| Abstract | Proper management of groundwater resources requires knowledge of the processes of recharge and discharge associated with a groundwater basin. Such processes have been identified in the Jakarta groundwater basin, Indonesia using a theory that describes the simultaneous transfer of heat and fluid in a porous medium. Temperature-depth profiles in monitoring wells are used to determine the geothermal gradient. To examine the rules of groundwater flow in the distortion of the isotherms in this area, several methods are compared. Subsurface temperature distribution is strongly affected by heat advection due to groundwater flow. Under natural flow conditions, the recharge area is assumed to occur in the hills and uplands, which are located on the periphery of the Jakarta basin, and the discharge area is located in the central and northern part of the Jakarta groundwater basin. A transition area, which could act as local recharge and discharge areas, occupies the middle of the lowland. Subsurface temperatures show good correlation with the groundwater flow conditions, and the data yield important information on the location of recharge and discharge areas.Gérer convenablement les ressources en eaux souterraines requiert une bonne connaissance des processus de réalimentation et d’émergence associés à un bassin hydrogéologique donné. Ces processus ont été identifiés sur le bassin hydrogéologique de Jakarta, en Indonésie, en utilisant une théorie qui décrit le transfert simultané de chaleur et de fluide en milieu poreux. Les gradients de température sont déterminés à partir des diagraphies de température effectuées dans les piézomètres. Afin d’étudier les règles qui régissent localement les écoulements souterrains au travers des distorsions des isothermes du secteur, plusieurs méthodes sont comparées. La distribution des températures en subsurface est fortement affectée par l’advection de chaleur résultant des écoulements souterrains. En conditions naturelles d’écoulement, l’aire d’alimentation est supposée couvrir les collines et les hauteurs bordant le bassin de Jakarta, tandis que l’aire d’émergence se situe sur sa partie centrale et septentrionale. Un secteur de transition, qui peut se comporter tantôt comme une aire d’alimentation locale, tantôt comme une aire d’émergence, occupe le centre de la plaine. Les températures en subsurface sont bien corrélées avec les conditions d’écoulement des eaux souterraines, et ces données fournissent des informations essentielles sur les localisations des zones d’alimentation et d’émergence.La gestión adecuada de los recursos de agua subterránea requiere conocimiento de los procesos de recarga y descarga asociados con una cuenca de aguas subterráneas. Tales procesos se han identificado en la cuenca de aguas subterráneas Yakarta, Indonesia, usando una teoría que describe la transferencia simultánea de calor y fluido en un medio poroso. Se utilizan perfiles de profundidad-temperatura en pozos de monitoreo para determinar el gradiente geotérmico. Se comparan varios métodos para examinar las reglas de flujo de agua subterránea en la distorsión de isotermas en esta área. La distribución de temperaturas subsuperficiales es afectada fuertemente por advección de calor debido al flujo de agua subterránea. Bajo condiciones de flujo natural se asume que el área de recarga ocurre en las colinas y tierras altas, las cuales se localizan en la periferia de la cuenca Yakarta, y el área de descarga se localiza en la parte norte y central de la cuenca de agua subterránea Yakarta. Un área de transición, la cual podría actuar como áreas de descarga y recarga locales, ocupa la parte media de las tierras bajas. Las temperaturas subsuperficiales muestran buena correlación con las condiciones de flujo de agua subterránea, y los datos producen información importante sobre la localización de áreas de recarga y de descarga. |

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.
