Abstract	A framework for estimating aquifer hydraulic properties using sinusoidal pumping is presented that (1) derives analytical solutions for confined, leaky, and partially penetrating conditions; (2) compares the analytical solutions with a finite element model; (3) establishes a field protocol for conducting sinusoidal aquifer tests; and (4) estimates aquifer parameters using the analytical solutions. The procedure is demonstrated in one surficial and two confined aquifers containing potentially contaminated water in coastal plain sediments at the Savannah River site, a federal nuclear facility. The analytical solutions compare favorably with finite-element solutions, except immediately adjacent to the pumping well where the assumption of zero borehole radius is not valid. Estimated aquifer properties are consistent with previous studies for the two confined aquifers, but are inconsistent for the surficial aquifer; conventional tests yielded estimates of the specific yield—consistent with an unconfined response—while the shorter-duration sinusoidal perturbations yielded estimates of the storativity—consistent with a confined, elastic response. The approach minimizes investigation-derived wastes, a significant concern where contaminated fluids must be disposed of in an environmentally acceptable manner. An additional advantage is the ability to introduce a signal different from background perturbations, thus easing detection.Une démarche pour estimer les propriétés d'un aquifère à partir d'un débit de pompage à variations sinusoïdales est présentée pour (1) dériver des solutions analytiques pour des conditions captives, en drainance, et de puits incomplet convenant à plusieurs applications pratiques, (2) vérifier les solutions analytiques par rapport à un modèle aux éléments finis, (3) établir un protocole de terrain pour réaliser des essais d'aquifère, et (4) estimer les paramètres de l'aquifère à partir de solutions analytiques. Les solutions analytiques soutiennent bien la comparaison avec les solutions aux éléments finis d'un domaine d'écoulement simulé, sauf dans les zones immédiatement voisines du puits de pompage où l'hypothèse d'un rayon de forage nul n'est pas respectée. La procédure de terrain utilise (1) une chaîne d'acquisition de données programmable que contrôlent des pompes à régime variable qui alternativement injectent et extraient l'eau du forage pour créer une impulsion sinusoïdale, (2) un conteneur mobile, au-dessus du sol qui stocke momentanément l'eau de l'aquifère entre les cycles d'extraction et d'injection, (3) des débitmètres à palettes qui contrôlent les débits d'extraction et d'injection, et (4) des capteurs de pression qui contrôlent les niveaux d'eau dans les forages de pompage et d'observation. La procédure est appliquée à une unité aquifère superficielle et à deux unités captives du site de la rivière Savannah, un site nucléaire fédéral de Caroline du Sud. L'approche sinusoïdale fournit rapidement des estimations des paramètres de l'aquifère en évitant les pertes de temps liées aux études.Se presenta un marco para estimar las propiedades de los acuíferos mediante una tasa de extracción sinusoidal. El método (1) deriva soluciones analíticas para condiciones de acuífero confinado, semiconfinado y de penetración parcial, que son aplicables a muchas situaciones prácticas; (2) verifica las soluciones analíticas con un modelo de elementos finitos; (3) establece un protocolo de campo para ejecutar ensayos hidráulicos; y (4) estima los parámetros del acuífero por medio de las soluciones analíticas. Éstas han sido validadas de forma satisfactoria con soluciones numéricas en un dominio simulado de flujo, exceptuando las áreas adyacentes al pozo de bombeo, para el que la hipótesis de radio nulo no se cumple. El procedimiento de campo utiliza (1) un registrador de datos programable que controla las bombas de velocidad variable que inyectan y extraen agua de forma alternativa desde el sondeo con el fin de crear un estímulo sinusoidal; (2) un contenedor móvil, situado en superficie, que almacena temporalmente el fluido del acuífero durante los ciclos; (3) contadores volumétricos tipo noria que registran las tasas de inyección y extracción; y (4) transductores de presión para observar los niveles del agua en los sondeos de bombeo y control. El procedimiento ha sido verificado en un acuífero superficial y en dos niveles confinados del emplazamiento del río Savannah, en Carolina del Sur (Estados Unidos de América), donde se ubican unas instalaciones nucleares federales. El enfoque sinusoidal permite efectuar estimaciones rápidas de los parámetros del acuífero a la par que elimina residuos derivados de la investigación.
