Influencia del sismo de Golfito del 30 de julio de 2002 (Mw 6,2) sobre una prueba de bombeo en el acuífero confinado del sitio de presa del P.H. Pirrís, Costa Rica

Abstract: Con el fin de determinar los parámetros hidrogeológicos del acuífero fracturado de tipo confinado encontrado en el sitio de presa del Proyecto Hidroeléctrico Pirrís, se realizó una prueba de bombeo que se prolongó durante 2560 minutos, con un caudal promedio de 1,9 l/s, utilizando una bomba sumergible de 5,6 kW. Aproximadamente a los 420 minutos de iniciada la prueba fue perturbada por un sismo con una magnitud de 6,2 MW con epicentro a 133,7 km de distancia, ocasionando una importante modificación en el régim… Show more

“…Hydraulic transmissivity (T) determines the flow of groundwater that is transmitted through a vertical strip of aquifer unit width under a hydraulic gradient unit (Palafox-Avila, 2008). This parameter is required in numerical flow modeling processes (Painter et al, 2007;Asfahani, 2016); horizontal recharge of fresh water (Cruz-Falcón et al, 2013); in the determination of the radius of influence of the descent cone of the well (Vargas, 2016) in order to determine the perimeters for the protection from contamination of the well water, and water management, among others. It is useful to estimate the groundwater resource and its integral management (Tizro et al, 2012).…”
