| Abstract | Jeju Island is a volcanic island composed predominantly of permeable basalts. The island is poor in surface water but abundant in groundwater. No actual perennial streams exist and the water resources on the island are dependent almost entirely on groundwater. The groundwater bodies on the island are classified into three general categories: high level, basal and parabasal groundwaters. The parabasal groundwater is further subdivided into lower and upper parabasal groundwaters due to the position of the Seogwipo Formation, which is made up of sedimentary rocks with a low permeability. The distribution of each groundwater type was evaluated through analyses of the spatial distribution of the Seogwipo Formation and the hydraulic gradient of the groundwater. Basal groundwater emerges extensively along the coast of the eastern sector, less commonly along the coast of the western sector. Parabasal groundwater occurs extensively over most of the island except for the southern sector, where it occurs only locally in the coastal area. This paper presents a summary of several studies on the occurrence and features of groundwater resources on Jeju Island, the largest island in Korea. L’île de Jéhuest une île volcanique, constituée en principal par des basaltes perméable. La ressource en eaux de surface est faible, mais l’île est riche en eaux souterraines. Comme il n’y a pas des cours d’eaux permanente, toute la ressource en eaux de l’île dépend des eaux souterraines. Les hydrosystèmes souterrains sont classifiés en trois catégories: des eaux souterraines de haute niveau, des eaux basales et parabasales. Compte tenu de leur position dans la formation de Seogwipo, constituée par des roches sédimentaires à faible perméabilité, les eaux parabasales sont subdivisées en des eaux de haut et respectivement de bas niveau. La distribution de chaque type d’eau a été évaluée en analysant leur distribution spatiale dans la formation de Seogwipo ainsi que les valeurs du gradient hydraulique. Les eaux basales se déchargent surtout au long de la partie est de la côte et dans une moindre mesure au long de côte ouest. Les eaux parabasales se trouvent en grande quantité sur toute la surface de l’île sauf la partie sud où elles se trouvent localement, au long de la côte. L’article présente une synthèse des études concernant l’occurrence et les caractéristiques de la ressource en eaux souterraine de l’île de Jéhu, la plus grande île de Korè.La Isla Jeju es de origen volcánico y se compone de basaltos permeables principalmente. La isla es escasa en agua superficial, pero tiene abundante agua subterránea. No existen verdaderas corrientes perennes y los recursos de agua en la isla dependen casi en su totalidad del agua subterránea. Los cuerpos de agua subterránea en la isla son clasificados en tres categorías generales: De nivel alto, basales y parabasales. El agua subterránea parabasal se subdivide además en aguas subterráneas parabasales superiores e inferiores, debido a la posición de la Formación Seogwipo, la cual se compone de rocas sedimentarias de baja permeabilidad. La distribución de cada tipo de agua subterránea fue evaluada a través de un análisis de distribución espacial de la Formación Seogwipo y del gradiente hidráulico del agua subterránea. El agua subterránea basal aflora en un área extensa a lo largo de la costa oriental, y de manera menos frecuente a lo largo de la costa occidental. El agua subterránea parabasal se encuentra en amplias extensiones a lo largo de la isla, excepto por el sector sur, donde únicamente aparece de manera local en la costa. El presente artículo presenta un compendio de varios estudios sobre la existencia y características de los recursos de agua subterránea de la Isla Jeju, la más grande de Corea. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
