| Abstract | A simple, physically based method is developed in this paper to assist in the allocation of areas with high groundwater potential and for the determination of maximum allowed pumping rate to ensure proper groundwater management. This method utilizes the aquifer physical properties as well as GIS technology to accomplish this purpose. The design of this method was considered to be applicable in areas with little data, such as in most arid regions. This technique was applied to a catchment in an arid environment where qualitative as well as quantitative analyses of the results were undertaken. Locations of available groundwater and rates of maximum allowable pumping were compared with observations and experiments in the field and a good agreement was found. It was concluded that the best groundwater location was in the alluvial area, which represents only 16% of the total aquifer, which is a typical case in arid region catchments. The rate of maximum pumping was estimated to be 65 m$^{3}$/h. However, to benefit 55% of the area, the maximum pumping rate should only be 40 m$^{3}$/h with an average rate throughout the area (55%) of about 24 m$^{3}$/h.Une approche simple, fondée sur des principes physiques, est mise au point pour faciliter la détermination des régions à potentiel élevé en eaux souterraines et les débits de pompage maximum permettant d’assurer une utilisation durable de la ressource. Cette méthode tient compte des propriétés physiques de l’aquifère et utilise la technologie des SIG. Elle est destinée à l’étude des régions pour lesquelles la quantité de données est restreinte, par exemple, les régions arides. La technique a été appliquée à l’étude d’un bassin versant situé dans un environnement aride, et les résultats ont été analysés, de façon qualitative et quantitative. Le repérage des endroits où se trouvent de fortes quantités d’eaux souterraines ainsi que le taux de pompage maximum permis ont été comparés aux observations et aux essais réalisés sur le terrain, et une bonne correspondance a été constatée. Il a été conclu que les meilleurs endroits pour extraire l’eau souterraine de l’aquifère sont situés dans la région alluviale, qui représente seulement environ 16% de l’aquifère total, une caractéristique typique des bassins versants des régions arides. Le taux de pompage maximal permis dans ces endroits pourrait être de 65 m3/h. Par contre, afin d’exploiter 55% de l’aquifère total, le taux de pompage maximal devrait être réduit à 40 m3/h, pour une moyenne régionale d’environ 24 m3/h.Un enfoque simple basado en la física para asistir en la determinación de áreas con un potencial alto de aguas subterráneas y de la tasa de bombeo máximo permitida para asegurar el manejo adecuado de las aguas subterráneas. Este método utiliza las propiedades físicas del acuífero así como tecnología GIS para cumplir este propósito. El diseño de este método se considera aplicable a áreas con pocos datos, como la mayoría de las regiones áridas. Esta técnica fue aplicadá a un drenaje eligido como área de estudio en un ambiente árido, donde se llevo a cabo un análisis cualitativo y cuantitativo. La ubicación de aguas subterrráneas disponibles y las tasas de extracción máxima de bombeo permitidas fueron comparadas con observaciones y experimentos en terreno. Se encontró una buena corroboración. Se concluyó que la mejór ubicación esta en el área aluvial que representa el 16 % del acuífero, típico de los drenajes en zonas áridas. La tasa de bombeo máximo que se podría permitir es 65 m3-hr. Sin embargo, para el beneficio de 55% del área, la tasa máxima de bombeo permitido deberá reducirse a 40 m3-hr con un promedio en la totalidad del área (55%) de 24 m3-hr. |

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.
