| Abstract | Lack of appropriate hydrogeological base maps, poor knowledge of the geology of the Nigerian terrain, lack of infrastructural facilities and absence of a working legislature beset the practice of hydrogeology causing problems in exploration, exploitation, operation, control and management of the abundant groundwater resources of Nigeria.This study shows that Nigeria has about 224 trillion l/year of surface water and about 50 million trillion l/year of groundwater for a population of about 128 million. Domestic consumption need was about 6.0 billion l/year in 2001, indicating that there is an abundant water resource potential.A hydrostratigraphic basin delineation is attempted with ten hydrogeological basins as hydrogeological units, which bring to light the intrinsic causes and solutions to the problems of borehole failures, dam collapses, brine-salt water intrusions, and insufficient water delivery to millions of Nigerians.Le manque de cartes hydrogéologiques de base adaptées, la connaissance limitée de la géologie du territoire nigérian, le manque d'infrastructures et l'absence d'un corps législatif fonctionnel rendent difficile la pratique de l'hydrogéologie en causant des problèmes dans l'exploration, l'exploitation, l'opération, le contrôle et la gestion des abondantes ressources en eau souterraine du Nigeria.Cette étude montre que le Nigeria dispose par an d'environ 224 milliards de m$^{3}$ d'eau de surface et d'environ 50 millions de milliards de m$^{3}$ d'eau souterraine pour une population d'environ 128 millions d'habitants. Les besoins de la consommation domestique étaient en 2001 environ 6 millions de m$^{3}$, prouvant que le pays dispose d'une importante ressource en eau potentielle.Une délimitation hydrostratigraphique de bassins a été réalisée pour dix bassins hydrogéologiques, afin de définir des unités hydrogéologiques, pour mettre en évidence les causes intrinsèques et les solutions aux problèmes d'échecs de forages, d'effondrements de barrages, d'intrusions d'eaux salées et de manque d'eau pour des millions de Nigérians.La falta de mapas apropiados de hidrogeología básica, el escaso conocimiento de la geología del país, la carencia de infraestructuras y la ausencia de legislación dificultan la práctica de la hidrogeología en Nigeria, hecho que causa problemas en cuanto a la exploración, explotación, operación, control y gestión de los abundantes recursos de aguas subterráneas del país.Este estudio muestra que Nigeria tiene de alrededor de 224 km$^{3}$/a de aguas superficiales, y unos 50.000.000 km$^{3}$/a de aguas subterráneas para una población aproximada de 128 millones de habitantes. Las necesidades de consumo doméstico ascendieron a 0,006 km$^{3}$ (6 hm$^{3}$) en el año 2001, lo que confirma que se dispone de un abundante potencial de recursos hídricos.Se esboza la delimitación hidroestratigráfica de diez cuencas hidrogeológicas que actuarían como unidades hidrogeológicas, poniendo de manifiesto las causas intrínsecas y las soluciones a problemas tales como fallos en sondeos, hundimiento de presas, intrusión de aguas salinas y salmueras, y el insuficiente reparto de agua a millones de nigerianos. |

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.
