| Abstract | A Geographical Information System (GIS) has been used for the integration of the results of 70 vertical electrical soundings and hydrogeological data in the piedmont zone of the Himalayan foothills region of Uttaranchal, India. Indian remote sensing (IRS) LISS-III data has been used to prepare thematic maps for the geomorphology and slope maps of the area. The ranges of electrical resistivity values have been assigned to the different formations by calibrating electrical resistivity values with the borehole data. Electrical resistivity, groundwater level monitoring, and borehole and remote sensing data have been integrated in the GIS analysis to delineate the hydrogeological zoning in the study area. Suitable weights were assigned to the different features affecting the groundwater potential. The total score for a particular location is translated in terms of groundwater potential of the area. The results indicate that the southern part of the study area has a very good groundwater potential for meeting the demand of water for irrigation and domestic purposes whereas the steeply sloping area in the northern part, having high relief, has a poor groundwater potential. The resulting delineation of groundwater potential zones are in general agreement with the available yield data of the tube wells.Un système d’information géographique (SIG) a été utilisé pour l’intégration de résultats en provenance de 70 sondages électriques et données hydrogéologiques dans la zone de piedmont, au pied de l’Himalaya dans la région de Uttaranchal en Inde. Des données du satellite IRS LISS-III ont été utilisées pour préparer des cartes thématiques sur la géomorphologie et les pentes de la zone d’étude. Les valeurs de résistivités électriques ont été assignées aux différentes formations en les calibrant sur les données de sondages. La résistivité électrique, la piézométrie, et les données de sondages et de télédétection ont été intégrées dans une analyse par SIG pour délimiter les zones hydrogéologiques de l’aire d’étude. Des poids ont été assignés aux différents éléments affectant le potentiel en eau souterraine. Le résultat final pour une localisation particulière est traduit en terme de potentiel en eau souterraine. Les résultats indiquent que la partie Sud a un potentiel très bon pour la demande en eau domestique et eau d’irrigation, tandis que les zones plus pentues dans la partie Nord, caractérisée par un relief élevé, présente un potentiel assez pauvre. La délinéation globale des zones à différents potentiels s’accorde assez bien avec les données disponibles concernant la capacité des puits.Se ha utilizado un Sistema de Información Geográfica (SIG) para la integración de los resultados de 70 sondeos eléctricos verticales y datos hidrogeológicos en la zona piamonte de la región al pie de los Himalaya de Uttaranchal, India. Se han utilizados datos de sensores remotos Indios (IRS) LISS-III para elaborar mapas temáticos de la geomorfología y mapas de pendientes del área. Se han asignado los rangos de valores de resistividad eléctrica a diferentes formaciones mediante la calibración de valores de resistividad eléctrica con datos de barrenos. Se han integrado datos de resistividad eléctrica, monitoreo de niveles de agua subterránea, y barrenos, y datos de sensores remotos mediante un análisis SIG para delimitar la zonificación hidrogeológica del área de estudio. Se asignaron pesos apropiados a las diferentes características que afectan el potencial del agua subterránea. El puntaje total de un lugar particular se ha transformado en términos de potencial de agua subterránea del área. Los resultados indican que la parte sur del área de estudio tiene muy buen potencial de agua subterránea para satisfacer la demanda de agua por riego y uso doméstico mientras que el área de pendientes pronunciadas en la parte norte, de alto relieve, tiene potencial pobre de agua subterránea. La delimitación de zonas potenciales de agua subterránea encaja muy bien con los datos disponibles de rendimiento de pozos entubados. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
