines and most of them elliptical shapes of planes. At present, they have been transformed into uvala toward their long diameter directions. The period of landscape processing is a Quaternary Epoch and Karst cycle corresponds to a stage from late maturity to old stage.

Various types of karst topographies are found worldwide. Owing to their global distribution, karst areas have been extensively studied by scientists who investigate new discoveries by linking the characteristics of karst topographies with their own research fields. However, there have been only a few studies on karsts in the Republic of Korea, and little research exists on their hydrogeology. Fragmentary studies have been conducted on the hydrochemical characteristics of groundwater in limestone areas, the causes of high arsenic concentrations in groundwater, and the hydraulic conductivity of limestone areas. Research on hydrogeological characterization and flow mechanisms in these areas has only began recently. Identification and the proper management of available groundwater resources in karst (limestone) areas is essential as their unique geological characteristics render it difficult to construct reservoirs or dams at appropriate scales. We have reviewed prior work on karsts in the Republic of Korea to provide information that supports water resource security in the karst areas, to improve the understanding of the equitable use of water resources, and to identify the best management practices for groundwater resource resilience improvement.

The purpose of the research was to examine how the quality of service provided by the employee and KARST dealing with the quality of the systems and the information systems affect the satisfaction of the users. Second purpose was to find out which of three factors play greater or lesser roles in affecting the customers of the KARST by examining customer satisfaction and the causal relationship between them so that it can aid in finding areas that need to be further developed or improved when designing and operating airports as well as improve customer service by KARST employees.
