PARTE I Julio Macías Asdrúbal Vargas Francisco Frutos Geología spring tracer test hydrogeology analytic model Fractured aquifer Estimated values for transport parameters are reported for the conditions of a volcanic fractured phreatic aquifer in Costa Rica. Three salt-tracer tests performed under natural gradient conditions were interpreted with the aid of single porosity advective-dispersive analytical solutions for pulse and instantaneous injections. Field breakthrough curves showed a clear asymmetric shape, very common for fractured systems. Applied analytical solutions allowed to gain insights into the understanding of the transport processes involved during solute transport in fractured systems, but did not allow for the reproduction of the observed asymmetrical shape. Flow parameters were also obtained (saturated hydraulic conductivity; effective porosity and Darcy ́s flux). The calculated values are within the range of values repor - ted in the literature for fractured aquifers. 2016 artículo científico 0256-7024 https://www.redalyc.org/articulo.oa?id=45449039008 es http://www.redalyc.org/revista.oa?id=454 Revista Geológica de América Central application/pdf Universidad de Costa Rica Revista Geológica de América Central (Costa Rica) Num.55 |
