Sensitivity analysis of APLIS method to compute spatial variability of karst aquifers recharge at the national park of viñales (Cuba)

Abstract

In this contribution, sensitivity analysis of APLIS method is realized. APLIS method is based on a GIS analysis where the principal variables which influenced the recharge are taken into consideration, with a special emphasis on carbonate aquifers. The methodology is applied to carbonated aquifers of the tropical mountains at the National Park of Viñales. As the method has been developed from Mediterranean conditions, some modifications were required to improve the soil. The method shows acceptable results taking into account antecedent studies in the area. Results of sensitivity analysis of map removing show that the relative influence in the final recharge map is L>I>S>P>A. The single parameter sensitivity analysis shows some deviations between the empirical and the real weighting.
